1、错误描述

Uncaught TypeError: Cannot read property 'msie' of undefined    at Object._show (http://localhost:8080/cmp/js/jquery.hiAlerts-min.js:41:72)    at Object.alert (http://localhost:8080/cmp/js/jquery.hiAlerts-min.js:2:317)    at hiAlert (http://localhost:8080/cmp/js/jquery.hiAlerts-min.js:84:34)    at HTMLButtonElement.<anonymous> (http://localhost:8080/cmp/js/page/index.js:62:4)    at HTMLButtonElement.dispatch (http://localhost:8080/cmp/js/jquery-1.11.0.min.js:3:8066)    at HTMLButtonElement.r.handle (http://localhost:8080/cmp/js/jquery-1.11.0.min.js:3:4767)

2、错误原因

由于jquery 1.9以及以上版本不支持$.browser.msie和$.browser.version这两个方法，而页面引入的是jquery-1.11.0.min.js，版本比1.9更高，不支持上述两个方法，导致出现这个错误

3、解决办法

将if条件判断

if ( a.browser.msie && parseInt(a.browser.version) <= 6)) {      c = c + a(window).scrollTop()}if (a.browser.msie && parseInt(a.browser.version) <= 6)) {      b = b - 175}

修改为

if ( 'undefined' == typeof(document.body.style.maxHeight)) {      c = c + a(window).scrollTop()}if ('undefined' == typeof(document.body.style.maxHeight)) {      b = b - 175}
