我遇到問題,我的下拉菜單無法正常工作。下拉菜單有2個元素,但沒有顯示任何選項。我相信這是Javascript的問題,但我不確定爲什麼它不起作用,因爲它是直接來自NPM和MaterializeCSS的.js和.css文件。這裏是什麼樣子目前的圖像:Angular 2 MaterializeCSS JavaScript函數未調用
下面是我的一些代碼: 的index.html

我們lcome.component.html(頁面見上圖)

<!-- Dropdown Trigger -->

This is a dropdown
</a>
<!-- Dropdown Structure -->
<ul id='options' class='dropdown-content'>

</ul>

此外,一些額外的問題,但我在MaterializeCSS .css文件所做的StickyFooter修改不能正常工作的。我有一種感覺,這是爲什麼我的.js文件無法正常工作的原因。
在此先感謝!
**仍在尋找解決方案!
「node_modules \ materialize-css \ dist \ js \ materialize.min.js」斜槓應該是其他方式,我認爲。通過實現包含路徑來檢查你的index.html文件。 – Niraj
