Calling Parent Page JavaScript Function In An Iframe

Question

I am using an iFrame in my application. Let me give an example here. I have main page as

<html>
  <head>
    <script src='jquery.js'></script>
    <script>
      function TestFunction()
      {
        var FirstName = $("#first_name").val();
        alert(FirstName);
      }
    </script>
  <head>
  <body>
    Enter First Name: <input type='text' size='20' id='first_name'><br />
    <input type='button' value='Cilck' onclick='TestFunction();'><br />
    <iframe id='test_iframe' src='test_iframe.htm' height='200' width='200'>
    </iframe>
  </body>
</html>

...and this works fine with alerting whatever is entered in textbox

But is it possible to invoke the same function in iframe that will alert the value present in textbox of the parent page?

Suppose test_iframe.htm code is like this

<html>
  <head>
  <script src='jquery.js'></script>
  <script>
     function IframeFunction()
     {
        TestFunction(); // I know this wont work.. just an example
     }
  </script>
  <head>
  <body>
    <input type='button' value='Click' onclick='IframeFunction();'>
  </body>
</html>

Can this be done ?

I believe this can be done with 'parent'

function IframeFunction() 
{ 
   parent.TestFunction(); 
}

<html>

     {
       parent.TestFunction();  // or top.TestFunction()
     }
  </script>
  <head>
  <body>
    <input type='button' value='Click' onclick='IframeFunction();'>

<a onclick="parent.abc();" href="#" >Call Me </a>

See Window.Parent

Returns a reference to the parent of the current window or subframe.

If a window does not have a parent, its parent property is a reference to itself.

When a window is loaded in an , , or , its parent is the window with the element embedding the window.
