我有一個導航欄文檔，其下拉菜單不起作用。它適用於我的codepen，但不是通過我的文本編輯器（Sublime）。我已經搜索了一個解決方案，所以我在這裏。Bootstrap導航欄下拉菜單不能在瀏覽器中工作，Codepen好的
我曾嘗試：
-Bootstrap文檔
-Making確保jQuery腳本的自舉腳本
- 三檢查我的關閉谷歌搜索和StackOverflow上的
-Lots之前。
-Adding驗證碼：
<script>
$("document").ready(function() {
$(".dropdown").dropdown();
});
</script>
這就是我認爲是相關的代碼。任何見解我的錯誤將不勝感激。
