js获取url中的参数对象、js生成带参数的url

 // 获取url中的参数，并返回一个对象
 $.getRequestData = function() {
     var url = location.search; //获取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;
 };

 // 生成一个带参数的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('&'));
