Hi Chris,
change it to that:
jQuery.query = function(s) {
var r = {};
var q = s.substring(s.indexOf('?') + 1); // remove everything up to
the ?
q = q.replace(/\&$/, ''); // remove the trailing &
jQuery.each(q.split('&'), function() {
var splitted = this.split('=');
var key = splitted[0];
var val = splitted[1];
// convert floats
if (/^[0-9.]+$/.test(val)) val = parseFloat(val);
// ignore empty values
if (typeof val == 'number' || val.length > 0) r[key] = val;
});
return r;
};
Usage:
var query = $.query( $(this).attr("href") );
or
var query = $.query( location.search );
var certainParam = query.nameOfParam;
I also fixed that if a parameter is 0 (like number=0) it is converted to
a float and then evaluates to false in the next line, so that it won't
be put into the params hash map.
I think converting booleans makes sense as well, what do you think?
Heres a demo:
