How to use PHP variable in a JQuery script

Question

I found some similar questions but I couldnt figure out :(

This is my jQuery:

<script>
function avukat_change()
{
        if (jQuery("#AVUKATNO").val()=='14')
            jQuery("#fieldatamatarihi").show(1000);  
        else  
            jQuery("#fieldatamatarihi").hide(1000);
}

And I would like to replace '14' with this:

$UserID = scf_user_userid()

where is `scf_user_userid()` defined? Can you run it in the same file or it is somewhere on the server-side. — d.raev, Apr 09 '14 at 10:01
You have three ways to do it: 1. Make webserver to pass .js files to PHP for parsing (not good idea). 2. Embed a small script in the .php file where you could define JS variables with values of PHP variables `var x = '';` and then call `func(x)` from JS file. 3. Make AJAX calls to request data from the server as @moonwave99 said (HTTP + JSON). I always bet on 3. where it is acceptable and use 2. for small tasks. — Rolice, Apr 09 '14 at 10:04
It defined in the same file. And problem is solved. Thanks guys. — cvdogan, Apr 09 '14 at 10:10

This should do:

function avukat_change()
{
    if (jQuery("#AVUKATNO").val()=='<? echo scf_user_userid();?>') 
       jQuery("#fieldatamatarihi").show(1000); 
    else  
       jQuery("#fieldatamatarihi").hide(1000);
}

missing ' ' around the php script like this: `''` – csharpwinphonexaml Apr 09 '14 at 10:08

Or a quicker solution would be to do it shorthand.

<script>
function avukat_change()
{
    if (jQuery("#AVUKATNO").val()=='<?=scf_user_userid()?>') 
       jQuery("#fieldatamatarihi").show(1000); 
    else  
       jQuery("#fieldatamatarihi").hide(1000);
}
</script>
