if condition: if the browser is IE and IE browser version is older than 9

Question

The if condition below I think it says - if the browser is IE and IE browser version is newer than 9, but I don\'t have IE 9 to test it so it is hard to know the correct out

I found cascading it works great for multibrowser detection. This code was used to change a fade to show/hide in ie 8 7 6.

$(document).ready(function(){
    if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 8.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         { if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 7.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         {if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 6.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         { $('#shop').hover(function() {
        $(".glow").stop(true).fadeTo("400ms", 1);
    }, function() {
        $(".glow").stop(true).fadeTo("400ms", 0.2);});
         }
         }
         }
       });

There's an even easier method.

Since this is a comment, it will be ignored by all other browsers except IE.

var IE;
//@cc_on IE = navigator.appVersion;

Then just use this in you'r script to detect all IE versions.

if (IE) {
//This is IE.
}
else {
//This is NOT IE.
}

Or match against any version like this:

if (IE <= 6) {}, if (IE < 9) }, if (IE == 7) {} etc etc...

Here's the source where i found these types of conditionals: http://www.javascriptkit.com/javatutors/conditionalcompile.shtml

Your code looks fine, but you forgot to set the radix parameter in parseInt:

if ($.browser.msie && parseInt($.browser.version, 10) > 9){

  // you need to wait a couple years to test if it works...
  alert("I'm IE10 or 11...");

}

This cannot cause any errors
