JS代码判断IE不同版本

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"); window.location.href="http://xxxx.com";} 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>
