将旧版本jQuery升级到新版本的jQuery

需要将项目中的旧版本jQuery升级到新版本的jQuery，为解决兼容性问题得下载一个js兼容包。
例子：升级的项目中jQuery1.x到jquery3.x,需要一个jquery-migrate-3.1.0.js文件, 就完成了。

示例如下：

<!-- 旧的注释 -->
<!--
<script type="text/javascript" src="WebContent/jQuery/jQuery-1.4.1.js">
</scrip>
-->
<!-- 导入新的 -->
<script type="text/javascript" src="WebContent/jQueryUpgrate/jquery-3.2.1.js">
</script>
<script type="text/javascript" src="WebContent/jQueryUpgrate/jquery-migrate-3.1.0.js">
</script>

jquery.migrate-3.1.0.js　　内容如下

附上jquery-migrate的更新库：https://www.bootcdn.cn/jquery-migrate/

 ps：如果是jq1.1.12升jq1.9这种，升级时，引入jquery.migrate-1.x.x.js即可
