js对浏览器版本判断和内核判断

JS代码判断IE6,IE7,IE8,IE9！做网页有时候会用到JS检测IE的版本，下面是检测Microsoft Internet Explorer版本的三种代码！

第一种：

<script type="text/javascript"> var browser=navigator.appName var b_version=navigator.appVersion var version=b_version.split(";"); var trim_Version=version[1].replace(/[ ]/g,""); if(browser=="Microsoft Internet Explorer" && trim_Version=="MSIE6.0") { alert("IE 6.0"); } else if(browser=="Microsoft Internet Explorer" && trim_Version=="MSIE7.0") { alert("IE 7.0"); } else if(browser=="Microsoft Internet Explorer" && trim_Version=="MSIE8.0") { alert("IE 8.0"); } else if(browser=="Microsoft Internet Explorer" && trim_Version=="MSIE9.0") { alert("IE 9.0"); } 
</script>

第二种：

<script type="text/javascript"> if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion .split(";")[1].replace(/[ ]/g,"")=="MSIE6.0") { alert("IE 6.0"); } else if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion .split(";")[1].replace(/[ ]/g,"")=="MSIE7.0") { alert("IE 7.0"); } else if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion .split(";")[1].replace(/[ ]/g,"")=="MSIE8.0") { alert("IE 8.0"); } else if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion .split(";")[1].replace(/[ ]/g,"")=="MSIE9.0") { alert("IE 9.0"); } 
</script>

第三种：

<script type="text/javascript"> if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion.match(/7./i)=="7.") { alert("IE 7.0"); } else if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion.match(/8./i)=="8.") { alert("IE 8.0"); } else if(navigator.appName == "Microsoft Internet Explorer" && navigator.appVersion.match(/9./i)=="9.") { alert("IE 9.0"); } else if(navigator.appName == "Microsoft Internet Explorer") { alert("IE 6.0"); } 
</script>

浏览器内核判断

<script type="text/javascript">var UA = LowerCase(); if(UA.indexOf('360ee')>-1){alert("360极速浏览器");}else if(UA.indexOf('360se')>-1){alert("360安全浏览器");}else if(UA.indexOf('se')>-1){alert("搜狗浏览器");}else if(UA.indexOf('aoyou')>-1){alert("遨游浏览器");}else if(UA.indexOf('theworld')>-1){alert("世界之窗浏览器");}else if(UA.indexOf('worldchrome')>-1){alert("世界之窗极速浏览器");}else if(UA.indexOf('greenbrowser')>-1){alert("绿色浏览器");}else if(UA.indexOf('qqbrowser')>-1){alert("QQ浏览器");}else if(UA.indexOf('baidu')>-1){alert("百度浏览器");}else if(UA.indexOf('chrome')>-1){alert("谷歌浏览器");}else if(UA.indexOf('firefox')>-1){alert("火狐浏览器");}
</script>
