How do I "include()" JavaScript files dynamically? (ala PHP)

[FireFly]

Hi,

In PHP you can do this:

$file = './foo.php';
include($file); 

Is it possible to do the same thing in JavaScript, without reloading the page, i.e:

var file = window.prompt('Please enter a file name:', '');
include(file);

Obviously include() isn't going to work, but is there some other function (or maybe it requires a lot of custom code) that will allow this?

Thanks,
Chen

Do you mean, into the HTML, or pull this in from a separate script file itself?

Why not just include your JS like so:

<script type="text/javascript" src="/myJSfile.js"></script>

Unless I'm misunderstanding something, this should be what you need.

Well, since Vinnie laid out the HTML method, I'll show you the script method

[b][color=black]function[/color][/b] addScript[b][color=navy]([/color][/b] src [b][color=#000000])[/color][/b]
[b][color=navy]{[/color][/b]
  [color=navy][b]var[/b][/color] s [color=blue]=[/color] [color=purple]document[/color].createElement[b][color=navy]([/color][/b] [color=red]'script'[/color] [b][color=navy])[/color][/b];
  s.setAttribute[b][color=navy]([/color][/b] [color=red]'type'[/color], [color=red]''[/color] [b][color=navy])[/color][/b];
  s.type [color=blue]=[/color] [color=red]'text/javascript'[/color];
  s.setAttribute[b][color=navy]([/color][/b] [color=red]'src'[/color], [color=red]''[/color] [b][color=navy])[/color][/b];
  s.src [color=blue]=[/color] src;
  [color=darkorange]// The above is the most verbose but most compatible way to add properties[/color]
  [color=purple]document[/color].getElementsByTagName[b][color=navy]([/color][/b] [color=red]'head'[/color] [b][color=navy])[/color][/b].[b][color=navy]item([/color][/b] [color=red]0[/color] [b][color=navy])[/color][/b].appendChild[color=navy][b]([/b][/color] s [b][color=navy])[/color][/b];
[b][color=navy]}[/color][/b]

Just to clarify, I can call addScript('foo.js') and the page will "require" foo.js, including any variables it may define, etc.?

At any rate, thank you very much for your assistance.

Yes, that is correct.
