PHP, AJAX and JS

Matt_B · Mar 24, 2007

Anyone in here any good with AJAX?

Basically I have a main page, call it index.php, which has a JS function declared, call it Reload(depth,width).

I use AJAX to load a page, call it data.php?id=1

I get the AJAX page to run a DB query and echo "<script type=\"text/javascript\">Reload('" . $data["depthBedding"] . "','" . $data["trenchWidth"] . "');</script>";

For some reason this isn't running the Reload function declared in the main page. Any idea why?!?!

EDIT: It does echo the javascript content into the page correctly, it just doesn't run the function. Do I need to declare it global somehow?

Do you have something coded to call the function on the AJAX page?

Maybe something like <body onload="Reload()">

Nope, as the Ajax content is loaded into a div in the page you shouldn't use the <html> or <body> tags

Not sure I understand ya.

What I was getting at was that you need an event to trigger the function, for example the page loading.

Ajax loads the page content of the second page into a div, mine simply echos a javascript <script> tag that should trigger the Reload function. It doesn't throw an error saying "function cannot be found" which confuses me, because I would expect that if it couldn't find it.

For anyone in a similar quandry I figured it out. As it puts my new page content into a div, it clearly isn't going to run a script tag, as it trates it as content.

Doh

Yo, if you go here http://www.prototypejs.org/download and download the prototype.js file you can then run the javascript using the evalscripts function that the prototype.js file has

like this

xmlHttp.responseText.evalScripts()

This might help you out
