javascript - jQuery ajax 请求 : how to access sent data in success function?

Question

所以我正在努力实现以下目标，但我不知道如何实现。

$.ajax({
  url: "whatever.php",
  method: "POST",
  data: { myVar: "hello" },
  success: function(response) {
    console.log('received this response: '+response);
    console.log('the value of myVar was: '+data.myVar); // <<<< data.myVar is not accessible from here
    console.log('the value of myVar was: '+myVar); // <<<< myVar is not accessible from here
  }
});

有没有办法在 .success() 函数中访问 myVar 的值？我能否以某种方式在 .success() 函数中获取在此 ajax 请求中发送的原始 data 对象？

希望得到您的解决方案。谢谢!

Answer 1

您可以使用this 访问整个对象。所以你可以这样做:

$.ajax({
  url: "whatever.php",
  method: "POST",
  data: { myVar: "hello" },
  success: function(response) {
    console.log('received this response: '+response);
    console.log('the value of myVar was: '+this.data.myVar);
  }
});
