20240625老的web应用jquery中支持新版本jquery

Posted on Edited on

老的项目中使用了1.6.x的jquery，需要升级其中的弹窗为layui，但是layui需要至少1.10.x，修改方式如下，将原来单行的jquery引用，改为保护多版本jquery，添加layui引用，最后恢复原来的jquery版本号，确保不影响原来其它jquery使用的地方。

<script src="../js/jquery-1.3.2.min.js" type="text/javascript"></script>

 <script type="text/javascript" src="../js/lib/jquery.js"></script>
<script type="text/javascript" src="../js/jquerynew.js"></script>
<script type="text/javascript" src="../js/layer/js/layer.js"></script>
<script  type="text/javascript" >var $jq = jQuery.noConflict(true);console.log($().jquery);</script>

顺便做一个批量替换的脚本
