I am new to Ajax and am wondering if following is feasible:
I am using PHP to pull some html code from database on button click
and then displaying it on the page. If the html code is actually
javascript - it won't run. See below for example below.
If you run it as is, it will work and a javascript alert will show up.
If you remove the comments from the second $data= line, it won't run.
I'll get javascript error saying that the go() function is not
defined.
My question basically is - is it possible to call and run javascript
via Ajax like this?
Thanks.
<?
require("Sajax.php");
function display() {
$data = "<img src=\"://www.google.com/intl/en_ALL/images/logo.gif\"
onload=\"alert('img alert');\">";
// $data = "<script>function go(){alert('function
alert')};</script><img
src=\"://www.google.com/intl/en_ALL/images/logo.gif\"
onload=\"go();\">";
return $data;
}
sajax_init();
// $sajax_debug_mode = 1;
sajax_export("display");
sajax_handle_client_request();
?>
<html>
<head>
<title>Ajax</title>
<script>
<?
sajax_show_javascript();
?>
function do_display_cb(data) {
document.getElementById("data").innerHTML = data;
}
function do_display() {
x_display(do_display_cb);
}
</script>
</head>
<body>
<input type="button" name="check" value="Display"
onclick="do_display(); return false;">
<div id="data">
Data will appear here
</div>
</body>
</html> |
