在這裏，我做了一個多級菜單items.What我想的是，在點擊任何一個子元素的根的Elemen噸將有它的背景顏色改變（排序所選項目的風格）和子元素面板消失。我怎樣才能做到這一點？
MY TRY
$(document).ready(function() {
$("a").click(function(event) {
$(".has-sub").css("background-color","blue");
});
我上面的代碼試圖要做兩件事情，但沒有奏效。
「@ charset」需要在「@ import」之前出現。 – 2014-11-21 06:12:37
你可以附上截圖，你到底想要什麼？ – 2014-11-21 06:31:00
