Question

The client website needs to do a cross-domain JQuery Ajax call to a php file on my server, the php file will query the database for a bunch of stored javascripts which then need to be sent back to the client and be executed on the client’s website. This is what i have so far, haven’t done the grabbing javascript from database yet and it works. Is this the best way to do this (assuming i can grab the javascripts directly from the database without adding the escape sequence when echo’ing back to the client)? Thanks.

This is what i have so far:

 client side:
      $.ajax({ url: "http://localhost:8888/test.php",
      dataType: "script",
      });

 server side (test.php):
      <?php
      echo "alert(\"WORKS!\");";
      ?>

Answer 1

Review the ajax documentation and handle the success callback option on the ajax method:

$.ajax({
    url: "http://localhost:8888/test.php",
    dataType: "html",
    success : function(data) { alert(data); }
});

As noted by Ricardo, your PHP script should echo HTML or some other content appropriate for your scenario.
