無法從url訪問JSON中的Object

Question

我很抱歉，如果這聽起來很愚蠢，但我剛剛開始學習javascript和json，我想在做完后從twitter API訪問JSON對象

 var myjson; $.getJSON('url of the Object', function(data) { myjson = json; }); 

然而，在打開myjson后，我找不到包含50個數組的對象， 表示myjson

我知道在這里使用$ .getJSON時存在的對象，所以現在我想知道我做錯了什么，以至於對象已經消失了。

如果有人可以指出我正確的方向，我會非常感激，因為谷歌搜索后沒有出現任何問題。

還有，我使用的twitter api，

Answer 1

在您的代碼示例中，json不存在

請注意，您的成功功能會發生什么：

function(data) {
  myjson = data;
}

異步調用（當你從api收到成功響應時），所以如果你在這個函數之外檢查了myjson的內容，那么myjson還沒有被修改。

無論你想用這個json做什么，你需要在這個函數中做到這一點（或者從這個函數調用另一個函數）：

function(data) {
  myjson = data;
  //do some stuff with myjson
}
