1. Ajax is used in the project. As a result, during the test, it was found that the page performed differently in the two browsers: 360 Browser could successfully achieve the pop-up (alert) effect, but Firefox had no effect at all. But they all have one thing in common: no data is obtained under the network option xhr in the browser's debugging mode (F12), but data can be seen in all places on the network, html, css, and js, including index homepage (POST), other resources are obtained through GET.
2. Using the automatic verification function of ThinkPHP, the error will automatically return information, including no username or password entered, but I did not compare the account password, and I don’t know why the username and password in the 360 ??browser I randomly entered the password and found a blank alert dialog box. I don’t know what is going on?
When the alert dialog box appears in the 3.360 browser, xhr still has data, but when OK is clicked on the alert dialog box, the xhr data disappears.

The code is as follows:
(1) login.js

<code>//前端登錄業(yè)務(wù)類(lèi)
var login={
  checkUser:function(){
    //獲取登錄頁(yè)面中的輸入數(shù)據(jù)
    var userName=$('input[name="username"]').val();
    var userPass=$('input[name="userpass"]').val();
    //使用ajax
    var url="/stfjzd-15/index.php/Home/Index/checkUser";
    var data={"username":userName,"userpass":userPass};
    $.post(url,data,function(result){
      //$("#result").html(data.info).show();
      //$("#result").fadeOut(4000);
      if(result.status){
        alert(result.info);
      }else{
        //alert(2);
        alert(result.info);
      }
    },"json");
  }
}</code>

(2)IndexController.class.php

<code><?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
  public function index(){
    $this->display();
  }
  //用戶(hù)驗(yàn)證
  public function checkUser(){
    //接收變量，默認(rèn)htmlspecialchars過(guò)濾
    $userName=I("post.username");
    $userPass=I("post.userpass");
    $User=D("Stuser");
    //ThinkPHP的自動(dòng)驗(yàn)證必須使用create()才能啟用
    if(!$User->create()){
      return $this->error($User->getError());
      //exit($User->getError());
    }
  }
  //空操作
  public function _empty(){
    echo "頁(yè)面不存在，請(qǐng)檢查您輸入的路徑是否正確，我要返回<a href='"._PHP_FILE_."' alt='返回首頁(yè)' title='返回首頁(yè)'>首頁(yè)</a>";
  }
}</code>

(3)StuserModel.class.php

<code><?php
  namespace Home\Model;
  use Think\Model;
  //用戶(hù)表模型
  class StuserModel extends Model{
    //構(gòu)造函數(shù)創(chuàng)建模型
    public function __construct(){
      $this->DB=M("Stuser");
    }
    //ThinkPHP的表單自動(dòng)驗(yàn)證
    protected $_validate=array(
      array("username","require","用戶(hù)名不能為空"),
      array("userpass","require","密碼不能為空"),
    );

  }

Try using $this->ajaxReturn() or json_encode
