Trying to fix a if brower='IE'...

**NineTwoZero** · 05-07-2007, 08:26 AM

Code:

var IE = 'Microsoft Internet Explorer'
var FF = 'Netscape'
var browser = '+navigator.appName+'

if (browser =='IE')
{

alert("this page does not support internet explorer. You will be redirected to another page with more information.');

window.location.replace("ieusers.html");

}

trying to fix so an alertbox pops up and then when u click the OK, u get redirected to ieusers.html.

how come my homemade scripts never work?

Try this:

Code:

<!--[if IE]>
<meta http-equiv="refresh" content="3;url=ieusers.html">
<![endif]-->

It'll redirect to the IE page in 3 seconds and requires no JavaScript.
You need to put this in the <head> section with the other <meta...> tags.

Code:

var browser = navigator.appName;

That said, the technique you're trying to employ - browser detection - is flawed and unreliable. Don't do it.

alert("this page does not support internet explorer. ...

Then that page needs to be fixed. Creating two or more separate documents for different groups of visitors just adds unnecessary work for you.

The use of a dialogue box is questionable: why should the user need to know that you want to use two different documents? Implementation details should be kept from users. At best, the user won't care, at worst, they won't understand what's happening, and will become confused thinking that something's wrong.

It doesn't render anything in IE, and probably other browsers too, because you're trying to use XML-like syntax in a HTML document. This is why I constantly say that unless authors understand XML (and XHTML) throughly, they should not attempt to use it on the Web. It only leads to trouble.

Yeah, Mike's right. This is wrong:

Code:

		<script src="super.js" type="text/javascript"/>
		<!--[if IE]>
			<meta http-equiv="refresh" content="0;url=ieusers.html">
		<![endif]-->
		<script src="menu.js" type="text/javascript"/>

It should be:

Code:

<script src="super.js" type="text/javascript"></script>
<script src="menu.js" type="text/javascript"></script>

Then you wouldn't even need the redirect.

From the point of view of proper coding, there are other problems. But that change will allow the page to render fine in IE.

You may not want to code to spec. But, at least don't use self closing tags for tags that normally have a separate closing tag.

so basiclly its coz of my doctype?

**jscheuer1** · 05-07-2007, 04:16 PM

No, it is your misuse of self closing tags for your script tags. See my previous post in this thread. The DOCTYPE isn't proper for what you are doing, no. But IE will overlook that, not the invalid (for HTML - all that IE understands) tags though.
