Obviously browser is not defined. Any idea what could be causing this. Same error in Chrome and FF.
显然浏览器没有定义。知道是什么原因造成的。Chrome 和 FF 中的错误相同。

$.browserwas removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.
$.browser从 1.9 版开始从 jQuery 中删除。它现在可以作为插件使用。通常建议避免浏览器检测，这就是它被删除的原因。
