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！
有一种代码：
<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> |
