What is the difference between Object Literals and Array Literals in JavaScript? I know it has something to do with the length method but i don't fully understand it.
How do I reset an asp.net validation control via JavaScript? The current code sample clears the error message text but does not reset the validation control for the next form submission.

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?
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,
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[0] = new Array(6,7)
node[1] = new Array(5,-4,8)
node[2] = new Array(-2) //Here, invalid array length
I do not know how to resolve this error.
I don't end my JavaScript statements with semicolons when newlines will work. No flames, please. My question is, is there an automatic indentation package for vim that will work?

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?
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 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).
I want to format dates in a specific format but I can't figure out how to add my date function to the JavasScript view engine in CouchDB. Preferably I would like to add my formatDate() function to the prototype Date object so it is available everywhere Does anyone know how to add this so that the CouchDB JavaScript View engine will see it?
Applet Communication:
write a small applet and embed it in html-file with following functionality.
1. change applet bg color by receiving a javascript command with the color parameter.
2. show dynamic mouse position in applet-window and display position in html-site. use live-connect between applet and browser communication.
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.
Hi,

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?
Ok so I'm trying to access the first element of a JSP list,
here's what I've come up with so far without any kind of luck:
onclick="alert('<%=list[0]%>');"
What's the best approach to access the first element and eventually to pass it to a javascript variable/function ?
I've heard that the <% %> tags are deprecated and some are suggesting relaying on JSTL/EL how can one use those without having to iterate the entire list and put a breakpoint for the iterators ?
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"
if a user types in an input say 3 into a text box three small text boxes should be shown below or in a popup through javascript or jquery .How can this be done...

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

Hi, I have many controls in table and I want to disable all the controls using JavaScript upon clicking of some checkbox.

just wondering if anyone knows anything of using javascript to set html to new content instead of linking to new pages, if this is generally a bad idea or if it kind of hurts SEO(which im kind of new to)
Basically the home page displays given content, and the links to like contact pages and stuff, just change the body content to what would normally be a separate html page. my OCD kinda bugs me when pages reload and either flash the background or its offset somehow, so i wanted to know if making sites like this was a bad idea or whatever-
i suppose at the least, i could create duplicates/hidden pages for SEO purposes
I want to pass data to id
<script language="javascript" src="/foo.aspx?id=1"></script>

bunch of thanks.
