call javascript function from outside an iframe

Question

I have one entire html openning inside an iframe that contains a javascript function getData().Now I am not sure how to call getData() from outside that frame.Also is it pos

Answer 1

You can get a reference to the frame window object from the window.frames property. See https://developer.mozilla.org/en/DOM/window.frames

UPDATE:

You can access the global context of a named iframe with window[framename]. e.g:

Although you will need to make sure the iframe has loaded.

In jQuery you can use the contents method if you want access to the iframe DOM:

$("iframe").contents()

All this is assuming the frame hosted within the same domain.

UPDATE[2]:

You asked if it is possible to call the getData function from an external js file. The answer is yes (if I understand you correctly). Here is an example:

Then in the getdata.js file you have:

var dataFrame = window.data;

// when the frame has loaded then call getData()
dataFrame.onload = function () {
    var myData = dataFrame.getData();
    // do something with myData..
}

Hope this answers your question :)
