web開發(fā)的時候有時候會用到JS檢測IE的版本,，下面是檢測Microsoft Internet Explorer版本的三種代碼！
方法一：
<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>
方法二：
<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>
方法三：
<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>
