Huh? A hidden variable? Can you be more specific? What are you trying to accomplish?

brothercake · 11-27-2002, 05:38 PM

perhaps he's talking about passing data through query strings

Yes, that seems to make sense with the vocabulary he used. If that's the case, phani, you can use this function I wrote to extract all the GET parameters into an associative array

Code:

function parseGetVars() {
	var getVars = new Array();
	var qString = top.location.search.substring(1);
	var pairs = qString.split("&");
	var nameVal, val;
	for (var i=0; i<pairs.length; i++) {
		nameVal = pairs[i].split("=");
		val = (typeof nameVal[1] == 'undefined') ? '' : unescape(nameVal[1]);
		getVars[unescape(nameVal[0])] = val;
		}
	return getVars;
	}
var _GET = parseGetVars();

Of course, you can use any variable you like, I just chose _GET because it closely mimics the PHP counterpart.

if you don´t open the second page from the first one, use cookies. do a search in this forum for "cookies" it should return "some" results

...or use window.name if you are not using frames/iframes

set it in a page:
window.name="blah";

you can access it in another page even if it is not opened from the page where you set the window.name:

alert(window.name)
