Hi friends,
I need to send a value to a iframe, The iframe is present within the current window. How can i achieve this? I need to do with in javascript of the parent(current) window.
A:
Have a look at the link below, which suggests it is possible to alter the contents of an iFrame within your page with Javascript, although you are most likely to run into a few cross browser issues. If you can do this you can use the javascript in your page to add hidden dom elements to the iFrame containing your values, which the iFrame can read. Accessing the document inside an iFrame

A:
Use the frames collection.
From the link:
var frames = window.frames; // or // var frames = window.parent.frames;
for (var i = 0; i < frames.length; i++) {
// do something with each subframe as frames[i]
frames[i].document.body.style.background = "red";
}
If the iframe has a name you may also do the following:
window.frames['ponies'].number_of_ponies = 7;
You can only do this if the two pages are served from the same domain.

Bonus points for using ponies.

Depends on your specific situation, but if the iframe can be deployed after the rest of the page's loading, you can simply use a query string, a la:
<iframe src="some_page.html?somedata=5&more=bacon"></iframe>
And then somewhere in some_page.html:
<script>
var params = location.href.split('?')[1].split('&');
data = {};
for (x in params)
{
data[params[x].split('=')[0]] = params[x].split('=')[1];
}
</script>

A:
First, you need to understand that you have two documents: The frame and the container (which contains the frame).
The main obstacle with manipulating the frame from the container is that the frame loads asynchronously. You can't simply access it any time, you must know when it has finished loading. So you need a trick. The usual solution is to use window.parent in the frame to get "up" (into the document which contains the iframe tag).
Now you can any method in the container document. This method can manipulate the frame (for example call some JavaScript in the frame with the parameters you need). To know when to call the method, you have two options:
Call it from body.onload of the frame.
Put a script element as the last thing into the HTML content of the frame where you call the method of the container (left as an exercise for the reader).
So the frame looks like this:
<script>
function init() { window.parent.setUpFrame(); return true; }
function yourMethod(arg) { ... }
</script>
<body onload="init();">...</body>
And the container like this:
<script>
function setUpFrame() {
var frame = window.frames['frame-id'];
frame.yourMethod('hello');
}
</script>
<body><iframe name="frame-id" src="..."></iframe></body>
