如何解决Ajax数据未显示的问题？

Question

jQuery函数：

$.ajax({
    type: "POST",
    url: formsubmission,
    data: Getcity,
    success: function(response){
    var city = '';
    var citylist = response;
    $.each(citylist, function(key, value) {
      alert('each function');
      alert(value.ID);
   });
  }
});

JSON数据：

[  
   {  
      "ID":"1",
      "Name":"Ahmedabad",
      "State":"2",
      "Status":"Open"
   },
   {  
      "ID":"9",
      "Name":"Mumbai",
      "State":"2",
      "Status":"Open"
   }
]

我的jQuery函数未警告JSON数据，而且所有函数均无法正常工作——如何解决此错误？

Answer 1

Change type to method

$.ajax({
    method: "POST",
    url: formsubmission,
    data: Getcity,
    success: function(response){
    var city = '';
    var citylist = $.parseJSON( response );
    $.each(citylist, function(key, value) {
      alert('each function');
      alert(value.ID);
   });
  }
});
