PHP in javascript

[rob323]

Hello all,
I'm extremely new to Javascript, and I realize that this is a PHP forum, but I was wondeirng if anyone knew how to use PHP inside a javascript decision structure, such as:

<SCRIPT language="JavaScript">
<!--
function go_there(id)
{
var where_to= confirm("Do you really want to go to this page??");
if (where_to== true)
{
</script>
<?php
echo "Hello World!";
?>
<script>
}
else
{
}
}
//-->
</SCRIPT>

but that doesn't work.
Sorry for a question that sort of tests the boundaried of the forum! Any input is greatly appreciated! Thanks so much!

I also tried a similar sort of thing today with a who is currently online feature for my game / forum... but it never worked. I would also appreciate any feedback for future use.

You can't simply close a SCRIPT tag. Besides, "Hello World!" isn't a valid Javascript command anyway.

What are you trying to do? You have to use Javascript functions in Javascript... not PHP functions...

Sorry for not being clear the first time, I'm trying to use PHP in my javascript function. I've tried closing the <script> tags, but that simply ends the function, and thus it doesn't work. Thanks for your input though! And sorry for not being clear the first time

Right, what I'm saying is that you simply can't close a SCRIPT tag like that. Think about it - this is what the browser sees:

<SCRIPT language="JavaScript">
<!--
function go_there(id)
{
var where_to= confirm("Do you really want to go to this page??");
if (where_to== true)
{
</script>Hello World!<script>
}
else
{
}
}
//-->
</SCRIPT>

Ok, that's understood. However, in PHP you can do stuff like that... regardless, is there any real way to solve this? Sorry if this sounded obnoxious

PHP is a server-side scripting language (which means it's parsed at the server, and then sent to the browser. JavaScript is client-side... It isn't parsed until the user performs a function to trigger the script... By that time, the PHP is already parsed and sent to the browser. You can't mix and match them.

Alright, so I think I'll try something like ajax. Thanks for all of your help and time!
