我有一個子菜單,有幾個項目。當我點擊一個列表項時,它應該添加一個類closed-menu
。jquery點擊功能不能使用列表項
我使用了點擊功能,但是當我檢查時,我無法真正看到這個類。
$(document).ready(function() {
$('li.current-menu-item').click(function() {
$(this).addClass('closed-menu-item');
});
});
出於測試目的,我用這個代碼來自動只是添加同一類和它的工作:
$("li.current-menu-item").addClass("closed-menu");
所以,我怎麼能添加的類別,只有當我點擊列表中的項目?
注:我正在開發使用WordPress undersocres啓動主題所以這裏是整個JS的網站:

對新準則可能的功能之一是預防功能正在嘗試添加。
提供複製您的問題的簡約示例。您的代碼應該按預期工作。也許別的東西(綁定在任何祖先上的其他點擊處理程序)會刪除該類,或者在DOM準備就緒後添加這些LI元素。 –
