combining JavaScript and PHP

I have decleared a function by Javascript before body of my page:

Code:

<script type="text/javascript">

<!-- Hide the script

function warn_on_submit()

{

        var msg = "Are you sure, Dude????";

        if (confirm(msg))

                location.replace('update.php');

        else

                location.replace('java.php');>";

}

// end hiding -->

</script>

I have a form inside my PHP and I want to call my JavaScript function when onClick event is occured:

PHP Code:




print "<form method='POST' action='update.php' name='form1'>"; 
print "<input type='hidden' name='unique_id' value='{$unique_id}'>"; 
print "<input type='submit' value='update' onClick='warn_on_submit();'>"; 
print "</form>";

But when I submit the form I don't see any message asking for confirmation.

I am quite new to Javascript so excuse me if it was a stupid question

It is that extra >"; you have in your else statement.

thank you very much. I should have been more careful about that.
my new problem is that when I press ok or cancel i got to update.php and cancel button doesn't do anything in this page

If you're using Firefox, you can use its built-in Javascript console to help you spot things like this.

Assuming you've got it set up the way I have, you should find the Javascript console option in the tools menu; any JS errors will show up in there, with their line numbers and error message. It would probably have helped you a lot in this case.

Other browsers also have features that do the same thing, but Firefox is the best for debugging JS, IMHO.

Here is the error which is written in Javascript console of Firefox:

Error: Expected ':' but found '='. Declaration dropped.
Source File: http://mohi/change.php
Line: 0

Everything seems correct :(
