js将url查询字符串转换为json数据

function query2Hash(queryStr) {
    var h = {};
    console.log(window.location.search);
    var qArr = (queryStr || window.location.search.replace(/\?/, '')).split('&');
    for (var i = 0,
    len = qArr.length; i < len; i += 1) {
        var kvArr = qArr[i].split('=');
        h[kvArr[0]] = kvArr[1];
    }
    return h;
}
