Script not loading

Posted 25 June 2012 - 05:11 AM

Dear code dreamers, I have a php script called test.php that I want to call from another page on another server. I used a script tag in the calling html page like: 
<script type="text/javascript" src="http://www.example.com/test.php"></script>
Now the script is supposed to load an image like a banner ad but nothing happens when I load the calling page. However when put that link (http://www.example.com/test.php) directly into the browser it works perfectly. Does anybody know why that is? Is it because I said type="text/javascript"? Does it have to be javascript file like test.js? How do I call a php script like that? Thanks in advance.

what MIME type does test.php have? JS and CSS files explicitly require the correct MIME header otherwise it’s as if you were sending an HTML document.

From my experience, I think when executing javascript scripts, as you mentioned, it has to be test.js in the link.

nope, it doesn’t have to (based on personal experience, because I use PHP files for JS)

You can put: header('content-type: text/javascript'); at the top to ensure it's treated as javascript, and of course make sure the data printed/echoed out in the php file is in fact valid javascript.

Thank you all very much for you kind replies. So I basically have to add that line: header('content-type: text/javascript'); to test.php to make sure it is treated as javascript? Does the output of the script still have to be javascript or is html ok?

let me put it this way: if it is not strictly Javascript, you’ll get a parse error.

I am still failing to implement this properly. I have added that line: header('content-type: text/javascript'); to test.php and tried to make the output javascript by using 
document.write("<img src='images/testimage.jpg' width='160' height='600'/>";
Now this produces funny results as firefox is displaying that code exaclty as it is above and explorer is asking wether to open or save test.js? Can you please show me a small demonstration of how you would go about implementing this. I am not really good with javascript and therefore can not convert test.php to javascript .

examples are best: in http://kulturbeutel-.../main/this.html you’ll find js.php quite at the end of the <head>.

:withstupid: Thanks for that reference. I call mine the same way. But I do not understand the contents of js.php, what I want to see is a demonstration inside of js.php on how to output the javascript code using echo. Apologies and lots of thanks in advance.
