Question

我将f：ajax标签添加到我的一个页面后，tomcat自动将jsf.js脚本插入到标题中：

<script type="text/javascript" src="<app-name>/javax.faces.resource/jsf.js.jsf?ln=javax.faces&amp;stage=Development">

它在页面加载时开始在IE中引起一些奇怪的错误。最令人惊讶的是，每次重新加载页面时，它们发生的错误和位置的数量可能会有所不同，有时甚至会显着不同我应该在Chrome中提到一切都没有任何问题吗？

它不是添加jsf.js的tomcat，它的jsf实现库（在你的情况下是myfaces）读取这个（）What can cause “jsf is not defined” error in browser console

所以正常

关于你的错误，也许你有一些非法的html结构？喜欢嵌套表格？你用的是什么版本的myfaces？它是官方rls版本？尝试更新的

另一种选择是尝试手动添加js文件（只是为了看看它是否有用），就像这样

<h:outputScript name="jsf.js" library="javax.faces" target="head"/>

myfaces + ajax + IE - 页面加载问题
