How can I programmatically disable IE compatibility mode?

问题

I have been stuck on this one for a while - I couldn't figure out why a website renders differently in two identical versions of Internet Explorer. Half an hour ago I came across a compatibility mode button in IE which made me really angry.

Disabling compatibility mode has fixed my problem.

Is there a way to disable it programmatically, i.e. from a web page?

Edit:

Just came across this blog https://blogs.msdn.com/b/askie/archive/2009/03/23/understanding-compatibility-modes-in-internet-explorer-8.aspx

I'll post an example code after reading the article

If you want the "old" rendering, and no button to show up on the toolbar so that users can switch modes you can use this:

<head>
  <!-- Mimic Internet Explorer 7 -->
  <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" >
  <title>My Web Page</title>
</head>

other options (old and new) include:IE=5, IE=7, IE=8, or IE=edge

(edge equals highest mode available)

You probably need to set your DOCTYPE correctly. Check out MSDN's articles on DOCTYPE and Defining Document Compatibility for more info.

Please also note that also IE8 browser settings can enforce a certain mode. I have a customer who has IE8 compatibility mode enforced by policy in intranet mode.

Please add to force IE not apply Compatibility Mode

<meta http-equiv=Content-Type content="text/html; charset=utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8">

In my case, I fixed it by adding the following tag after the <head> tag:

<meta content="IE=edge" http-equiv="X-UA-Compatible">
