Re: UKNM: Search Engine Optimisation vendors wanted

Apologies - you are using cross browser DHTML - its just a shame

netscape users cant take advantage of it.


marketeers close your eyes, fingers in ears, and hum loudly...

function BrowserCheck() {

	var b = navigator.appName

	if (b=="Netscape") this.b = "ns"

	else if (b=="Microsoft Internet Explorer") this.b = "ie"

	else this.b = b

	this.version = navigator.appVersion

	this.v = parseInt(this.version)

	this.ns = (this.b=="ns" && this.v>=4)

	this.ns4 = (this.b=="ns" && this.v==4)

	this.ns5 = (this.b=="ns" && this.v==5)

	this.ie = (this.b=="ie" && this.v>=4)

	this.ie4 = (this.version.indexOf('MSIE 4')>0)

	this.ie5 = (this.version.indexOf('MSIE 5')>0)

	this.min = (this.ns||this.ie)

}

According to the advice at netscape devcentre, code using objects with

poor/variable support should always be armoured by a check for the

existance of that object, rather that a specific browser or combination

thereof.


i.e. 


if (document.images) { } round image swap code rather than 


if (is.ie || is.ns) { }


And the same applies for the use of dynamic layers in IE and Netscape


Applying dynamic formatting/styles for a specific browser is a different

issue, and check must be made for relevant browsers rather than aspects

of the document object model which may or may not be supported...

And you can open your eyes again now ;-)
