“辍学:学生未定义

$.ajax({
    url: "student_info.php",
    method: "post",
    data: {
      studentId: student_id
    },
    success: function (data, status) {
      console.log(studentId);
    },
  });

<代码>console.log应显示价值0001。

Answer 1

学生如果学生想要获得学生补贴,你可以使用学生,Id就算是学生的钥匙。补贴

Answer 2

看看你的法典

$.ajax({
    url: "student_info.php",
    method: "post",
    data: {
      studentId: student_id
    },
    success: function (data, status) {
      console.log(studentId);
    },
  });

学生排出一个变量,它应当成为一种类似于变异的特性。

      console.log(data....studentId);

studentId is contained in your data object. That being said it would be good to show the full code and also log the data and status, that way the question is more reproduce-able and we ensure there are no other issues
