PHP は、ajax に基づいてすべてのバックグラウンド関数呼び出しの制御を実装します。

$('#submit').on('click', function (e) {
    e.stopPropagation();
    $.ajax({
      url: "../../controllers/Controller.php",
      data: {
        action: "LoginController/login",
        username: username,
        password: password
      },
      dataType: "text",
      type: 'POST',
      timeout: 10000,
      error: function () {
        alert("服务器超时");
      },
      success: function (data) {
          alert(data);
      }
    });
  });

<?php

if (!empty($_REQUEST[&#39;action&#39;])) {
  try {
    $action = explode(&#39;/&#39;, $_REQUEST[&#39;action&#39;]);
    $class_name = $action[0];
    $method_name = $action[1];
    require $class_name . &#39;.php&#39;;
    $class = new ReflectionClass($class_name);
    if (class_exists($class_name)) {
      if ($class->hasMethod($method_name)) {
        $func = $class->getmethod($method_name);
        $instance = $class->newInstance();
        $func->invokeArgs($instance, array($_REQUEST));
        $result = $instance->getResult();
        echo $result;
      }
    }
  } catch (Exception $exc) {
    echo $exc->getTraceAsString();
  }
}
?>

<?php
class LoginController {
　　
  private $result;
  function LoginController() {
    //初始化数据库连接等参数
  }
  function login($args) {
    //具体的登录逻辑
  }
  function getResult() {
    return $this->result;
