2016 System design Phase I (archive i) jQuery Ajax serialize () method form submit data

JQuery Ajax Serialize () method form submits data, there is a very strange problem, it seems that can not be taken to hide the value of the control.

 //Click the Submit button to save the data$ (' #btn_submitUser '). Click (function () {            varUserId = $ (' #UserId '). Val (); if(UserId = = ""{$.ajax ({type:"POST", URL:'/users/create/', Data: $ ("#SaveUserForm"). Serialize (), DataType:"JSON", Success:function(data) {if(Data. UserId > 0) {}}, Beforesend:function() {}, complete:function () {                    }                }); } Else{$.ajax ({type:"POST", URL:'/users/edit/', Data: $ ("#SaveUserForm"). Serialize (), DataType:"JSON", Success:function(data) {if(Data. UserId > 0) {}}, Beforesend:function() {}, complete:function () {                    }                }); }        });
