Adding variables into a javascript .js file?

Can I add values into a Javascript file like the example below?

/javascript.js?a=whatever&b=whatever

Then get them with '+a+' and '+b+'

Is it ok to do that?

Thanks for your help!

 

no. you cant.

but you can add variables to a php script. rename your js to .php, then have:
/javascript.php?a=whatever&b=whatever

and within the file, just iterate $_GET or do absolute varnames like

var a = '<?=$_GET['a']?>', b = '<?=$_GET['b']?>;

hth

 

That's a good idea, thanks!

Well technically you can, just loop through the script elements and check the src.

 

ah cool idea also.

 

Actually, you can.

function gup( name )
{
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return results[1];
}

Code (markup):

The function above will return the value of an URL parameter.
Usage example:

gup('hello'); // This returns 'world' from http://domain/page.php?hello=world

Code (markup):

taken from: http://www.netlobo.com/url_query_string_javascript.html

 

this is not correct- it will get parameters to the page that EMBEDS the js, not params to the js itself. different problem altogether.

 

Awful code, I hate it when people use regular expressions instead of parsing a string which is usually much easier. Also you have to call decodeURIComponent on the string.
