$ .getJSON無法解析數組

Question

我正在嘗試使用$ .getJSON從json（對象數組）文件中獲取數據，但是我發現此錯誤：“成功”功能無法執行。 但是，如果json內容對象正在執行，我在做什么錯呢？

我的JS和JSON代碼如下：JS：

$.getJSON('test2.json', function(data){
      console.log('getJSON callback works');
      $.each(data, function(idx, obj){
        $.each(obj, function(key, value){
          console.log(key + ": " + value);
        });
      });
    });

JSON：

[
  {
    "user_name": "Name 1",
    "user_company": "Company 1",
    "message": "Message 2",
  },
  {
    "user_name": "Name 2",
    "user_company": "Company 2",
    "message": "Message 2",
  },
  {
    "user_name": "Name 3",
    "user_company": "Company 3",
    "message": "Message 3",
  }
]

Answer 1

刪除每個對象末尾的“，”

[
  {
    "user_name": "Name 1",
    "user_company": "Company 1",
    "message": "Message 2"
  },
  {
    "user_name": "Name 2",
    "user_company": "Company 2",
    "message": "Message 2"
  },
  {
    "user_name": "Name 3",
    "user_company": "Company 3",
    "message": "Message 3"
  }
]

嘗試捕捉錯誤和成功

$.getJSON( "test.js", { name: "John", time: "2pm" } )
  .done(function( json ) {
    console.log( "JSON Data: " + json.users[ 3 ].name );
  })
  .fail(function( jqxhr, textStatus, error ) {
    var err = textStatus + ", " + error;
    console.log( "Request Failed: " + err );
})
