Since I played around with OpenFire Server, I started to make up my mind to build an IM Client connecting to this Server. So, I quickly do some research on this by looking for any library based on JavaScript with Flash. Unfortunately, I cannot find any. Does anybody know where to get source? Thanks!

I'm trying to load a cross domain javascript file, and want to pass a variable along on the query string. I have seen the above '#' method used, but am unsure of how to extract the 'foo' value from within the file.js. Any clues how to handle this without the aid of server side help?
Thanks.
I'm looking for articles or books that discuss schemes and techniques adopted by pro javascript developers to store and organize data with html tags. In other words, how to emulate xml data storage with html as semantically as possible.
Some various solutions that I've seen mentioned in passing are custom DTD, custom attributes with xhtml, early adoption of html5 and its data- attribute.
Now, I'm looking for some tangible material that goes in depth with these concepts.
I have been writing my first jQuery plugin and struggling to find a means to time how long different pieces of code take to run.
I can use firebug and console.time/profile. However, it seems that because my code executes so fast I get no results with profile and with time it spits out 0ms. (http://stackoverflow.com/questions/2690697/firebug-profiling-issue-no-activity-to-profile/2690846#2690846)
Is there a way to get the time at a greater level of detail that milliseconds in javascript?

I'm developing an application with javascript. What I need is to have divs with id's (1,2,3...) and be able to insert a div between, for example, 2 and 3, with jquery, and then have that be the new three, and three becomes four, four becomes five, etc. I've got the div insertion working, I just need to know how to reorder the divs. Any ideas?
I was implementing a routing algorithm in javascript, but when I assign a negative one variable in the array gives me this error: invalid array length.
var node = new Array()

node[2] = new Array(-2) //Here, invalid array length
I do not know how to resolve this error.

I've been having a crack at some of the problems over at http://projecteuler.net/ with JavaScript. I've been using a simple html page and running my code in script tags so I can log my results in the browsers' console. When experimenting with loops I sometimes cause the browser to crash.
Is there a better environment for me to do this kind of development?
Say i have a string that i need to evaluate in javascript such as :
window.some_class.update( 'Runner', 'update_runner', '{"runner":{"id":"1","name":"Nin's Lad" } }');
In order for eval() to evaluate it, i need to escape the apostrophe in runner_name (Nin's Lad). Is this possable with regex? I dont want to escape the single quotes around Runner and update_runner. I'd just like to escape any single quotes inside double quotes.
Thanks,
Good Day!

I have a print function on a page in my website. the problem is, when it hits this line:
<script type="text/javascript" src="http://cdn.powerreviews.com/repos/12564/pr/pwr/engine/js/full.js"></script>, it tries to load it, and just never finishes.
Any ideas on how to get around that?
I think I have not got the syntax correct for writing a javascript function and calling it to assign its return value to a variable.
My function is:
getObjName(objId){
var objName ="";
$.ajax( {
type : "GET",
url : "Object",
dataType: 'json',
data : "objId="+objId,
success : function(data) {
objName = data;
}
});
return objName;
}
I am trying to call it and assign it to a variable with:
var objName = getObjName(objId);
However Eclipse is telling me that "the function getObjName(any) is undefined"

Is there a way to add a method to all javascript functions without using the prototype library?
something along the lines of :
Function.prototype.methodName = function(){
return dowhateverto(this)
};
this is what i tried so far but it didnt work. Perhaps it is a bad idea also if so could you please tell me why?
if so can I add it to a set of functions i choose
something like :
MyFunctions.prototype.methodName = function(){
return dowhateverto(this)
};
where MyFunctions is an array of function names
thank you

I Have a PerformancePoint Server 2007 Dashboard in a Sharepoint 2007 page.
In my Sharepoint page, there's 2 Filters who get passed to the Report, and I need to print this report in the page (in another button, not the SSRS one).
So what I need is a javascript method that calls the SSRS print button, which is on a named DIV, inside a WebPartZone that only have one WebPart, a PerformancePoint Dashboard Item (don't know the exact name of the webpart).
Hello,
I'm running into a scenario where at random times I am getting "Access Denied" when executing javascript. It is not repeatable and occurs in random places of my application. There is not indication of what is causing it in the logs and I'm really at a loss on this. It seems to be UI problem only. However, there is no reason it should appear as I do not have any such permission checking to could be getting triggered.
Thanks in advance
