几年后,Edge浏览器现在使用Chromium作为其渲染引擎。
可悲的是,检查IE 11仍然是一件事情。
这是一种更直接的方法,因为应该删除IE的旧版本。
if (window.document.documentMode) {
// Do IE stuff
}
这是我的旧答案(2014年):
在Edge中,用户代理字符串已更改。
/**
* detect IEEdge
* returns version of IE/Edge or false, if browser is not a Microsoft browser
*/
function detectIEEdge() {
var ua = window.navigator.userAgent;
var msie = ua.indexOf('MSIE ');
if (msie > 0) {
// IE 10 or older => return version number
return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
}
var trident = ua.indexOf('Trident/');
if (trident > 0) {
// IE 11 => return version number
var rv = ua.indexOf('rv:');
return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
}
var edge = ua.indexOf('Edge/');
if (edge > 0) {
// Edge => return version number
return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
}
// other browser
return false;
}
用法示例:
alert('IEEdge ' + detectIEEdge());
