System.Windows.Forms.WebBrowser

在前端寫 JavaScript code 辨別。

 //alert( window.navigator.appName ); // Edge, 11 -> "Netscape"==appName
 engine = null;
 if ( window.navigator.appName == "Microsoft Internet Explorer" window.navigator.appName == "Netscape" )
 {
 // This is an IE browser. What mode is the engine in?
 if ( document.documentMode ) // IE8 or later
 {
 engine = document.documentMode;
 }
 else // IE 5-7
 {
 engine = 5; // Assume quirks mode unless proven otherwise
 if ( document.compatMode )
 {
 if ( document.compatMode == "CSS1Compat" )
 engine = 7; // standards mode
 }
 // There is no test for IE6 standards mode because that mode 
 // was replaced by IE7 standards mode; there is no emulation.
 }
 // the engine variable now contains the document compatibility mode.
 //alert( engine ); // 10, 9, 8, ...
 }
