            1.先截取  'a=1&b=2&c=&d=xxx&e'
            2.拆分该字符串
            3.变成对象格式

       var newArr = newStr.split('&');//["a=1", "b=2", "c=", "d=xxx", "e"]
       var obj = {};

       for(var i=0;i<newArr.length;i++){
           var arrs = newArr[i].split('=');
           obj[arrs[0]] = arrs[1] || '';
       }

       console.log(obj);
