Matching a string using a javascript regex

I have the following string:

name=cvbb&source=Mamma+Mia&startdate=2014-03-24

The following regex matches till startdate

(source=.*(startdate))

How do I match the string till the '&' after Mia?

UPDATE:

name=cvbb&source=Mamma+Mia&startdate=2014-03-24&date=2014-04-24

I want the match to occur until the occurrence of the & right after Mia

Use the regexp /.*&/ will match till the last &.

Updated regexp:

/name=.*&source=[^&]*/

will give name=cvbb&source=Mamma+Mia if the string begins with name and source follows after it.

javascript object

Javascript:

See live demo: FIDDLE

function params_match(string) {
    var rx = /([^=]+)=([^&]+)&?/g;
    var matches = {};
    var match;
    while (match = rx.exec(string)) {
        matches[match[1]] = match[2];
    }
    return matches;
}

var st = 'name=cvbb&source=Mamma+Mia&startdate=2014-03-24';
var obj = params_match(st);
//{name: "cvbb", source: "Mamma+Mia", startdate: "2014-03-24"}

Inspired by this answer: https://stackoverflow.com/a/14210948/1076207

Regex:

See here: http://rubular.com/r/E6Wuejs0bA

/([^=]+)=([^&]+)&?/

# Match 1
# 1.    name
# 2.    cvbb
#
# Match 2
# 1.    source
# 2.    Mamma+Mia
#
# Match 3
# 1.    startdate
# 2.    2014-03-24

Since you are planning to parse the data later, I would recommend getting a key-value pair data, like this

var data = "name=cvbb&source=Mamma+Mia&startdate=2014-03-24";
console.log(data.split("&").reduce(function(result, currentItem) {
    var splitted = currentItem.split("=");
    result[splitted[0]] = splitted[1];
    return result;
}, {}));

Output

{ name: 'cvbb', source: 'Mamma+Mia', startdate: '2014-03-24' }

If you want to ignore startdate alone, then you can include a condition like this

    var splitted = currentItem.split("=");
    if (splitted[0] !== "startdate") {
        result[splitted[0]] = splitted[1];
    }
    return result;

Then the result will be

{ name: 'cvbb', source: 'Mamma+Mia' }

Assuming these things are always in the same order, (name=.*&) ought to do it.
