[jQuery] JQuery Xpath working?

2007-03-02 Thread Jeff Lawson 
Hi,

I'm having trouble getting xpath selectors to work well, particularly  
on XML responses from ajax requests, using FF.  Hoping somebody can  
help.  Here are the steps I'm taking:

1.  Perform an ajax request using Prototype's Ajax.request, with an  
onComplete callback to my function.  Here's a sample response:

?xml version=1.0?
XMLResponse
   Errors/
   Warnings/
   Messages/
   Response
 ProductType
   Id40/Id
   NameChain/Name
   ProductGroupBMX/ProductGroup
   Margin/
   Properties
 PropertyTemplate
   Sid44c0ade1561d3/Sid
   ProductTypeId40/ProductTypeId
   PropertyTypeId34/PropertyTypeId
   PropertyType/
   Required0/Required
   NameWeight/Name
   Type1/Type
 /PropertyTemplate
   /Properties
/ProductType
   /Response
/XMLResponse


2.  In my function, calling jQuery(//ProductType/Properties/ 
PropertyTemplate) on the responseXML property of the response.   I  
get zero elements.

3.  Replacing the jquery with a css-style selector, works:  jQuery 
(ProductType Properties PropertyTemplate) returns 1 element.

I'd prefer to use xpath over css.  Any thoughts?  Thanks!

[jQuery] Xpath and tab selection

2006-11-02 Thread radius 

So I have a tabbed navigation system, and I am using jquery to
auto-select the current tab.
Here's the html:


ul id=main_nav
  li /services/ SERVICES /li
  li /store/ STORE /li
  li /about-us/ ABOUT US /li
  li /gallery/ GALLERY /li
  li /press/ PRESS /li
/ul


Here's my jQuery code (adapted from
http://leftlogic.com/info/articles?id=1):


if (location.pathname.substring(1)) {
   $('#main_nav [EMAIL PROTECTED]' + location.pathname.substring(1) +
']').parent().attr('id', 'current');
}

I'm using parent() so that the id gets applied to the 'li' element and
not the 'a' element.

All of this works. However, I'm unclear about a couple of things:

First, why is the dollar sign $ necessary in the xpath statement? i've
seen no documentation on it, and when i try it without the dollar sign,
it doesnt work.

Second, Sometimes I have a url like: /about-us/4/3 and my jQuery
statement fails because the href != location.pathname.
How can i rewrite this statement so that it searches for the href value
in the location.pathname value and applies the id to the matching
string?

Thanks in advance,
dd

Darius,

$= means attribute ends with.  Check out
http://jquery.com/docs/Base/Expression/CSS/ , the Supported, but
different section.

Taking a close look at the selection documentation might also help you
with item #2 a bit.

You're going to have to figure out how to text-match your relative URL
with the absolute URL that will be in location.pathname using plain old
regular expressions.

Keep in mind that IE automatically converts relative URLs to absolute ones
in memory, while the other browsers don't.  This may affect your results.

Re: [jQuery] Xpath and tab selection

2006-11-02 Thread radius 

Thanks a bunch for that link, Brian. I really did search the documentation,
and I feel crazy for missing that rather obvious link from the XPath
section.

I ended up going the less-than-elegant route and breaking out of jQuery to
use the JS match() function, but it works nicely:

if (location.pathname.substring(1)) {
$('#main_nav').find('a').each(
function() {
if(location.pathname.match( $(this).attr('href') ) )
$(this).parent().attr('id', 'current');

});
}


Cheers!

 Sorry about that, it's now fixed in SVN rev 442.

NP, thanks for the updates.

OK, this is good in FF, in IE6 no errors, but returns a '' for the xpath 
queries instead of the correct results.

2006-10-14 Thread John Resig 
Stephen -

After doing some testing, it seems as if the culprit is the '//' that
you have in front of your expression. It's perfectly ok to remove it -
as it will continue to work correctly.

It seems to be that if you do .find(//foo) or $(//foo, context) it
freaks out. But this is ok, since doing that is completely redundant
in jQuery. Just remove the // to make it .find(foo) or $(foo,
context) and you'll be fine.

I'm still not entirely sure /why/ this happens - but it does. Here's
the ticket for it:

Does changing this fix the problems that you were having related to bug #164?

jQuery does not claim to implement the XPath standard. It just supports

Re: [jQuery] XPath expressions not working

2006-10-03 Thread Raziel Alvarez 
I sent an email yesterday, but maybe it didn't got through. 

Anyway, this is it:

I have this simple markup:

componentDom.innerHTML = 

form action=""> h1 name=formTitle/h1 p name=formInstructions/p div name=top /div div name=formContent 
divname=columndiv /div/div /div div name=bottom input type=submit name=defaultButton value=Submit/ 
 /div/form

I'm executing this xpath calls with the following results:

$('form/[EMAIL PROTECTED]', componentDom).length = 3
$('form/[EMAIL PROTECTED]', componentDom)[0].innerHTML =
$('form/[EMAIL PROTECTED]', componentDom)[1].innerHTML= DIV name=\column\DIV/DIV/DIV
$('form/[EMAIL PROTECTED]', componentDom)[2].innerHTMLINPUT type=submit value=Submit name=defaultButton 
$('form/[EMAIL PROTECTED]/input', componentDom)Object requiredError
$('//div', componentDom)'undefined' is null or not an objectError
$('form//div', componentDom).length= 6

$('form//div/input', componentDom).length= Object requiredError


I don't understand why it's failing. I'm just asking for the input which it's obviously there, under the last DIV. Like this, I've come across many really simple XPath queries that just don't work. Am I doing something wrong? Is it XPath actually supported? 


Moreover:

Thos queries that return an error, like: 

$('form//div/input', componentDom);

break in the siblingfunction(elem, pos, not) since elem is null. Probably this is related to the bug where children() breaks when there are no children.

I know jQuery doesn't support the full XPath standard but as you can see my expressions are really simple, andanyway it shouldn't break.

Thanks

[jQuery] XPath Axes: ancestor(-or-self) / parents / descendent / children

2006-09-25 Thread George Adamson 

I'm interested to know how to extend the selector syntax to accept things
like axis definitions etc. (I know from the forum that we should be using
the .parents() methods etc but I'd like to extend the selector syntax
myself.)

While the .parent() and .children() methods etc work very well when combined
with the excellent XPath-style selector support, I'm finding many situations
where axis selectors such as ancestor:: and ancestor-or-self:: etc (or a
shorthand) would be very useful in the selector expression itself as an
alternative. (Note: The // syntax is already a good way to do some
descendent:: like functionality.)

I'm gradually building up a simple 'selectors' plugin to add selectors that
are not in the core. Another kind member has already explained how to add to
the :expr selectors so I have already developed :focus and :hover, with more
on their way (such as those in the docs pages that are not actually in the
current jquery release).

Please note that I'm not trying to restart this debate, I'm just after info
on the best way to provide axis filters in the expression strings. Adding to
the :expr is easy enough because they just need to return true or false. I
just can't figure out how to enable axis:: selectors.

Many thanks,
George Adamson

 Ok, this fixes one problem, but a further error occurs on line 641:

 It appears that the getAttribute method on XML elements only accepts
 a single argument:
 
   return elem.getAttribute( name );
 
  From the MS docs the second argument of 2 forces the method to be
 case-sensitive, which if I'm correct, isn't required by any browser
 other than IE. So is it possible to detect whether the browser is IE
 and the document is an HTML doc - in which case use the two args method,
 otherwise call with just one arg.

Sorry, I got this wrong - it doesn't force case sensitive.

According to the docs:
2 - Returns the value exactly as it was set in script or in the source 
document.

Now I'm even more confused, what else would it return?

[jQuery] XPath '[EMAIL PROTECTED]' doesn't work on XML documents

as you see the message is a bit vague, i don't see a function
call here or an attempt at assigning a property!

I've attached demonstration files html/js/xml.
(.js renamed to .jsx - as the mail server rejected it!!!)

BTW, this works fine in Firefox, what a surprise! ;)

 their typelib wrong it may be trying to call getAttribute rather than check
 elem for a getAttribute property. Can you replace that last line with this
 and see if it works?

 } else if ( typeof(elem.getAttribute) != undefined ) {

I just committed this to SVN.

Hi,

 Can I use jQuery's xPath capability to locate an element in an arbitrary
 XML file loaded using Ajax?

Yes:

$('/my/[EMAIL PROTECTED]',XMLDOMDocument)

 Can I use jQuery's xPath capability to locate an element in an arbitrary XML 
 file loaded using Ajax?

Yes! For example:

$.post(test.xml,function(data){
  $(//foo/bar,data).each( ... );

  // or, with CSS:

  $(foo  bar).each( ... );
});

It's important to note that jQuery only supports a very very small
subset of the full XPath spec. More details here:

Re: [jQuery] XPath

2006-08-15 Thread Fil 

I want the expression to verify that the link is in the correct data
structure, i.e. inside a dt that is inside a dl and where
$(this).parent().next() is a dd.

Said differently: I want to tell my script if the link is inside a dt
then show() the corresponding dd (if it exists).

That's why I was trying to use XPath and the parent::x syntax (and failed
miserably, ha ha).


 In the SVN build of jQuery you can do:
 
 $(this).parent().next().show();

  I have the following structure:
 
 dl
  dta href=urlx/a/dt
  ddtext/dd
 /dl
 
 
  I select the a element in this, and I want to show() the corresponding dd.
 
 
  This works but is not very precise:
  $(../../dt/../dd, this).show();
 
  I'm trying to write it more precisely with something like:
  $(parent::dt/parent::dl/dd, this).show();
 
  but I'm not finding the correct expression...

$(dl dt a).click(function (event) {
  event.preventDefault();
  event.stopPropagation();
  $(this).parent().next().show(); 
});
