i'd guess the offending line is in mscross:
Object.prototype.objRef = null;
Good catch. It's strictly verboten to add to Object.prototype. That will
break all kinds of things, not just jQuery.
Totally agreed, but we could still make jQuery more robust:
for (propName in obj) {
if (obj.hasOwnProperty(propName)) {
// do something with property...
}
}
jQuery is supposed to be used with lots of third party code (which
propably will extend the object here and there), so maybe we should
think about that.

2. get selection and create range
3. clone this range twice, collapse one copy to left and the other to right
4. insert span (id='left_boundary) at left, and span
(id='right_boundary' at right
5. try $('#left_boundary').next()[0].nodeName, get SPAN - it skips the text
but $('#left_boundary')[0].nextSibling.nodeName gives me #TEXT_NODE
why cant i use jquery to access TEXT_NODES? or: what can i do to get it working?

Re: [jQuery] oninput bug workaround
Hi John,
Oninput is a firefox event, it fires whenever the text being
displayed would change, e.g. after a paste (so it's similar to the IE
event onpaste). Onkeypress won't catch right-click pastes or auto-
completion, and I believe that onchange doesn't fire until the field
loses focus.
Anyway, it's not really a jQuery problem, there is a bug filed for it
(since it clearly doesn't function even when used directly). I was
just hoping there might be a jQuery way to implement the workaround
to avoid dragging in other libraries that aren't otherwise needed.

Re: [jQuery] Is there a way to endAll()?
To savely restore the state, you could do something like this (untested):
jQuery.fn.plugin = function() {
var oldStack = $.merge( [], this.stack );
// do other stuff
this.stack = oldStack;
return this;
};
By merging the current stack into an empty array, a copy of the current
stack is created, which can then be used to restore the stack.
Another solution:
jQuery.fn.plugin = function() {
var oldState = $(this);
// do other stuff;
return oldState;
};
This would return the same state, but a different object. If your code has a
refernce to the jQuery object before the plugin is called, the reference would
point to a different object then the one that is returned by the plugin.

Re: [jQuery] jquery update causes js error
it looks like mscross had objRef to maintain the scope he wanted. (though he didn't need to extend Object.prototype). in jquery when you attach an event, this in a callback refers to the html element that was clicked or mouseover-ed etc.
in his lib, he is saving a reference to an html element in objRef, which he uses later to set the scope. another way would be to use .apply/.call or just use jquery. -bOn 10/9/06,

[jQuery] jQuery Browser Detection
Currently, jQuery does a browser detect by checking the user agent.
However, I think object detection would probably be a better way.
This code does that by detecting unique obects on the window object.
However, I am not sure what is unique to Safari.
// Figure out what browser is being used
jQuery.browser = {
safari: /webkit/.test(b),
opera: !!window.opera !!window.opera.defineMagicFunction,
msie: !!window.clipboardData,
mozilla: !!window.XPCNativeWrapper
};
The chance of someone defining 'window.opera.defineMagicFunction',
window.clipboardData' and 'window.XPCNativeWrapper' is virtually non
existent (far far less likely than someone changing the user agent
string).
defineMagicFunction
(http://www.opera.com/support/tutorials/userjs/specs/) is used by user
scripts on Opera, clipboardData
(http://msdn.microsoft.com/workshop/author/dhtml/reference/objects/clipboarddata.asp)
is for working with the clipboard and XPCNativeWrapper
(http://kb.mozillazine.org/XPCNativeWrapper) is used by privileged
code (i.e. extensions) to access unprivileged code (i.e. content on a
webpage) in a secure way.

Re: [jQuery] Performance question
Thanks for all your responses. I actually do all the things that you mentioned: reusing the jQ object, chaining, setting a context, etc. Actually it would be helpful to have some performance analysis on the different kinds of queries, such as searching by ID, by element, class name, attribute, xpath queries, context-delimited, etc., because even though it's somewhat straightforward to know that a search by ID is faster than searching by class name, it'd be interesting (and useful)to know by how much.

Chaining methods is helpful so you can avoid re-querying. If you need to put other code in betwen method calls then reusing the same JQuery object by
putting it into a variable beforehand is worth while to save requerying. If you're going to do several queries inside the same parent element (s) then
a combination of the above will be a big help. Those sound like good suggestions to me, though I'm no expert. Something I try to keep in mind is the relative speed of different
types of queries. This has been mentioned on the list before, but in case you didn't see it, references to IDs are fastest, followed by elements, and then classes. At least, that's how I've understood
previous discussions of the topic. So: a.$('#my-id') is faster than $('div#my-id'), and b. $('div.my-class') is faster than $('.my-class') Hop that helps.

Re: [jQuery] jQuery Browser Detection
I'm inclined to disagree.
I believe that one should use object detection for cases in which they are
invoking that object for it's functionality. A prime example is the XHR
(although MS may be messing around with that in IE7).
But, if one is best served by simply knowing what browser we are dealing
with, one should absolutely use the user agent string. It's where the
browser vendor *tells you* what browser it is. Why hack around, when the
vendor is telling you what you need to know?
For example: you need to apply a hack to get around one of IE6's infamous
layout bugs, when dealing with a dynamic web application. Are you going
to test for XHR or window.clipboardData? No, you ask the browser what
browser it is. If it's IE6, (or IE 5.5 if the bug is there, too), code
for that instance. We should avoid being obtuse in our code.
Summary:
1. Use object detection to detect objects, when you don't have to care
what browser you're using, as long at the object exists and will do what
you want it to.
2. Use the user agent string when you're more interested in what browser
you're actually using (by name) than you are in whether or not that
browser has a specific object available.
- Brian
Currently, jQuery does a browser detect by checking the user agent.
However, I think object detection would probably be a better way.
This code does that by detecting unique obects on the window object.
However, I am not sure what is unique to Safari.
// Figure out what browser is being used
jQuery.browser = {
safari: /webkit/.test(b),
opera: !!window.opera !!window.opera.defineMagicFunction,
msie: !!window.clipboardData,
mozilla: !!window.XPCNativeWrapper
};
The chance of someone defining 'window.opera.defineMagicFunction',
window.clipboardData' and 'window.XPCNativeWrapper' is virtually non
existent (far far less likely than someone changing the user agent
string).
defineMagicFunction
(http://www.opera.com/support/tutorials/userjs/specs/) is used by user
scripts on Opera, clipboardData
(http://msdn.microsoft.com/workshop/author/dhtml/reference/objects/clipboarddata.asp)
is for working with the clipboard and XPCNativeWrapper

Sam, if that's a problem with your user base, then there are issues that go beyond the technical. If my users were that hackish and black-hatted, I wouldn't be giving them any front-end code at all if I could avoid it. I mean, if people are technically savvy enough to change their user agent string, what stops them from overriding the functions that you provide, as well? I say, we split the difference. Leave jquery's browser detection as is, and offer jUntrustworthy as a plugin, which overrides the original implementation with one that uses object detection. - Brian On 09/10/06, Brian Miller [EMAIL PROTECTED] wrote: I'm inclined to disagree.

Re: [jQuery] How to implement file upload using AJAX?
You can't use ajax to send files. It's not supported because it's not permitted. The libraries that do it (e.g. Yahoo UI) create a hidden iframe on the fly, with a form inside the iframe (that has a file upload control), which gets submitted. It's as much of a pain as it sounds like it is. Other efforts use Flash or a Java applet to help. That said, it's possible that someone can put together a plugin that implements the iframe hack. - Brian Hi, Does anybody know how a file pload using AJAX can be implemented in JQuery?

Re: [jQuery] jquery update causes js error
Thank you very much! That was it.
[Object.prototype.objRef = null;]
Any idea why that would have been done in the first place?
Probably because the person who wrote that code didn't know any better!
I ran into another issue that all my for loops in code I added to
mscross were returning a null objRef at the end of the loop
and I had to add code to detect that and break out of the loop.
This is all a little new to me and I'm still learning.
Yes, that is the same problem that broke jQuery. The Object.prototype.objRef
= null; assignment adds an objRef property to *every* object.
Stephen, as I wrote in the other post, to avoid these
problems, you should use these loops like this:
for (propName in obj) {
if (obj.hasOwnProperty(propName)) {
// do something with property...
}
}
But not every browser supports hasOwnProperty. Safari doesn't. Does IE 5.5?
In the Object.prototype is verboten article someone posted a comment with
code to implement object.hasOwnProperty, but the code isn't exactly speedy.
(And it has one bug - it should use === for the comparison instead of ==.)
I wouldn't be too keen on adding this overhead to jQuery or my own code.

I believe that jQuery has a sort of built in queue in that effects are
chainable. So you'd simply write all of the effects in one long chain and
each of them would happen in the order you specify in your chain.
Exactly, so doing:
$(#foo).slideDown('slow').slideUp('slow');
will be queued completely.

Re: [jQuery] IE7 May be Pushed out Tomorrow
Just to set expectations on timetables, MS said they would eventually push IE7 out as a high-priority patch a few weeks after general release. So although tech-savvy users may be able to download the final IE7 within a week or two--and many already have IE7 RC2--Aunt Abby probably won't have it for at least several weeks longer. According to Microsoft, you'll see a different alert window for the update when it arrives. They have a picture of it here: http://blogs.msdn.com/ie/archive/2006/07/26/678149.aspx Release must be getting close, though, I just got an email that they are doing one final chat on IE7 this week: http://blogs.msdn.com/ie/archive/2006/10/09/Last-Expert-Zone-Chat-Before-We- Ship-IE.aspx If MS released on their typical Patch Tuesday schedule, the most likely dates for the push would be November 14 or December 12. Big companies often have embargoes on non-essential updates during November and December (too many holidays and vacations) so they may defer IE7 installation into 2007. As far as Microsoft is concerned, ordinary consumers can get updates any time Microsoft is good and ready to send them, so this patch may come out on an unusual day. If we are really unlucky, MS will push IE7 out on an odd day like November 21 and ruin Thanksgiving day for geeks all over the USA. Instead of relaxing with a beer and watching football, or eating turkey around the table with the family, I'll sit with a plate dripping gravy in my lap trying to fix my mom's computer as she says, It just started doing that on Tuesday, now my favorite web sites don't look right! ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
Re: [jQuery] Performance question
I have a somewhat related observation. I have discovered that when selecting by ID, the context parameter does not matter. In other words, these two statements are functionally equivalent:$(#myId);
and$(#myId, myContext);It's as if when the id selector is passed then the $ method just uses a document.getElementById. Besides the fact that this may produce unexpected results, it also means that you should be careful when using IDs to try to gain performance. Because if the size of your markup is large then this
$(#myId, myContext);may actually be slower then this$(.myClass, myContext);I have definitely seen performance gains by using the second one over the first.Brendan

analysis on the different kinds of queries, such as searching by ID, by element, class name, attribute, xpath queries, context-delimited, etc., because even though it's somewhat straightforward to know that a search by ID is faster than searching by class name, it'd be interesting (and useful)to know by how much.

Chaining methods is helpful so you can avoid re-querying. If you need to put other code in betwen method calls then reusing the same JQuery object by
putting it into a variable beforehand is worth while to save requerying. If you're going to do several queries inside the same parent element (s) then
a combination of the above will be a big help. Those sound like good suggestions to me, though I'm no expert. Something I try to keep in mind is the relative speed of different
types of queries. This has been mentioned on the list before, but in case you didn't see it, references to IDs are fastest, followed by elements, and then classes. At least, that's how I've understood
previous discussions of the topic. So: a.$('#my-id') is faster than $('div#my-id'), and b. $('div.my-class') is faster than $('.my-class') Hop that helps.

if(sSelector.parentNode) { listNodes = [sSelector]; } else { var listNodes = parseSelector(sSelector); if(listNodes.length == 0){ return false };
}replacing:var listNodes = parseSelector(sSelector);
if(listNodes.length == 0){ return false };Then, I created a little plugin:jQuery.fn.sIFR = function(namedHash) { $(this).each(function() { if(typeof sIFR == function) {
sIFR.replaceElement(this, named(namedHash)); } });}the namedHash is the hash required by sIFR, so you can now do stuff like $(.links li:not([ul])).sIFR({ sFlashSrc: sifr/gotham.swf,

Re: [jQuery] Performance question
From: Brendan O'Brien
I have a somewhat related observation. I have discovered
that when selecting by ID, the context parameter does not
matter. In other words, these two statements are
functionally equivalent:
$(#myId);
and
$(#myId, myContext);
It's as if when the id selector is passed then the $ method
just uses a document.getElementById.
Indeed it does just that. See this code in jquery.js:
var re2 = /^([#.]?)([a-z0-9\\*_-]*)/i;
var m = re2.exec(t);
if ( m[1] == # ) {
// Ummm, should make this work in all XML docs
var oid = document.getElementById(m[2]);
r = ret = oid ? [oid] : [];
t = t.replace( re2, );
} else {
if ( !m[2] || m[1] == . ) m[2] = *;
for ( var i = 0; i ret.length; i++ )
r = jQuery.merge( r,
m[2] == * ?
jQuery.getAll(ret[i]) :
ret[i].getElementsByTagName(m[2])
);
}
Besides the fact that this may produce unexpected results...
Well, IDs are supposed to be unique in a document, so $(myId,myContext)
doesn't seem all that useful even if the code did make use of it. It would
reject the case where #myId exists but is outside of myContext, and work the
same as the current code in the the other two cases (myId doesn't exist, or
myId does exist inside myContext).
Is that what you were trying to do - operate on element #myId but only if
that element is inside myContext, ignoring it if that element is outside
myContext? If that's not the requirement, then you can just leave out
myContext.
it also means that you should be careful when using IDs
to try to gain performance. Because if the size of your
markup is large then this
$(#myId, myContext);
may actually be slower then this
$(.myClass, myContext);
I have definitely seen performance gains by using the second
one over the first.
That's an interesting result. I would have guessed (hoped?) that #myId
should be fast even in a large document - don't most browsers load all the
IDs into a hash table? I wonder how the comparison turns out in different
browsers.
You might try the comparison with $(myId) instead of $(#myId,myContext),
but I'll bet it wouldn't make any difference since the code doesn't use the
context. (This should certainly be documented if it isn't already.)

oh, and one more thing. it seems the new jQuery version also won't
execute the AJAX (.load) calls I'm using inside other (common, not
jQuery) javascript functions. also deprecated?
I've googled all around and found nothing yet, so I hope I can get
some pointers over here. thanks everyone in advance.
regards,
Tomas

Re: [jQuery] new jquery breaks $(document).load ?
$(document).ready doesn't work every time. that's why I had to use .load. When does .ready break? It shouldn't break in any modern browser. Do you think you could clarify the situation at all? --John ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
Re: [jQuery] new jquery breaks $(document).load ?
you're right. it does work all the time.
however, the AJAX .load function doesn't. could it be because the call
is being made inside a normal JS function?

ready is fixed in the new versions, it works fine in all supported browsers.

is there a reason as to why .load breaks in the new versions of jquery?
Use $(document).ready(function() { //stuff });

hello everyone,
i'm currently developing a site for which jQuery has proven to be more
than useful. the problem is that I updated the .js (I'm using the
compressed one) since I was having problems with the Interface plugin
(jQuery is not defined). however, now the page won't execute whats
inside the $(document).load function.

Re: [jQuery] How to implement file upload using AJAX?
Refer messagehttp://jquery.com/discuss/2006-August/009877/if anyone is in the mood for creating an upload plugin :-) On 10/9/06, Brian Miller [EMAIL PROTECTED] wrote: You can't use ajax to send files.It's not supported because it's notpermitted.The libraries that do it (e.g. Yahoo UI) create a hidden iframe on thefly, with a form inside the iframe (that has a file upload control), which gets submitted.It's as much of a pain as it sounds like it is.Other efforts use Flash or a Java applet to help.That said, it's possible that someone can put together a plugin thatimplements the iframe hack. - Brian Hi, Does anybody know how a file pload using AJAX can be implemented in JQuery? If so, please give me an example. I intend to use PHP for the data receiving, but the problem is the sending actually.

Re: [jQuery] IE7 May be Pushed out Tomorrow
Great points Dave. I'm more concerned about people that have automatic updates set to just install versus prompting. Thats why I sent out this alert. Considering how MS threw in WGA as a critical update for many Windows users without really letting them know what they were getting, I wouldn't put a foced upgrade to IE7 past them. Rey... Dave Methvin wrote: Just to set expectations on timetables, MS said they would eventually push IE7 out as a high-priority patch a few weeks after general release. So although tech-savvy users may be able to download the final IE7 within a week or two--and many already have IE7 RC2--Aunt Abby probably won't have it for at least several weeks longer. According to Microsoft, you'll see a different alert window for the update when it arrives. They have a picture of it here: http://blogs.msdn.com/ie/archive/2006/07/26/678149.aspx Release must be getting close, though, I just got an email that they are doing one final chat on IE7 this week: http://blogs.msdn.com/ie/archive/2006/10/09/Last-Expert-Zone-Chat-Before-We- Ship-IE.aspx If MS released on their typical Patch Tuesday schedule, the most likely dates for the push would be November 14 or December 12. Big companies often have embargoes on non-essential updates during November and December (too many holidays and vacations) so they may defer IE7 installation into 2007. As far as Microsoft is concerned, ordinary consumers can get updates any time Microsoft is good and ready to send them, so this patch may come out on an unusual day. If we are really unlucky, MS will push IE7 out on an odd day like November 21 and ruin Thanksgiving day for geeks all over the USA. Instead of relaxing with a beer and watching football, or eating turkey around the table with the family, I'll sit with a plate dripping gravy in my lap trying to fix my mom's computer as she says, It just started doing that on Tuesday, now my favorite web sites don't look right! ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/ ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
[jQuery] jQuery 1.0.2
Hi Everyone - jQuery 1.0.2 is now ready for consumption! This release is a huge bug fix release - and it is highly recommended that you upgrade right away. As always, if you spot a bug, please add it to the bug tracker. In addition to having a better test suite, a big push for this release was to have better cross-browser compatibility for common tasks (such as AJAX operations). Functionally, however, no major features have been added to this release (although, expect some new code come 1.1). I'd like to take this opportunity to introduce everyone to Jörn Zaefferer. Much of this release was made possible by him. He's responsible for completely overhauling the test suite (it now has over 260+ tests!) and for fixing the majority of the current bugs and enhancements (over 60 of them!). If you want someone to thank for this release, it should be him. * jQuery 1.0.2 http://jquery.com/src/jquery-1.0.2.js * jQuery 1.0.2 Compressed http://jquery.com/src/jquery-1.0.2.pack.js Thanks, everyone, for your support. --John ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
