Basically i have this code:
$(document).ready(function() {
$("form").hide();
$(".show").click(function() {[code]....
i am trying to make this code work on an array, ie. i have a for loop spinning out content from my data base and want to be able to to use this function on each paragraph of code individually.Of course i can make the loop increment useing i++ on this links and element ID for example, but i have no clue how to hand this in anyway to the jquery code.

I'm new to javascript, but I need help and really hoping for a reply. I was trying to find an answer in Google but no result. So I have two table containing images, at the beginning only first table is displayed. Then when one of the images in the first table is clicked, a second table should appear, and user should click one of the images on that table. And that image should replace the one that was clicked originally in the first table.
So the question is, when the user clicks an image in the second table, how do I know what was originally clicked in the first one? I tried to use global variable but that doesn't work.

I have the following issue - if a user select 'select box' as a value in a drop-down list, a new window is opened where they can enter values then they should click on a button and a text thay have typed should pass to a hidden field in the parent window.
How do I do this? I tried this (child window)
<html>
<head>
<title>Values</title>
</head>
<body BgColor = "#FFFFFF">
<form name = "f1">
<textarea name = "ta"></textarea><br />
<input type = "button" value = "Ok" onClick = "getValues ();" />
</form>
<script language = "JavaScript">
function getValues ()
{
window.alert ( document.f1.ta.value );
parent.aff.vals.value = document.f1.ta.value;
}
</script>
</body>
</html>
But unfortuanelly it's not working!

I am confused about the true difference between the two below examples.
first example:
// Demonstrating a problem with closures and loops
var myArray = [“Apple”, “Car”, “Tree”, “Castle”];
var closureArray = new Array();
[code]....
Here we iterate through the length of myArray, assigning the current index of myArray to theItem variable. We declare closureArray 4 times as an anonymous function. The anonymous function in turn declares the predefined write() function, which is passed parameters. Since write() is in closureArray() a closure is created??? During each iteration, theItem is reassigned its value. The four closures reference this value. Since they reference this same value and since this value is reassigned ultimately to the value of the fourth index position, tHe time we execute closureArray later on, all four closures output the same string. This is because all four closures are within the same scope "the same environment" and therefore are referencing the same local variable, which has changed.
I have a couple of problems with this example:
1) I thought a closure is a function that is returned - the inner function is not returned above.
2) theItem is not even a local variable of the parent function (closureArray) - I thought in order for a closure to work, the inner function only accesses the local variables of the outer function, but in this case the local variable is defined OUTSIDE of the parent function.
3) the "the four closures are sharing the same environment." The thing is even in the second example, they are sharing the same environment.
Second example:
// A correct use of closures within loops
var myArray = [“Apple”, “Car”, “Tree”, “Castle”];
var closureArray = new Array();
[code]....
Here we iterate over the length of myArray (4 times), assigning the index of myArray to theItem variable. We also return a function reference to the closureArray during each iteration (closureArray[i]), where i is index number so we assign 4 functon references. So when we iterate through myArray, we immediatelly call the writeItem() fucntion passing an argument of theItem at its current value. This returns a child anonymous function and when that child function is called, it will execute a block that calls the predefined write() method. We assign that returned anonymous function to the variable closureArray. Hence, closureArray holds a reference to that anonymous function. So closureArray during each iteration holds a reference to the anonymous function and we later call closureArray, which in turn calls the anonymous function, therefore calling the predefined write() function to output the local variable of the parent function. This outputs each distinct index of myArray.
This is because since we created the closure, when we call writeItem, passing theItem argument, since theItem is a local variable of the parent function of the closure, it is never destroyed when we later call closureArray (the reference to the child anonymous function)? Yet weren't we using a closure in the first example as well? So whey wasn't those variables preserved?
I don't think it has anything to do with assigning a returned anonymous function to closureArray. Even though an anonymous function creates a new memory position in the javascript engine, therefore not overwriting the other function references we create during the iteration, it's still referring to a local variable declared outside the reference. So if it's about the closure retaining value of parent's local variable even after exiting the parent function allowing for the current indexes to be preserved, then why did the closure in the first example fail to retain each index?

I am creating a job ticket object that will interact with a database. It has to update the database on the fly via AJAX. Within the job ticket object, I have instances of a Component Object. Within the Component Object, I have an instance of an Editor Object. One of the methods of the Editor object is a function to edit some text and when it's submitted, it will update the database. All of that is working fine. My problem is that I need to refresh the screen with the new contents of the database. I have a method in the Component Object that refreshes the screen, but how do I call it from within the Editor Object? I believe it has to be called there because the editor object has a handler for the form submission and the AJAX function. So I'll have to reference a callback function once the AJAX request is handled, but I don't know how to call it.
I know that sounds kind of convoluted, so hopefully, this very simplified code will paint a better picture of what I'm trying to do:
Code:
Now I want to call refreshScreen, but I don't know how:

It is day two of the same problem (and day two of learning Ajax, day five of Javascript)
The current code (below) does nothing; it does not go into the showContents function. Switching the order of some items would cause it to enter the function, but it would always alert that the xhr status was 0. I guess this is an improvement?
php doc that is getting requested (I don't think the error is here as the problem is that it is not even initializing):
Code:
javascript code that is requesting the information:
Code:
I need to pass the num variable because the fields I am dealing with are part of a bunch of fors that create an unspecified number of fields titled 1source, 2source, 3source, etc.

I have a function for totalling decimal values provided in textboxes
that form a column on a webpage. This script should total the values
in the textboxes, displaying the result in the final
'optotalprogtime' text box formatted as a decimal.
Here is what I've got so far, but I'm getting annoying "object
expected" errors on the line where I attempt to format the number (as
indicated by the comment below)
//realtime calculation formating as minutes (decimals)
function opprogtotalcol() {
alert("in opprogtotalcol");
document.getElementById('optotalprogtime').value = 0;
for (var rowNumber =1; rowNumber <= 12; rowNumber++){
document.getElementById('optotalprogtime').value =
parseFloat(document.getElementById('optotalprogtim e').value) +
parseFloat(document.getElementById('opprogmin' + rowNumber ).value);
}
if(!isNaN(document.getElementById('optotalprogtime ').value)){
//only works for numbers
document.getElementById('optotalprogtime').value =
formatNumber(document.getElementById('optotalprogt ime').value,
2);//format number here
}
}
Any insight would be appreciated.
To head off concerns about wrapping code correctly, my code is
wrapping pretty bad in this form, but in the acutal page I have long
lines that do not wrap.

I have a situation where there is a matrix grid of checkboxes, and individual entire rows or columns must be able to be toggled between checked and unchecked state.
[Code]...
Simple, right? But the columns part, I can't figure out. I put everything in each column in the same class, with the hopes that on click, I'd be able to figure out a way to take the class value of the link - (this).className - and use it to target checkboxes in the same class. But I have no idea how to do this. I haven't been at jquery that long. I'd be incredibly grateful for some help, a starting point, a command that would work....

I have a CF application that accepts two dates. The first date - Out Date - is required. The second date - Return Date - is optional, but if populated, must be equal to or greater than the Out Date. Here's the screen & code:
9974
<script type="text/javascript">
function compareDate()
{ if(document.editleave.temp_ret_date.value != "01/01/0001")[code]....
Everything works fine....EXCEPT...if the Return Date is invalid, I cannot click on the calendar box to select a date (or open another browser session). Basically, IE is locked up until the user manually types in a valid date.This ain't good.I want to be able to trap the error, just like I have, but I still want the calendar selection box to be usable.Is it possible to "reset" the error condition after the intial warning to only trigger on the onSubmit parameter?

I'm doing this site for my c=school and needs this event calendar. Ive traipsed through this far but stuck with the event showing up. The problem is it will double print the dates that have events. One from the for loop which shows events and other from the normal if function. Following are my files.
calendar.html

<html>
<head>
<title>Calendar</title>
<link href="calendar.css" rel="stylesheet" type="text/css" />

I'm having issues with the animate procedure in jQuery. I should start by saying that while I am not new to web developement and scripting, I am fairly new to jQuery so this may be fairly elementry to some of you pros out there.
Basically what I am doing is I have an image map with hot spots, when you mouse over a hot spot, another image (an enlarged version of the hot spot) appears (fading in and growing) and then disappearing on mouse out (fading out and shrinking). My problem is odd because it does not happen every time, but "sometimes" when you mouse over the first animation (grown and fade in) will run then second will run (shrink and fade out) and then repeat until you click outside of the hot spot and the popped-up image. I've noticed the problem mainly occurrs in Firefox (3.5) and rarely or never in IE (8) and Chrome (2).

I'm using Jquery to create a rollover effect on 2 images (placed on top of each other) to fade the bottom image in on a mouseover and out on a mouse out. Clicking the faded in image also opens a fancybox gallery. The problem is that sometimes the animation (the fade in and out) gets stuck after closing the fancybox window and the mouseover doesn't work anymore.
Here's my code for the mouseover:

Here is the code -
Let me explain what is going on. Inside of a div with the id = navContain, are a few images. These images are used as navigation links. These images have the class = imgPos. When you roll over one of these images, the css top property adds 92 pixels.
The image contains two different colored variations of the word "HOME." When the image is in its off state, the word home is white. When you roll over the image, jQuery animates it so that the white text of the word "HOME" slides down, and then a colored version of the word "HOME" slides down and takes its place. This is the same image, just its top property is being changed. jQuery does nothing more than change the top property.
The problem: Sometimes when you roll your mouse over it for the first time, it properly animates to the over state, but then gets stuck in that state even when you mouse off of it. Still in its over state, if you mouse over it again, the over state jumps up and down violently. It never goes back to the state where the text should be white - its original state.
I've tried the stop() function, as you can see in my code. Still, this problem persists and I can't seem to figure it out alone.

I am trying to learn SVG and I have alot of the basics including javascript manipulation. But I am really stuck on trying to manipulate the actual text itself.
<text id="text1" x="300" y="200" font-size="60" font-family="tempus sans itc" stroke="red" stroke-width="2" onmouseover="changeText()">
OMG
</text>
I am trying to change the text "OMG" to say something else when you hover over it. For example: It says OMG, I want to hover over the text and have it change to WTF. Like you could do with innerHTML. anybody have any experience with SVG

I have a php page which returns a table representing a query sent to a MySQL database. So far it has worked in every case except now that I'm trying to use it to call a stored procedure, in which case the readystate is staying at 1 and never completing.
I have logged the results of the php file both in an error log and looked at the response from the request using firebug, both of which show a correct result.
Why isn't this returning properly?
Here are the relevant javascript functions:
Code:
function customizeType()
{
$("custom-header").innerHTML = "";
$("custom-top").innerHTML = "";
[Code]....
After the page loads, the error log shows correct results for all queries.
