js獲取url中的參數對象、js生成帶參數的url

// 獲取url中的參數，並返回一個對象
$.getRequestData = function() {
    var url = location.search; //獲取url中"?"符后的字串
    var theRequest = {};
    if (url.indexOf("?") != -1) {
        var str = url.substr(1);
        strs = str.split("&");
        for (var i = 0; i < strs.length; i++) {
            theRequest[strs[i].split("=")[0]] = decodeURIComponent(strs[i].split("=")[1]);
        }
    }
    return theRequest;
};

// 生成一個帶參數的url
$.createUrl = function(obj) {
    var length = obj && obj.length,
        idx = 0,
        url = obj.url + '?';
    for (var key in obj) {
        if (key != 'url' && obj[key] !== null) {
            url += (key + '=' + encodeURIComponent(obj[key]) + '&');
        }
    }
    return url.substring(0, url.lastIndexOf('&'));
