[Proto-Scripty] Re: Event.observer with mouseup?
Another alternative is to use Prototype's Curry function which let's
you create new functions with default arguments.
So you could write:
Event.observe(window, 'mouseup', alert.curry('hi'));
Joe
As long as you know what curry does, I think this is more obvious for
really simple examples like this.

Doesn't have to be anonymous. Named functions are fine:
function myMouseUpThingy() {
alert('Howdy');
}
// later
Event.observe(window, 'mouseup', myMouseUpThingy);
The critical thing is that you need to pass in a function *reference*.

Try doing this instead:
//put the following in a script block near the bottom of your html
var foo = function(){ alert('howdy') };
Event.observe(window,'mouseup',foo);
Note that the function is called Event.observe, not Event.observer.
Also any reference to a function inside of an observer needs to be in
the form of an anonymous function, not a literal function itself. You
could have done this as well:
Event.observe(window,'mouseup',function(){alert('howdy')});
It's a subtle distinction, but it becomes much more important in a non-
trivial example, because an anonymous function won't get its input
variables (and won't be called, either) until it is invoked. Then it
uncloaks, does its business, and vanishes again.

Hi,
I'm new to protocoljs, but it's this thing I'm trying to do, and it
doesn't work. It drives me mad.
Anyway,
I try to do this with protocoljs:
body onmouseup=alert('hi');
This was how I wrote it, but it doesn't work:
Event.observer(window,'mouseup',alert('hi'));
What is the right way to do it?
Thank you!

[Proto-Scripty] Re: emptyFunction() calls take up to 30% of execution time
I think this will solve itself. If I understood the announcements on
Squirrelfish correctly, they are trying to inline small calls. So that
a call to emptyFunction would become a noop.
On 24 Dez. 2008, 21:35, npepinpe n.pepi...@gmail.com wrote:
The Prototype.emptyFunction is just a dummy function; it doesn't
actually do anything.
emptyFunction: function() {}
It's often used as a default option for callbacks and such, so that
you can still call the callback even if the user hasn't specified
anything. It shouldn't affect running time as it adds very minimal
overhead.
The only way I can see how to circumvent this would be a massive patch
to Prototype to remove all references to Prototype.emptyFunction and
instead have type checks before function calls which might be the
emptyFunction. But maybe someone has a better idea.

[Proto-Scripty] Ajax.Updater doesn't work correctly in IE6
Hi there. I have an application that uses Ajax.Updater to render some data inside a div based on user input - This is fairly vanilla app using Prototype 1.6.0.3 and the code of my simple page is listed here: http://gist.github.com/42983 Now this Ajax.Updater call works correctly in IE 7, IE8 BETA, Firefox 2 and 3, Opera, Safari and even my iPhone safari browser :) but it does not work correctly in IE6. Unfortunately I still have a few users that have IE6 on their desktops and I see 2 different types of behavior. In one instance, the browser crashes when Ajax.Updater fires and in another instance, only part of the data is rendered. I have Fiddler (HTTP debugging proxy) running and I see the entire payload delivered with an HTTP status of 200 but the browser chooses to render just part of it. And so either the browser crashes or it doesn't work but the latest Prototype release does not seem like IE6. The data coming back is HTML form data with input fields, checkboxes and select boxes with some script data and I have evalScripts set to true. Is this a known issue? Is there a fix or workaround for this? I'd hate to revert back to an earlier version of Prototype and miss out on all the benefits of v1.6.0.3. Any guidance would be greatly appreciated.

[Proto-Scripty] Re: Calling other website server url
If the page/service you're trying to consume will only take POST requests,
you can make the Ajax call to _your_ server which then creates a proxy Http
call to the endpoint with the appropriate headers and whatnot. Most server
languages support this via some sort of HttpClient class.
I'm assuming julien's comment is along those lines, though I'm not a php
dude.
... and Jerod's solution will only work if the endpoint you're calling
returns javascript.

[Proto-Scripty] window.createPopup() and permission denied
I've got a web application written in classic ASP that uses the
window.createPopup() method for context menus. When a menu item is
selected, the onClick for the item is parent.myFunction(). Note:
this is all one page: I'm not scripting across frames, iframes,
domains, anything; all one page, all one domain.
Been working great for two years.
I've introduced Prototype and Scriptaculous, and now this same code
produces a permission denied error. I've tried the following
scenarios:
onClick=alert('clicked!'); works fine
onClick=myFunction(); error: object required, of course
onClick=parent.myFunction(); error: permission denied
I've tried plugging in Proto.Menu, but it's not as plug'n'play as the
authors would like to think, and (as always) deadlines loom. Given
that there are several systems over which I have maintenance duties,
I'd just as soon not have to rewrite them all.
Is there a fix for this? Or a workaround? Something I'm missing?
Thanks!

[Proto-Scripty] Sortable tree
Ok, I am really not the biggest JS guru on the planet. Consider me a newbie on SU and javascript. So, alright, here is the big plan: I have my small to do list and I want to be able to drag around items in the list. tasks can have subtasks and that should be the end of the line. no sub sub tasks. I am far away from realizing that. I think it might have been smarter to implement this directly using SU's drag and drop abilities. however, what i did try was forcing sortables to do what i want and i did not come far. not only am i far away from realizing the 2-level restriction; more importantly, i can't convince the library to allow drops on empty items. i gave them an empty sublist. i turned on drop on empty. i added a display:none child element to the sublists. nothing! in an ideal work, i would tackle the problem like this: in happy world, sortables would allow leaves to get child nodes without obstructions. i would set the only attribute to a class name, and after every update, i would update the classes so that only elements on the first level would have this class set, so nothing can be dragged beyond level 2. also, after every update, i would check if level 3 got created (could happen( and would smoothe it back to level 2. could someone give me a hand, please? regards, niko --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

`alert.curry(hi)` won't work in IE, where `window.alert` is not an

`Function.prototype` (as, pretty much, any other JScript host method).
You can, of course, try to call `curry` from the `Function.prototype`
directly (`Function.prototype.curry.call(window.alert, 1)`), but since
`curry` internally tries to invoke `call` directly on a context
object, this will fail once again. It would work if Prototype.js was
invoking `call` from the `Function.prototype` rather than from the
context object `(Function.prototype.call.call(alert, window, 1))` but
it doesn't and it's not clear if such change is even worth the
trouble.
Never expect anything from host objects.

Consider that DOM elements are simply one way of displaying the data in business objects. Do all of your work with the objects, then send the data to the screen to be viewed. That model separates the business logic from the display logic. Of course there are some functions that are pure UI (e.g. sorting a table or list) but others, like updating the table rows from a server, should be done with an object, then written to the UI. If you only have one table representing a single data object, it probably doesn't matter if you just update the table directly using AJAX or similar, but once you have a number of data objects and maybe a number of different ways of displaying their content, you will want to separate display from business logic. -- Rob. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.
