A question for a jQuery expert. I'm more familiar with Prototype, but I've been using jQuery a lot recently and needed to find out how something is done, jQuery style Prototype has a rather handy wrap() function which lets you wrap an existing function within another function. It lets you attach code to be executed before or after an existing function is called.[URL]...

I have a function I call to see if people leave form fields empty. I have been asked by a client to check to make sure of the person's date of birth as well. They gave me the script, however, I am unsure how to do implement it. How do I add this to my existing checks? Code:

I came across Marijn's helper function again called forEach. It does just what it sounds like it does, and is one of those things one would consider adding to their own personal little library like getElementsByClassName...My question is, I've heard/seen that Mozilla (and only Mozilla at this point) indeed HAVE a forEach function, and I do most of my beginning testing in a recent-stable Mozilla browser, so I'm not 100% sure but I think the Mozilla forEach might work... what happens if I write my own and I keep the name?
So if there's some default forEach that the browser natively understands, and then I have a function in my lib that has the same name, does mine take precedence over the native one, or not? Is it just safer giving libraries slightly weird names so new in-built functions can't possibly interfere?So also, if later browsers end up implementing the newer Javascript (2?) that as I hear, will implement a getElementsByClassName, would this break, or ignore, everyone's pre-made getElementsByClassName, assuming they are called the same name?

modifying an existing function which controls the highlighted states of a multi level js accordion menu. I have had to use javascript due to certain css elements not working in safari browsers.My problem is due to the multi level aspect as when a sub link is clicked, the parent link above it then deselects. I need the parent link to stay active when its sub links are clicked and only deselects when a link outside of that list is clicked upon.I understand the theory of adding a conditional statement but simply don't know how to apply it correctly within the functionHere is the existing function which tells a link to be active or selected:var Lst;
function CngClass(obj){
if (Lst) Lst.className='.topnav';
obj.className='selected';

I have an existing JavaScript function that cycles through a bunch of colors depending on how many clicks of the mouse made.The all works fine, but I have since my code a little more complex, so now the colors are remembered once the user goes back to this page.. this is done with PHP and mySQL. The problem is that, once they go back the color may be red (2nd in the cycle), meaning next click they would expect to see orange, but the click counter is back to 0 so they actually see green.The code is:
Code:
<script type="text/javascript">
function countClicks (obj){

I'm trying to add a unix timestamp into an exisiting function, but am uncertain how you add the variable. I searched the boards here, and came across this example to convert a date to unix in javascript. var date3 = new Date(Date.parse("21 May 2009 10:03:20")); And I'm trying to add it to this: flashobj3.addVariable ("targetTime", $date3);

I'm using jQuery 1.4 to hide a div (#cartPop) when the "close" link inside of it (#cartPop a) is clicked. Since I'm using animate() to fade the div out (opacity), I also have to use hide() to get rid of the div once it has faded out (otherwise the invisible div, which is on a higher z-index, blocks the elements on a lower z-index).
Code:
The problem is that the hide() function calls immediately without waiting for the animate() function to run. Even if I append a delay() function before hide() like so:
Code:
...it still doesn't wait.

I am trying to minimize the amount of script that I use on my website. I have sections of each page; each section has the same basic layout. The divs and images that I want to make appear and disappear all have nearly identical ids, the only difference is the number at the end of the id.Is there a way to get one script to automatically detect which id number has been clicked and then show all elements with the same number at the end of the id? I would also like it to hide the elements in the hide function below (basically they are the elements that do not share the same id number).I currently have everything working the way I want it to using multiple functions like the one below but I woul
$("#2thumbNail2 , #ledBar").click(function () {
$("#type201 , #type203 , #type204").hide();

I have 2 javascript files: 1 containing generic functions for my site used sitewide and another for a particular web page containing just the javascript for that page. The page is also calling the jQuery javascript file.
What I want to do is have a javascript function in my main javascript file which uses features of jQuery such as show, hide etc. and then I want to call this javascript function from the other page specific javascript file.

This does not work and so was wondering if anyone can point me in the right direction as to how to achieve this or something similar.
I am having a strange problem with a javascript function that does not return the value but returns the code inside the function. My best guess is that I am incorrectly calling the function hasLandedOn()and jquery is interpeting it. Why is this happening? I highlighted the parts in red.-Tom ReeseThe following is returned NOT the variable imageName.
function hasLandedOn(){
var selectorLoc = $("#selector").offset();

I'd like to create a generic function to save repeating a lot of code and then just pass in the relevant values.
I'm fine with that, the only thing I'm not sure about is if/how I can pass in a function name to be called on success/fail.
This post is where I was doing something similar to save repeated code: [URL]
In a similar way is there a way of passing in a function name to be called on success?
I have issue with passin value between functions:

What I want out of this function is the variable newworkdays to use in another function.
How do I access the "newworkdays" outside the function? I've already try to declare the variable outside of the function, though that resulted in that I didn't get the value of the variable inside the function.
i've got a function which makes a call to the database( via jquery $.post) to check if a username already exists. All the data I get back is fine and both the conditional statment works as intentded.

Would like to do this:
The function setEqualHeight(columns) fires on document.ready and works well. However, in the second function (the tab function) I would like to to call the setEqualHeight function in order to recalculate the div heights again. I would like to do this in the "onclick function". How?
