把location.search处理成一个对象

function parseUrlParams() {
    if (window.location.search.length <= 0) return false;
    var info = window.location.search.slice(1);
    var result = {};
    info.split('&').foreach(item => {
        result[decodeURIComponent(item.split('=')[0])] = decodeURIComponent(item.split('=')[1]);
    });
    return result;
}
