[removed].search query as JSON

Question

Is there a better way to convert a URL\'s location.search as an object? Maybe just more efficient or trimmed down? I\'m using jQuery, but pure JS can work too.

Answer 1

JSON Parse after stringify does the job of converting to a json with array data.

?key1=val1&key2[]=val2.1&key2[]=val2.2&key2[]=val2.3&

{
     'key1' : 'val1',
     'key2' : [ 'val2.1', 'val2.2', 'val2.3' ]
}

function QueryParamsToJSON() {            
    var list = location.search.slice(1).split('&'),
        result = {};

    list.forEach(function(keyval) {
        keyval = keyval.split('=');
        var key = keyval[0];
        if (/\[[0-9]*\]/.test(key) === true) {
            var pkey = key.split(/\[[0-9]*\]/)[0];
            if (typeof result[pkey] === 'undefined') {
                result[pkey] = [];
            }
            result[pkey].push(decodeURIComponent(keyval[1] || ''));
        } else {
            result[key] = decodeURIComponent(keyval[1] || '');
        }
    });

    return JSON.parse(JSON.stringify(result));
}

var query_string = QueryParamsToJSON();
