Ask: Why can't the ajax submitted data be transmitted to the controller?

Question

I was studying "The latest ThinkPHP 5.1 world premiere video tutorial (60 days to become a PHP expert online ** class)" by teacher Peter.zhu

, in section "10-3 Preliminary Implementation of User Registration Function", why can't my ajax submission data be passed to the controller?

register.html code is:

##{include file="public:header" /}

{include file=&quo;

    <div class="form-group">

    <label for="inputEmail4" class="col-sm-2 control-label">密码：</label>

    <div class="col-sm-10">

      <input type="password" name="password" class="form-control" id="inputEmail4" 

placeholder="Password">

#%;

#<script type="text/javascript">

$(function(){

$('#register').on('click',function(){

//Submit user information using ajax

$.ajax({

type: 'post',

## url: "{:url('insert')}",

#%2

echo "<script type='text/javascript'>alert('insert was executed');</script>";

// echo "dfsdfsdf";

if(Request::isAjax()){

// Verify data

// $this->error("Request type error",'register');

$ data = Request::post();//Get the data to be verified

$rule = 'app\common\validate\User';//Customized

Answer 1

Why should data be login and not form?
