如何检测Internet Explorer 11及更低版本?

9 javascript internet-explorer

我想知道如何检测我的网站用户是否使用Internet Explorer 11或更低版本的Javascript.

它应该兼容并适用于所有这些版本.

怎么实现呢?

在这里,这应该适合你:

//Per Icycool, one liner
//function isIE(){
//                 return window.navigator.userAgent.match(/(MSIE|Trident)/);
//               }

function isIE() {
    var ua = window.navigator.userAgent; //Check the userAgent property of the window.navigator object
    var msie = ua.indexOf('MSIE '); // IE 10 or older
    var trident = ua.indexOf('Trident/'); //IE 11

    return (msie > 0 || trident > 0);
}


//function to show alert if it's IE
function ShowIEAlert(){
    if(isIE()){
       alert("User is using IE");
    }
}

  • `window.navigator.userAgent.match(/(MSIE | Trident)/)`如果你想在1行中完成它 (8认同)

我想简化正确的答案。这将返回true或false:

function is_IE() {
  return (window.navigator.userAgent.match(/MSIE|Trident/) !== null);
}

检查documentmode - IE 唯一的属性:

if (document.documentMode) 
    alert('this is IE');
