Help me work around IE7/javascript issue...

    This is related to my last post but on a different track - maybe this is a better approach... Please don't be angry - I am losing the plot here!

    I'm trying to adapt an old piece of javascript to allow it to work with IE7 (which it wont... yet)

    At the start of my js there is a line of code:

    var ns = (navigator.appName.indexOf("Netscape") != -1);
    which detects if netscape & makes some sort of rule (I am new at this - bear with me)

    And in my searches for a IE7 equivalent I have found:
    ie7=(this.ver.indexOf("MSIE 7")>-1 && this.dom)?1:0;

    If this is the same sort of thing, how do I adapt it to my code?

    Any suggestions?

    For detecting IE7 you can use this:

    
var ie7 = (document.all && !window.opera && window.XMLHttpRequest) ? true : false;
if (ie7==true)
{
  document.write( "Is IE7" );
}
else
{
  document.write( "Is NOT IE7" );
}
    Code (markup):
    For detecting other browsers, take a look at this: http://parentnode.org/javascript/javascript-browser-detection-revisited/

    Example for Netscape:

    
var ns4 = !BO["ie"] &&  (document.layers != null) &&  (window.confirm != null) && (document.createElement == null); 
if (ns4)
{
  document.write( "Is Netscape" );
}
else
{
  document.write( "Is NOT Netscape" );
}
