我的sideNav没有在使用materializeCSS的页面上工作 这是我的HTML：
```的HTML

它表示sideNav函数没有在该页面上定义。适用于其他人，页面之间的粘贴部分没有区别。
这是追溯：
jQuery.Deferred exception: undefined is not a function (evaluating '$('.button-collapse').sideNav()') (2)
(anonymous function) — init.js:3
j — jquery.min.js:2:58607
(anonymous function) — jquery.min.js:2:88441
undefined
我用$（＆＃39; .button-collapse＆＃39;）来调用它.sideNav（）;
答案 0 :(得分：3)
我通过添加$（＆＃39; .button-collapse＆＃39;）解决了这个问题.sideNav（）;到materialize.js文件的底部。
