I meant a parameter like this: index.php?foo=bar&something=else
Here's a little helper to extract such parameters:
jQuery.query = function(s) {
var r = {};
if (s) {
var q = s.substring(s.indexOf('?') + 1); // remove everything
up to the ?
q = q.replace(/\&$/, ''); // remove the trailing &
jQuery.each(q.split('&'), function() {
var splitted = this.split('=');
var key = splitted[0];
var val = splitted[1];
// convert numbers
if (/^[0-9.]+$/.test(val)) val = parseFloat(val);
// convert booleans
if (val == 'true') val = true;
if (val == 'false') val = false;
// ignore empty values
if (typeof val == 'number' || typeof val == 'boolean' ||
val.length > 0) r[key] = val;
});
}
return r;
};
Usage:
var params = $.query( $('a').attr('href') ); // { foo: 'bar', something:
'else'}
alert(params.foo); // 'bar'
