If you just wanting to check if you are being run in compatibility mode you can use this script.
// Create new ieUserAgent object
var ieUserAgent = {
init: function () {
// Get the user agent string
var ua = navigator.userAgent;
this.compatibilityMode = false;
// alert (ua);
if(ua.indexOf("MSIE") == -1){
this.version = 0;
return 0;
}
if(ua.indexOf("compatible") == -1){
this.compatibilityMode = false;
return 0;
}else{
this.compatibilityMode = true;
return 0;
}
}
};
// Initialize the ieUserAgent object
ieUserAgent.init();
/**
* Check if client is IE and in compatibility view
*
* @returns {boolean}
*/
function isIECompatibilityMode() {
var ua = navigator.userAgent;
if (ua.indexOf("MSIE") == -1) {
return false;
}
return (ua.indexOf("compatible") != -1);
}
Hi Jason,
Actually I am looking out for how to add site URL/domain in IE compatibility Mode through JavaScript.
Or anyway to automate the process instead of manually adding URL entry in IE Compatibility View Settings.
~Thanks!

This reports IE11 as IE6 whether compatibility view is engaged or not.
