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’
