I'm working on a ancient project which is based on and tags.
Here's the common HTML structure of the parent page (index.html):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
</head>
<frameset rows="75px,*" frameborder="0">
<frame name="frame1" src="frames/frame1.html">
<frameset class="child_frameset">
<frame name="frame3" src="frames/frame3.html">
</frameset>
</frameset>
</html>
Here how I specify the javascript function on the child frame (frame3.html):
<!DOCTYPE html>
<html lang="en">
<head>
<script type="text/javascript">
function helloWorld(){
alert('hello world!');
}
</script>
</head>
<body>
<h1>I'm frame 3</h1>
</body>
</html>
My task is to call helloWorld() function. How do I do that?
Thanks in advance!

The JavaScript call() Method The call() method is a predefined JavaScript method. It can be used to invoke (call) a method with an owner object as an argument (parameter). With call() , an object can use a method belonging to another object.
Define a function named "myFunction", and make it display "Hello World!" in the <p> element. Hint: Use the function keyword to define the function (followed by a name, followed by parentheses). Place the code you want executed by the function, inside curly brackets. Then, call the function.
HTML frames are used to divide your browser window into multiple sections where each section can load a separate HTML document. A collection of frames in the browser window is known as a frameset. The window is divided into frames in a similar way the tables are organized: into rows and columns.
You can do it like this:
document.getElementById('frame3').contentWindow.helloWorld();
You can call method from childframe
window.frames[n].frames[m].methodName()
where n , m are integers starting from 0.If you have document only one frame remove the frames[m] part and get the job done.
Ya one more thing , do trial an error and find out exact frame numbers and method. Hope this helps
