javascritp添加url参数方法

 

 

//将对象参数加入到url中,如果原来url中有则覆盖
function addToUrl(obj){
  var aprotocol = location.protocol;

    }
    return result;
  };

    var resObj = {};
    var arr = str.split('&');
    for(var i = 0; i < arr.length; i++){
      resObj[arr[0]] = arr[1];
    }
    return resObj;
  };
  var existObjKey = function(existObjKey_obj, str){
    for(var i in existObjKey_obj){

        return true;
      }

        result[i] = obj2[i];
      }else{
