私はAjax POSTメソッドを使用してクロスドメイン結果を取得しています。結果は、私が実行したときのために、戻ってきている：JSONオブジェクト：TypeError：element is null
var results = JSON.stringify(data);
console.log(results);
私は、次の取得：問題は、私は、この関数を実行するときである

、私は次のエラーを取得しています：
をTypeError: element is null
function getSubfolders(acctId,repoId,fldrId)
{
$.ajax({
type: 'POST',
url: 'http://52.36.x.xxx/sdws/appv1/accts/' + storage.get('LoginID') + '/repos/' + repoId + '/fldrs/' + fldrId,
crossDomain: true,
xhrFields: {
withCredentials: true
},
data: '{"CASCD":"true"}',
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(data) {
$.each(data.RSP.FLDR, function(index, element) {
console.log(element.NM);
});
},
error: function(e) {
console.log(e);
}
});
}
私はここで何が欠けているのか分かりません。それぞれのステートメントはループしているようですが、私は "null"要素を取得しています。私が戻ってきたオブジェクトに基づいて、 "Folder 1"、 "Folder 4"などが得られるはずです。
申し訳ありませんが、あなたは右、私は私のコメントを削除しています。 – Blauharley
try：if（要素！= null）console.log（要素.NM）;あなたはどこかでnullのFLDRを持っていると確信しています –
その特定のオブジェクトのあなたの値のどれも 'nm'プロパティを持っていません。私はあなたが思っていることを反復していないか、またはネストされたオブジェクトのプロパティを参照する方法をさらに誤解していると思われます。 –
