jQuery 1.9版本以上的浏览器判断方法代码分享

 var matched, browser;
jQuery.uaMatch = function( ua ) {
 ua = ua.toLowerCase();
 var match = /(chrome)[ \/]([\w.]+)/.exec( ua ) ||
 /(webkit)[ \/]([\w.]+)/.exec( ua ) ||
 /(opera)(?:.*version|)[ \/]([\w.]+)/.exec( ua ) ||
 /(msie) ([\w.]+)/.exec( ua ) ||
 ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
 [];
 return {
 browser: match[ 1 ] || "",
 version: match[ 2 ] || "0"
 };
};
matched = jQuery.uaMatch( navigator.userAgent );
browser = {};
if ( matched.browser ) {
 browser[ matched.browser ] = true;
 browser.version = matched.version;
}
// Chrome is Webkit, but Webkit is also Safari.
if ( browser.chrome ) {
 browser.webkit = true;
} else if ( browser.webkit ) {
 browser.safari = true;
}
jQuery.browser = browser;
//下面是直接写的判断，上面jq的获取方法
if (matched.browser == 'mozilla') {
 $('#Online-message .liuyan').css({'padding-left': '0px','padding-right': '0px'})
}
