如何使用JavaScript检测IE / Edge？ [英] How to detect IE/Edge using javascript?

问题描述

我正尝试使用javascript将特定样式应用到基于用户使用的浏览器的页面上。我可以检测除IE / Edge以外的所有浏览器。在我的代码片段中，我只是试图检测IE / Edge并应用样式。

以下是我的代码：

  var bodyStyle = document.querySelector （ #bodyArea）; （（navigator.userAgent.indexOf（Edge）！= -1）||（!! document.documentMode == true））
 {
 alert（asdf）
 if ; 
 bodyStyle.style.paddingTop =500px; 
} 
 else 
 {
 bodyStyle.style.paddingTop =300px; 
} 
  

当我在else部分中发出警报时，它会给我一个警报，但它不适用于if部分。所以我认为我的问题在我尝试检测IE / Edge时发生。或者如果它位于其他地方，请告诉我。如果有人有任何反馈，将不胜感激。您可以使用此自定义脚本来检测IE / Edge：

  if（/ MSIE 10 / i.test（navigator.userAgent））{
 //这是Internet Explorer 10 
 window.alert（'isIE10'）; 
 
 
 if（/ MSIE 9 / i.test（navigator.userAgent）|| /rv:11.0/i.test(navigator.userAgent））{
 //这是Internet Explorer 9和11 
 window.location ='pages / core / ie.htm'; 
} 
 
 if（/Edge\/12./i.test(navigator.userAgent））{
 //这是Microsoft Edge 
 window.alert （'Microsoft Edge'）; 
}

I am trying to use javascript to apply a certain style to the pages based on which browser the user is using. I can detect all of the browsers except for IE/Edge. In my code snippet I am just trying to detect IE/Edge and apply the style.

Here is my code:

var bodyStyle = document.querySelector("#bodyArea");
if((navigator.userAgent.indexOf("Edge") != -1 ) || (!!document.documentMode == true ))
{
    alert("asdf");
    bodyStyle.style.paddingTop = "500px";
}
else
{
    bodyStyle.style.paddingTop = "300px";
}

When I put an alert in the else section it gives me an alert, but it doesn't work on the if part. So I think my problem is occurring when I try to detect IE/Edge. Or if it lay elsewhere, let me know. If anyone has any feedback, it will be greatly appreciated. Thanks in advance!

解决方案

You can use this custom script to detect IE/Edge:

if (/MSIE 10/i.test(navigator.userAgent)) {
   // this is internet explorer 10
   window.alert('isIE10');
}

if(/MSIE 9/i.test(navigator.userAgent) || /rv:11.0/i.test(navigator.userAgent)){
    // this is internet explorer 9 and 11
    window.location = 'pages/core/ie.htm';
}

if (/Edge\/12./i.test(navigator.userAgent)){
   // this is Microsoft Edge
   window.alert('Microsoft Edge');
}
