how to access parent functions variables?
I'm new to web programming in general, so bear with me as some of my methods may not be entirely correct. What I currently have working is I have a webpage which contains a DIV, which I am using to load another webpage via javascript(which calls itself, in order to get an auto-refreshing effect). The webpage that's being loaded is detecting if a process is currently running on the server and writing some console output while it's running, and what I want to do is stop the auto-refreshing when the process completes. (I can detect when the process stops already).I'm trying to figure out how to properly set this variable from my page that's being refreshed, since it's being loaded in a DIV I figured there has to be some way to retrieve the parent's information.

I'm new here, and new to js. Here is my problem: I have written out a code to make an image switch from state 0 to 1 and back to 0 again (an eye blink). The code works fine, but I would like to write the functions with arguments so it could be applied to more images. I have tried for a few hours (and searched forums) and am getting no where. Here's my code.
Code:
function home_blinkDown()
{
//alert('blink down');
var t = setTimeout("home_blinkSwap('home_js', 'images/main/home_blink.png')", 2000);

I've just developed a plugin that mimics the combo box control, albeit it's a special one. That's being defined as follows:
function
$
{
$.fn.extend
{
[Code].....
But this isn't possible, since the $myList variable is a jQuery object. So I just defined some functions, say, $.smartList.getSelectedValue and the like... but in this approach, I've to pass the jQuery object to this functions as a mandatory parameter and this really sucks. i.e., I need to get the selected value of $myList this way:
var value = $.smartList.getSelectedValue
$myList
;
I've created an object with properties and methods. The object is associated with a form. The object iterates through the form and finds any inputs that are required. It then uses each to apply validation to each of the found inputs. From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object. How do I access the containing object?

I cannot findout how I can write to global variables in a a JQUERY function.

I'm trying to trap a user entry that cannot be found in the database. When a code is entered, the page should give a "Code Not Found" message if it is an undefined value.

How to access the functions defined in scripts of URL loaded in iframe using jquery ?Following is the much more elaboration of question :I have Sample.html :
<html>
<head><script type="javascript">
function sumfunction(var i, var j)
[code]....
I have a parent document which has an iframe loaded in it. The iframe has an textfield element. I want to access this textfield element from the parent document. I have tried the following. But that doesn't work.
(from the parent)
window.frames['frame01'].document.getElementById('idname')
I always get as null.
Is it possible to access the parent context within $.post to asign the result to the parent selection?
See this code here:
$("a[href='country#']").click(function(event) {
var dieBusinessUnit = 'THIS VAR SHOULD CONTAIN RESULT OF $("businessunit", xml).text())';
[Code].....
for some time I always found a workaround for this kind of problem. But somwhow, it feels wrong. So I'd like to know, if there's a common way to solve something like this[code]...
I'm defining the function and if the value of 'obj' hasn't until the function really gets called, this can work. But it just feels so wrong do have always global variables just to access them inside of a callback.[code]...

I would like to display the number 1 at first and then 2. but this code produces number 2 for both alerts. I was able to achieve what i wanted with "new" constructor when creating functions but this is not a good practice and after all i am passing these functions as an event handlers and it can't be done with "new" keyword because it is throwing error. I think there are some solutions with arrays e.g the x would be an array of numbers, but i don't like it. Am i missing something important?

Looking at the code, you might assume (as I did) that clicking the button on page1.htm would load page2.htm. However for some reason, when calling a parent function, the function runs with the calling file's path rather than the path of the parent.
So it is actually trying to load /files/files/page2.htm! How do I force all calls to parent.function() to run with parent.hta's path as the root?
Realize that this is a simplistic example and simple solutions such as putting all the files in the same path, or dropping the "/files" in the loadPage2() function are not valid solutions.
Essentially I need to call parent.loadPage2() and have it run the function with the root path = parent.hta's path.

Parent:

I have a webpage with an IFrame in it. The content for the IFrame could change per page and with it size. I don't want scrollbar's inside the IFrame but rather for the whole page. To accomplish this I must resize the height of the IFrame (width = fixed). But I can't seem to accomplish this. The links within the Iframe load the new content but I have to access the parent document to be able to resize the IFrame height. How I can resize the iframe from within javascript in the IFrame.
