Call a js with GET parameters

I need someone to enlighten me. I've seen this:

<script src="http://host.com/file.js?no_forms=1"></script>

What does that means? A GET parameter passed to a javascript file? Into which conditions this can be done? What kind of approach is this?

Any help would be appreciated.

Sometimes the parameter is used simply to prevent client side caching.

It could also be that requesting file.js is actually rewritten as a dynamic call (say script.php?file=file.js&no_forms=1) that is fetching the correct file and using the extra parameter somehow.

You can use this

<script src="http://host.com/file.js" no_forms="1"></script>

And

function $_GET(q,s) {
    s = s || window.location.search;
    var re = new RegExp('&'+q+'=([^&]*)','i');
    return (s=s.replace(/^\?/,'&').match(re)) ? s=s[1] : s='';
}

And get result

var noForms = $_GET('no_forms');

?no_forms=1 is just a query string parameters. i will just tell the common usage of such things.

  • Used for to avoid caching (get new updated version of JS)
  • Some sort of redirection
  • Even some application usage ideas.
