Ttrack Changes In Content On Html Page After It Loaded?
May 11, 2009
I'm wracking my brain on this one.
After a html document loads in a browser,I want to be able to monitor
the page incase any content on it changes for any reason.
Is there a Javascript function with which I can track 'what has
changed' on the webpage .
This should be irrespective of the type of content on the html page
I have two example for you to ponder on:
Ex1:
-----
Say in an html document there are two select boxes s1 and s2.
The items list in s2 depends on selctions in s1 (page is not
refreshed..ie.. s2 is loaded through Ajax or sumthing)
So after the html page loads I need to get a notification whenever s2
is populated...
Ex2:
-------
Say ,in a html page,there's a link,Onclicking which a light pop-up
div is created with some text.
How can I capture the content of this dynamic pop-up?
In all this discussion,I'm not taking into account any particular
format of html...the html content can be anything.......I just need
to keep tracking if any content chages after the page loads...
Ideally I need to achieve this using javascript (client side
scripting)
How can I achieve this??

I'm building a tree control that lazily loads branches of the tree
using the document.load() method.
The external XML document that is loaded is generated by a servlet as
XHTML. What I would like to do is to add the new tree branch to the
correct place in the document in the browser window using the innerHTML
property of the parent node.
The relevant code snippet that I've written to do this is:
var target = document.getElementById(parentId);
target.innerHTML = xmlDoc.documentElement.xml;
This doesn't work, furthermore looking at the W3C DOM API it would seem
that the document.xml property is a Microsort proprietary extension
which makes it unsuitable for my application.

The project I am working on involves a flash piece that communicates with a iframe.Currently the flash piece just calls on javascript functions. I want the buttons in the flash piece to be able to change the src of the iframe.
<script type="text/javascript">
document.getElementById('video').setAttribute('src',address2);
function closeVideo() {
[code]....

I am working on a page that will load in other pages using AJAX and the .html method. Something like this :
<span id = "edit">Edit</span>
<div id = "cont">
</div>
//the click edit script
[Code]....
Unfortunately this does not seem to work, entirely. It does trigger the click event but it messes up the post for some reason. I have played around with it for the last 45 minutes or so and it seems like the click event trigger is what is messing things up, if I comment it out it works fine. Could anyone tell me why they think this is? note this is an over simplified version of my actual code, but the structure is the same.

On my webpage, I dynamically create an iFrame when a button is pressed, then load a html page from within my own domain into the iframe, based on what html page is loaded into a variable. My question is, can I dynamically change the font family of the loaded html page from the javascript of the main page? My code to create the iframe is:
function setSubTxt(){
var par = document.getElementById('parentDiv');
par.innerHTML = '<iframe src="'+subTxt+'" style="width: 375px; position: fixed; height: 365px; left: 400px; top: 145px; border=none;" name="subIframe" frameBorder=0></iframe>';
frames['subIframe'].window.location=subTxt;
document.subIframe.document.body.style.fontFamily = "Arial";
[Code]....
the variable "subTxt" has the url of the html page to be loaded (always on the same domain). The code: document.subIframe.document.body.style.fontFamily = "Arial"; was my attempt to dynamically change the font, but it didn't work. Also, it should be noted that there is no font family set in the html pages which would override this.

I'm trying to add dynamically generated HTML after the page has loaded. I've tried two versions.The latest versions is this, using insertBefore (as appendChild is buggy in a few browsers according to the SitePoint reference) ...
Code:
addImageField: function(x) {
var newNode = createImageField(x);
var src = document.getElementById("imageUploads");
[code]...
The first alert returns: object HTMLFieldsetElement .The second alert returns: object HTMLDivElement....and the third alert fails to fire, indicating a problem with the code above.Note that if I change the problem line to remove the null reference it still doesn't work (again the third alert won't fire):
Code:
scr.parentNode.insertBefore(newNode,src);

I was wondering if there was an easy way to dump the html that gets generated after the page gets loaded to verify it's what I wanted and expected (I'd like to check out the source, not just the results).

I have a page that inserts a div after another div on my page. Basically this div and its content are generated by the server and outputted via Ajax when the user clicks a button.I have something like:
//Listener function
$("div").click( function () {
alert("thing");
});
Clicking any of the divs that were loaded on the page will give this alert however, clicking on this div that was inserted after the user clicks a button does not respond to this listener. I put my rendered html into the w3c validator and my page has no errors (because I thought that maybe I had a missing end tag which would cause jquery to not work).

Try this out on any of your page...
And put this inside testing.html:
Try to click the button#btn 3 times... you will find the loaded testing.html will only run the script 2 times.. then it will show no script for the rest....
I tried it on chrome, firefox.
Trying to make a full ajax site may have alternative way to load and remove?

I'm incharge of updating the stats on a chl hockey teams Web Site. I
would like to know if there is a way (javascript) to be able to save
the content of the CHL Statistics WebPage on our Server with
Javascript, in a txt file.
If it possible, then I would take the content of that page. Execute
another script that will take this information an place it in our
database on our server. By doing this, our Team WebSite would be
update automaticaly.
At this time, I have to open the CHL Statistics WebPage. Then Save the
HTML page as a txt file, upload it on our server via FTP, then execute
my script that places it in our database.
Could you send your suggestions to rene.aube@gnb.ca?

I'm using an HTML page with one section having editable content. Nothing overly complicated. All other execCommands are working fine, but I cannot get Paste to work. The function is called from this button:
And, here's the Javascript function:
When I use the Copy or Cut buttons the selected text is loaded into the clipboard. If I press Ctrl+V to paste, it works fine. But clicking the Paste button either has no visible effect (if no text is selected) or just deletes any selected text. I've used the Paste command before from VB without any problem, but it's been awhile since I've used JS.

I have about 10 JQuery Books and they all talk about using Ajax(JQuery Load function) to insert either an HTML page or fragments of an HTML page into another page.
However, amazingly none of these books mentioned getting multiple items using the same function(document.ready).
Here is what I mean. I have a document.ready function which I use to get specific content from a page. However, to get additional items, I need to set up additional document.ready function.
So if I was retrieving 3 sets of content from a page, I will set up my script like this:
Code:
And the HTML
Code:
Is there a leaner better way to do this? Again all the books tells you how to grab a content, which I have done but do I have to create a new function for each item?

I have an ajax based page, which loads content from external page (html +js) So if i have a div "update_div" being updated with external content (html+js)
Let me be more specifig
Step1: Ajax content along with js loaded into update_div from a.html
Step2: Ajax content along with js loaded into update_div from b.html
What happens to the js loaded from a.html? Is it lurking in the memory or automatically/magically removed from the browser memory? I am afraid of memory leaks, if the js is still lurking in memory, the more ajax calls made, the more js is going to be held up in memory. Unless am totally wrong; i have no idea of the mechanism happening.

I'm creating a site that uses AJAX to create a "page flipping" type effect. So it works kind of like an FRAME, where when links, etc. are clicked just the main content area is reloaded using JQuery AJAX.
The problem is that that content seems not to pick up the CSS stylesheet rules. I have to press refresh before it loads the styles.

I have a script that takes longer to load than the page, so I would like to have it say "Loading - please wait!" until the script has loaded. I don't want it to hide the entire page - just this one script.Up until recently, I had no idea as to what ajax was, or what it did, so I surely am unable to do this.

I'm trying to bind an event handler to a button in a page loaded via Ajax. This procedure should apply to every page I have to load via Ajax. I have tried two things: first, I declared the 'click' event handler for the button like this, and just did my ajax request. Here's the code:
$("#close_button").click(function(){
alert("This should popup");
});
$.ajax({
url: 'js/ajax/text.html',

For starters i'm new to jquery and javascript, hence my post here. I've tried to do research but I'm not finding the answers. Here is the problem. the web page i'm working on has 2 area's or panes. one that changes dynamically via ajax and one that stays the same to control the dynamic area. The dynamic content is loaded with the following function to load a given page into the <div>.
[Code]...
When the content is loaded into the div jquery does not work. More specifically i'm using the jquery ui datepicker. The page that is loaded via loadPage() work fine if its not called by the function. but once it is it seems all javascript does not function.

I load content from a separate php page into a div in my other page. This is done using .Get I believe.I've taken the plugin from net tuts +This is working, however, plugins that are supposed to work with the content that's just arrived aren't. Only when specifying that page and loading that as a whole. Long version:I'm doing a website that's pretty graphics intensive. It's more like an application really, only with very "scarse" interface. So I liked the idea of loading only the new content directly onto the already loaded page instead of reloading everything.
And so I found a plugin from net tuts that did the very same thing.Basically, this plugin lets you load content from a said div container directly as a feed onto the page that's already loaded. So all pages are the same, with the only change being in the same div container as all pages have.Now, several issues occurred. What I find strange(probably not for you) is the fact that plugins that I use somehow stop working when loading the content using the said plugin. Cufon stopped working on the newly arrived content. And the same thing happens with a slide menu plugin as well that also arrives with the new content. But if I completely load the page that contains the div with Cufon and the slide menu, everything works as normal. But as soon as I click a link and new content arrives, plugins in that content does not work.
What am I missing? The pages are completely identical, with only a few differences in the a div container that both pages have. Clicking links are supposed to only remove existing content, fetch new content and place it in exactly the same location. One would think that scripts that are already loading in <head> would work with the newly arrived content as well?
