在我的控制台中，出现以下错误：

admin-bar.min.js:formatted:84 Uncaught TypeError: e.on is not a function
at HTMLDocument.<anonymous> (admin-bar.min.js:formatted:84)
at Object.resolveWith (jquery.min.js:16)
at Function.ready (jquery.min.js:16)
at HTMLDocument.B (jquery.min.js:16)
(anonymous) @   admin-bar.min.js:formatted:84
resolveWith @   jquery.min.js:16
ready   @   jquery.min.js:16
   B    @   jquery.min.js:16<blockquote>

在admin-bar.min.js中，违规行是

 e.removeclass("nojq").removeclass("nojs"),"ontouchstart"in window ? (e.on("touchstart",function() {

更新：

healthcheck插件显示一切运行顺利。这是Wordpress中导致问题的页面的代码：

如果您使用此代码在wordpress中创建新页面，您应该能够重现该问题。

解决的问题：

wordpress已经加载了jquery，再次加载会产生问题。
