From the jQuery docs for jQuery.browser:
来自 jQuery 文档jQuery.browser：
This property was removed in jQuery 1.9and is available only through the jQuery.migrate plugin. Please try to use feature detection instead.
此属性已在 jQuery 1.9 中删除，并且只能通过 jQuery.migrate 插件使用。请尝试改用特征检测。
So you'll have to drop down to an older version of jQuery or use the migrate plugin.
因此，您必须使用旧版本的 jQuery 或使用migrate 插件。

I also had similar problem as this property was removed in jQuery 1.9... Add below code inside your page script tag.
我也有类似的问题，因为这个属性在 jQuery 1.9 中被删除了......在你的页面脚本标签中添加下面的代码。
jQuery.browser = {};
(function () {
jQuery.browser.msie = false;
jQuery.browser.version = 0;
if (navigator.userAgent.match(/MSIE ([0-9]+)\./)) {
jQuery.browser.msie = true;
jQuery.browser.version = RegExp.;
}
})();

e=n.browser.msie&&"6.0"==n.browser.version
e=n.browser.msie&&"6.0"==n.browser.version
I guess it should be like this
我想应该是这样的
e == n.browser.msie && "6.0"==n.browser.version
or
e === n.browser.msie && "6.0"=== n.browser.versionfor strict equality
或
e === n.browser.msie && "6.0"=== n.browser.version严格平等

I had a similar problem with another older script of mine however the majority of users will be running a version of IE over 6.0 so it really was not a big deal for me to give support to 6.0 or below. What I did was just change the line that said
我的另一个旧脚本也有类似的问题，但是大多数用户将运行 6.0 以上的 IE 版本，因此支持 6.0 或以下版本对我来说真的没什么大不了的。我所做的只是改变了那句话
var isIE6 = ($.browser.msie && &.browser.version < 7);
to
到
var isIE6 = false;
