PHP operates entirely and then writes pure text (HTML+JS+CSS), with no PHP remaining. Then and only then does anything else (including JS) operate.
In other words, you simply cannot do this. You'll need to order it differently.

The easiest way is something like this:

var url = <?php echo $url1; ?>+jsvar+<?php echo $url2; ?>;

Thanks for the reply, can u help me in my case

var order = document.getElementById('list_filter').value;

<?php $name = order; ?>

he_list.ajax_url = '<?php echo $this->url(array('module' => 'hecore', 'controller' => 'index', 'action' => 'list','search' => $name )); ?>';

how can i separate into two url's. I need to replace 'order' value with '$name'. I am trying this for last 2 hours but unable to do it.

You can't. As I said in my last post, this is entirely impossible. You need to generate the URL in PHP in two parts and leave a blank space to insert the $name part in Javascript. You'll need to rewrite your class's url() method (function) to create two values, not one, and then to combine that with javascript to add in the JS 'name' variable. You cannot put the JS variable "into" PHP.

(The only way to do this is to use Ajax, and that's more complicated than you need here, because you can instead use JS to build the final URL.)

There's another alternative: you could use a dummy value for $name, like ###. Then use a Javascript string replacement function to search for "###" and replace it with whatever your JS 'name' variable's value is.
