about combine ajax ,php and javascript -

-

i have main html file , using ajax call php file in same directory.

inside php file, call external javascript functions. javascripts functions not working. not possible?

i see generated source in web browser , normal. if call functions using php file (without using ajax), functions working , generated source same previous case. please me.

in html file using ajax follows:

xmlhttp.open("get","end_location_drop_down.php?q="+str,true); xmlhttp.send();

in php file functions follow,

<?php  echo '<script type="text/javascript" src="../js/pointing.js"></script>'; //external script      $btn8="'btn8'";     $q=$_get["q"];         echo '<script type="text/javascript">    nextpoint('.$at_id.'); //$at_id mean variable,nextpoint() java script function    </script>'; ?>

in javascript function have image swapping functions.they can call nextpoint(). didn't work.

javascript functions executed when load page directly in browser, browser 1 interprets , executes javascript code. when javascript code in different page , page being called through ajax, there no browser execute javascript code before ajax response sent you. won't work.
