现在大多都使用IE11了,这个代码检测IE11也提示低于IE8.因为IE11取消了MSIE信息,能否帮忙改一下。谢谢
下面的代码可以检测出IE11 。
<script type="text/javascript">
var userAgent = navigator.userAgent,
rMsie = /(msie\s|trident.*rv:)([\w.]+)/,
rFirefox = /(firefox)\/([\w.]+)/,
rOpera = /(opera).+version\/([\w.]+)/,
rChrome = /(chrome)\/([\w.]+)/,
rSafari = /version\/([\w.]+).*(safari)/;
var browser;
var version;
var ua = userAgent.toLowerCase();
function uaMatch(ua) {
var match = rMsie.exec(ua);
if (match != null) {
return { browser : "IE", version : match[2] || "0" };
}
var match = rFirefox.exec(ua);
if (match != null) {
return { browser : match[1] || "", version : match[2] || "0" };
}
var match = rOpera.exec(ua);
if (match != null) {
return { browser : match[1] || "", version : match[2] || "0" };
}
var match = rChrome.exec(ua);
if (match != null) {
return { browser : match[1] || "", version : match[2] || "0" };
}
var match = rSafari.exec(ua);
if (match != null) {
return { browser : match[2] || "", version : match[1] || "0" };
}
if (match != null) {
return { browser : "", version : "0" };
}
}
var browserMatch = uaMatch(userAgent.toLowerCase());
if (browserMatch.browser) {
browser = browserMatch.browser;
version = browserMatch.version;
}
document.write(browser+version);
</script> |
