On the Why OpenOffice.org page, in addition to the conditional I.E.6 CSS
<!--[if IE 6]> <link href="/branding/css/ie6.css" rel="stylesheet"
type="text/css" media="screen" /> <![endif]-->
there is another JS browser detection script
<script type="text/javascript" src="ie6.js"></script>
This script is supposed to insert another(?) css page for i.e. 6 compatibility
var browser=navigator.appName;
var b_version=navigator.appVersion;
var version=parseFloat(b_version);
if ((browser=="Microsoft Internet Explorer") && (version=6))
{
document.write(' <link rel="stylesheet" href="ie6.css" type="text/css" />');
alert("Your browser cannot display this site correctly - please ask your
vendor for an upgrade");
}
However, it i doesn't work.
parseFloat(navigator.appVersion) will return 4 since the first number in the
string will be 4, not 6
Also, (version=6) in the if statement will always represent true since this is
an assignment and not a comparison.
The end result is that the version variable does not indicate the version and
even if it did, the version isn't being checked anyway.
browser=="Microsoft Internet Explorer" still means that only i.e. users will
have the code run, but i.e. 7 users will as well. These users will get an alert
alert("Your browser cannot display this site correctly - please ask your vendor
for an upgrade");
telling them to upgrade even if they are on the latest version, and they will
also get the CSS inserted even if they don't need it.
Even if we should be advising i.e. 7 users to "upgrade" to a better browser,
this script should probably be fixed (maybe removed? I think the conditional
statement is probably enough).
Something like:
if (navigator.appName=="Microsoft Internet Explorer") {
var versionStart = navigator.appVersion.indexOf("MSIE ");
if (versionStart != -1) {
var version=parseFloat(navigator.appVersion.substr(versionStart+5,3);
if (version==6) {
document.write(' <link rel="stylesheet" href="ie6.css"
type="text/css" />');
alert("Your browser cannot display this site correctly - please ask
your vendor for an upgrade");
}
}
}
