我需要将其转换为 javascript

Question

I need to convert this to javascript

$(function() {
    $('#side-menu').metisMenu();
});

Answer 1

metisMenu 不是函数，那么对象 $ 没有方法，这意味着 metisMenu 的相关插件不起作用

Answer 2

The code is in JavaScript itself but in order to use it you have to use it upon jQuery library using the metisMenu plugin. For your reference go to the GitHub repo of Metismenu
