jQuery 1.9不支持$.browser 怎么判断浏览器类型和版本

$.browser.msie = /msie/.test(navigator.userAgent.toLowerCase());

 

或者

$.browser.mozilla = /firefox/i.test(navigator.userAgent);
$.browser.webkit = /webkit/i.test(navigator.userAgent);
$.browser.opera = /opera/i.test(navigator.userAgent);

检查是否为 IE6

// Old

if ($.browser.msie && 7  $.browser.version) {}

// New

if (‘undefined‘ == typeof(document.body.style.maxHeight)) {}

if (!$.support.leadingWhitespace) {}
