//这在coustom.js文件中

//这是HTML格式

我收到这样的错误
customScript.js：1未捕获的ReferenceError：未定义$
在customScript.js：1尝试了许多方法，但无法解决此错误
最佳答案
在导入customScript脚本之前，将触发jQuery。将导入行移到customScript导入上方。
<script src="docs/assets/js/vendor/jquery.min.js"></script>
<script type="text/javascript" src="customScript.js"></script>
<link href="dist/css/bootstrap.min.css" rel="stylesheet">
