Question

JS

var postData = $("#signUpMenu-form :input").serializeArray();
postData = JSON.stringify(postData);

$.ajax({
  type: "POST",
  url: "/main/class/classregister.php",
  data: postData,
  cache: false,
  processData: false,
  contentType: false,
  success:function(data){
    console.log(data);
    console.log("suceess");
  },
  error: function(jqXHR, textStatus, errorThrown){}
});

PHP

$data = json_decode(stripslashes($_POST['postData']),true);
print_r($data);

我正在尝试使用serializeArray将表单输入数据发送到php并获取数据，但不知何故我无法将数据返回到ajax。

我的代码出了什么问题？

您的ajax配置完全错误，无需对数据进行字符串化

var postData = $("#signUpMenu-form :input").serializeArray();

$.ajax({
  type: "POST",
  url: "/main/class/classregister.php",
  data: postData,
  dataType:'json',// adjust according to response type
  //cache: false, a POST can't be cached  
  success: function(data) {
    console.log(data);
    console.log("suceess");
  },
  error: function(jqXHR, textStatus, errorThrown) {

  }
});

然后在php

$data = $_POST;

echo json_encode($data);

serializeArray无法获取错误
