Run script in ajax

Question

can i run a java script in ajax? I've tried to embed some java script on the php that was triggered by an ajax command, the script is intended to change html attribute in the parent page. it doesn't work, when i look at the console in firebug it only print the script and doesn't even make an alert.

tnx so much for the rplies.

Feel free to include some code that you've tried but isn't working. — Kon

You need to evaluate the response text.

E.G. returning alert('foobar') in the ajax, you can then do eval(ajaxResponseText).

using a library like Prototype.js you can tell it to automatically evaluate script tags within the response text.

in the process.php, i will query some value, definitely an avatart; the holder of the queried data is $myavatar.., $myavatar = quried_avatar;

Doing such thing is considered very bad practice, you really better avoid it.

Instead of having the PHP send raw JS code, have it send "command" or "data" then parse this in the AJAX callback.

For example if you want to show alert have the PHP send only the text to appear in the alert, then in the AJAX callback take this value and do:

alert(ajaxResponse);
