Access Functions From Parent Html
Aug 19, 2011
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'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 added the Javascript code that denies viewers of the website access to the right click functions. It works perfectly in Internet Explorer but when you view the website in Google Chrome you are able to right click and copy, etc. Why is that? Am I missing something in the coding or is it something else?

First the code:
Code:
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.

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.

The following function works fine. I was just wondering if there are any serious negatives to using so many parent, sibling and children type functions?

How to make html consistently see js functions. Let's say I have two functions in my javascript code. I want to move between the functions using html links or image maps, e.g. I want to trigger a certain function when clicking on a certain part of an image.
The problem is that when I start the function via "javascript:function" and then I want to trigger another function in the same way, I get an error message saying the function is not defined.
Below is a simple code illustrating what I mean:

My javascript quits working when I am rendering the html? (It works perfectly fine if the page is opened from http address directly). I did some research and concluded that "JavaScript is executed on page load", so when I render my html, my JavaScript functions are not automatically called.how should I call the javascript functions manually?
verify.html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

The above is a simplified example of the problem I'm facing. I could merge functions into one big self-referencing function (i.e. recursive function), but that's ugly and causes other problems (such as when insert form elements and wanting to harvest the user input afterwards). I considered declaring a variable in the top ".ready" function, and have all child functions stuff their HTML changes in it, but that seems to be a pain to keep track of and removes much of the value of using jQuery in the first place...
Is there a nice solution for this? To, after inserting HTML, somehow update the HTML state referred to by jQuery in the non-local scope(s)?

I've made this javascript portion to a site for a company that I am working for and I'd like to use it to fill in a form on another part of the website. Unfortunately we bought the rest of the website from basically like a web template company so they wont let us change the script on that actual page. Is there anyway that I can take my info from my javascript page, then use it to fill in the info on the other page without actually editing the html of that page?
