YII2框架中使用yii.js实现的post请求

 // html代码
 <?= Html::a(
   '删除',
   [
     'delete',
     'id' => $id,
   ],
   [
     'data' => [
       'confirm' => '你确定要删除吗？',
       'method' => 'post',
     ],
   ]
 )
 ?>
 // html代码

window.yii = (function ($) {
  var pub = {
    // 定义了处理事件的方法，比如下面这个：
    confirm: function (message, ok, cancel) {
      if (window.confirm(message)) {
        !ok || ok();
      } else {
        !cancel || cancel();
      }
    },


    handleAction: function ($e, event) {
      var $form = $e.attr('data-form') ? $('#' + $e.attr('data-form')) : $e.closest('form'),
      method = !$e.data('method') && $form ? $form.attr('method') : $e.data('method'),
