条件注释()<!--[if !IE]> -->
已在 Internet Explorer 10 中删除,因此仅适用于 IE9 之前的版本。
要使用 JavaScript 检测所有 IE 版本,我建议您可以检查userAgent字符串。在IE 9版本下,您可以使用条件注释来控制注释,对于IE 9+版本,您可以使用JavaScript来隐藏注释。
请检查以下示例:
<!--[if !IE]> -->
<p id="iecontent">Some IE content here</p>
<!-- <![endif]-->
<script>
//userAgent in IE7 WinXP returns: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)
//userAgent in IE11 Win7 returns: Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko
if (navigator.userAgent.indexOf('MSIE') != -1)
var detectIEregexp = /MSIE (\d+\.\d+);/ //test for MSIE x.x
else // if no "MSIE" string in userAgent
var detectIEregexp = /Trident.*rv[ :]*(\d+\.\d+)/ //test for rv:x.x or rv x.x where Trident string exists
if (detectIEregexp.test(navigator.userAgent)) { //if some form of IE
var ieversion = new Number(RegExp.$1) // capture x.x portion and store as a number
//define a flag to check whether IE version is IE 9+
var flag = false;
if (ieversion >= 12)
{
document.write("You're using IE12 or above");
flag = true;
}
else if (ieversion >= 11)
{
document.write("You're using IE11 or above")
flag = true;
}
else if (ieversion >= 10)
{
document.write("You're using IE10 or above")
flag = true;
}
else if (ieversion >= 9)
document.write("You're using IE9 or above")
else if (ieversion >= 8)
document.write("You're using IE8 or above")
else if (ieversion >= 7)
document.write("You're using IE7.x")
else if (ieversion >= 6)
document.write("You're using IE6.x")
else if (ieversion >= 5)
document.write("You're using IE5.x")
if (flag)
document.getElementById("iecontent").style.display = "none";
}
else {
document.write("n/a")
}
</script>
