When I ran the code above, Firefox and IE all showed a popup dialog that tell me "Not IE.". Why did this happend. Is @_jscript no longer defined in IE 11?

IE version: 11.0.9600.17501

  • Yes IE is starting to support W3C standards, including dropping support for non standard browser sniffing. – Petah Jan 30 '15 at 07:08
  • Sorry. My English is not very good. So I didn't know the "conditional compilation" term and didn't search that question out. – inter18099 Jan 30 '15 at 09:43

No.

Few features in earlier versions of IE Is not Supported for IE10+ . It's Removed.

Instead of Using @_jscript You can try the following Code

 function msieversion()
{
  var ua = window.navigator.userAgent
  var msie = ua.indexOf ( "MSIE " )

  if ( msie > 0 )      // If Internet Explorer, return version number
     return parseInt (ua.substring (msie+5, ua.indexOf (".", msie )))
  else                 // If another browser, return 0
     return 0

}

  • Thank you very much. IE make web programming a little hard I think... – inter18099 Jan 30 '15 at 09:31
  • Also, this has nothing to do with HTML5 parsing. – BoltClock Jan 30 '15 at 09:32
