Accessing Iframe DOM Elements
Feb 19, 2010
I need to pull data from an iframe, everything is on my domain (no cross-domain issues). This is how the iframe is named.
Code: <iframe ID="search_frame" src="http://www.mysite.com/pnsearch.php"></iframe>
The iframe has a bunch of <span> elements in it. I need to access the innerHTML of the spans, to check for data and use the data elsewhere. Each span has an unique ID assigned to it. What would be the syntax to read this information? I've tried all sorts of document.frames["search_frame"].getElementById("ID").innerHTML variations to no avail.

I call a javascript function in my page load that accesses an iframe and I get an error. But if I wait till the page completely loads and access the iframe through a click event
everything works fine.
I'm trying to set some of the iframe's properties on page load. Can I do this?

I have a situation where I'd like to read/parse the content
of a file I've read into an <IFRAME>. I've looked through
various FAQs and searched forums, and the closest I get to
accessing the file content is
myIframe.contentWindow.document.body.innerHTML
where myIframe is the node from getElementById(). But while
I can see the content of the file on my web page, I get an
empty string from the above reference. How do I get to the
file?

Is it possible to access javascript variables in an iframe src page from the parent page, or vice versa. How do you do this? What about the DOM?

Firstly, I am aware of all the issues that are introduced with frame
pages - this was not my decision - it is just what I have to work
with...
I have a frame page that looks like this
-------------------
| topFrame |
-------------------
| navFrame |
-------------------
| ContentsFrame |
|------------------
Within the contents frame I have a NEW FRAME set which looks like this
--------------------
| | |
|treeFrm | frmDisp |
| | |
--------------------
I know that this is awful. I have a link in the contentsFrame. When I
move over that link, I need to get a layer that already exists in the
frmDisplay to become visible..

When are named elements written with script accessible to script?
<html><head><script type="text/javascript">
function ready() {
alert( document.getElementsByName("div").length );
}
</script></head>
<body onload="ready()">
<script type="text/javascript">
document.open();
document.writeln( "<div name="div"></div>" );
document.close();
</script>
</body></html>
IOW, why are there 0 elements named div at the time the <body>
element's onload handler is invoked? When can I retrieve this named
div from the document hierarchy?
This exercise is necessary since code I have written using the DOM
(that works) has to run on God-forsaken browsers such as IE 5.1 for
Mac whose support for the DOM is spotty at best.

However, I'm still wondering about my actual problem, which is that I need to initialize some arrays of named elements when the document is loaded so they can be used by other functions used as event handlers. What I have now is that every function that requires
these arrays checks to see whether they have been initialized, and if not initializes them. That seems to be a fairly ugly hack, and I'd like to use a better way if it exists. Does that make sense?

I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?
for(var i = 0; i < tables.length; i ++)
{
var newDiv = document.createElement("div");
newDiv.setAttribute("id", tables[i].name);
newDiv.setAttribute("name", tables[i].name);
newDiv.setAttribute("class", "hidden");
[Code]...

I have a problem in accessing all elements with a common id name in ExtJs. In fact, I have a couple of divs with id like:divmic+a number.
That is the code:
Code:
<div id="slideshow" >
<%
for i=0 to 660/23
for j=0 to 380/23
Response.Write "<div id=divmic" & i & j & "
[Code]...
If I try this code, what is inside of "each" instruction works, but if I want to access all those elements having id starts with "divmic", it doesn' work. Why it's happen that think and how to put all those elements into an array, in ExtJs ?

I'm having trouble accessing some Elements with jQuery after I created them and added them to the HTML. I want to add some Checkboxes to my Site as soon as the user clicks another Checkbox. That works just fine. But if the user clicks on one of these added checkboxes, i want an event to trigger, too. For starters, i just want to alert a message. But this doesnt happen.So, now I think the Elements are added properly to DOM tree. But still, when I click on one of the added input Elements, nothing happens.What am I doing wrong? How can i get jQuery to recognize the Elements I added?

I am trying to write a Greasemonkey script using jQuery to automate various processes on a web site. One of them involves automatically filling in a form located in a dynamically generated iframe. When the frame is generated I can do $('#NewFrame').length and get 1 confirming it is now available. However, when I do $('#NewFrame #TheForm').length I always get 0 even though I can clearly see the form there in the iframe.

I've written several utility pages that use a dynamically created
iframe. The iframe typically has a form that is populated by the main
page. Then the form is submitted to be processed, and the returning
page does something -- call a function on the main page, change a
variable on the main page, etc.
All this stuff I created works on IE. Sorry, didn't have other browsers
available to test. Now I have access to a machine with FF, and none of
these scripts work.
So, short and sweet: What is the proper way to reference a form on an
iframe from the parent doc in firefox? Also, call a function from the
parent to the iframe, and vice-versa, call a function on the parent doc
from the iframe when it loads?
