在jquery中嵌套的條件不起作用

Question

我正在構建一個表單，其中有一些必需的字段，但取決於data-validate =「required」指示的形式中的先前選擇;屬性。我有這個工作正常，直到我到達嵌套條件，然後沒有任何反應。

我已經設置了每個動作來改變頁面的背景顏色，就像jQuery工作的視覺指示器一樣，​​所以我不需要每次都檢查代碼以獲取數據驗證屬性。

我的完整代碼如下 - 非工作代碼開始於評論開始嵌套條件，我試圖查看是否選擇了特定的複選框。選中時，該輸入的類將從「摺疊」變爲沒有類並出現新的一系列字段。

     // and add to the new fields 

     $('select#services_select').change(function() {

打賭這裏的問題奠定了

​​

affiliatedVal是一個值（文本），因此沒有選擇檢查hasClass着，在那裏使用affiliatedInput和代替

var affiliatedVal = $('input[name="affiliated"]:checked').val(); 

使用

var affiliatedInput = $('input[name="affiliated"]:checked'); 
var affiliatedVal = affiliatedInput.val();
