The code of checkLogin is copied, it should be correct, but I don’t know what went wrong, and there is no response when I click the submit button

public function checkLogin(Request $request)

{

//Initial return parameters

$status =0;

$result ='';

$data = $request -> param();

//Create validation rules

$rule=[

'name|Username'=>'require', //Username is required

'password|password'=>'require', //Password is required

'verify|Verification code'=>'require|captcha', //Username is required

];

//Customized verification failure prompt message

$msg=[

'name'=>['require'=>'User The name cannot be empty, please check'],

'password'=>['require'=>'The password cannot be empty, please check'],

'verify'= & gt; [

'request' = & gt; '' verification code cannot be empty, please check ',

if($result===true){

//Construct query conditions

$map =[

                                                                                                                                                                                                                                                                                                 ];

## //Query user information

$user=UserModel::get($map);

if($user == null){

              $result = 'The user was not found';               }else{

<div class="formControls col-xs-8 col-xs-offset-3">

<input name="" type="button" id="login" class= "btn btn-success radius size-L" value=" Login    Record ">

</div>

<! -- Ajax submission script-->

<script>

$(function(){

//Add a click event to the login button

$("#login").on('click',function(event){

$.ajax({

type:"POST".//The submission method is post

url:"{:url('checkLogin')}",//Set the address of the script file for submitting data processing

data:$("form").serialize(),/ /Serialize the data of the current form and submit it

success: function(data){ //Only the flag bit is 1 before processing

if(data.status==1){

alert(data.message);

alert(data.message);
