从PHP获取变量设置Javascript变量

Question

I have a page which I have collected two variables, I want to pass these variables to my document ready function. but for some reason.. My alerts for testing are just outputting the line code rather than the result.

just to note the JS script is in another file which is linked to the page.

PHP

<?php 

$cardid = test;
$custid = test;

?>

Javascript

$(document).ready(function(){

   var custid = '<?php echo($custid); ?>';
   var cardid = '<?php echo($cardid); ?>';

   alert(custid);
   alert(cardid);
});

Answer 1

Put your javascript code into a separate php file under script tag:

<script>

    $(document).ready(function(){

       var custid = '<?php echo($custid); ?>';
       var cardid = '<?php echo($cardid); ?>';

       alert(custid);
       alert(cardid);
   })

</script>

Include this file in your main php file (using the include function). It is not possible to execute php in a separate .js file.
