Uncaught ReferenceError: XXXX is not defined

<link href="~css/QYL.common.css" rel="stylesheet" type="text/css" />
<link href="~css/QYL.common.admin.css" rel="stylesheet" type="text/css" />
<script src="~js/jquery-1.11.3.min.js" type="text/javascript"></script>
<script src="~js/jquery-ui.custom.js" type="text/javascript"></script>
<script src="~js/QYL.common.js" type="text/javascript"></script>
<script src="~js/QYL.common.edit.js" type="text/javascript"></script>
<script src="~js/load-image.all.min.js" type="text/javascript"></script>
<script src="~js/imgupload.js" type="text/javascript"></script>

以上是我对js代码的引用。

其中这3个是jquery插件  

<script src="~js/jquery-1.11.3.min.js" type="text/javascript"></script>
<script src="~js/jquery-ui.custom.js" type="text/javascript"></script>
<script src="~js/load-image.all.min.js" type="text/javascript"></script>

这3个是我自己写的js

<script src="~js/QYL.common.js" type="text/javascript"></script>
<script src="~js/QYL.common.edit.js" type="text/javascript"></script>
<script src="~js/imgupload.js" type="text/javascript"></script>

 

老是报错  Uncaught ReferenceError: XXXX is not defined

找了N遍之后发现。插件要放在自定义js之前。不然可能就会出现以上错误，但不是必然的。

正确的写法应该是

<link href="~css/QYL.common.css" rel="stylesheet" type="text/css" />
<link href="~css/QYL.common.admin.css" rel="stylesheet" type="text/css" />
<script src="~js/jquery-1.11.3.min.js" type="text/javascript"></script>
<script src="~js/jquery-ui.custom.js" type="text/javascript"></script>
<script src="~js/load-image.all.min.js" type="text/javascript"></script>
<script src="~js/QYL.common.js" type="text/javascript"></script>
<script src="~js/QYL.common.edit.js" type="text/javascript"></script>
<script src="~js/imgupload.js" type="text/javascript"></script>
