Here is a small javascript I hacked together to test if an user has vitalize installed, might be a smarter way to do it but I don't know... :)
Anyways the code:
Happy homepage cooking!Code:<SCRIPT LANGUAGE="Javascript">
<!--
if(navigator.plugins.length >0 && navigator.plugins["Vitalize!"]){
document.write("User has vitalize <br />" );
}
else {
var ie=new ActiveXObject("ATXVitalize.Vitalize.1");
if(ie){
document.write("User has vitalize <br />" );
}
}
// -->
</SCRIPT>
Nice work :)
Nice. To make your code HTML 4.01 (Strict & Transitional) compliant a developer would need to add type="text/javascript" to the script tag (and presumably use <br> instead of <br />).
An XHTML 1.0 (Strict & Traditional) and 1.1 compliant version would look something like:
Code:<script type="text/javascript">
//<![CDATA[
if(navigator.plugins.length >0 && navigator.plugins["Vitalize!"]){
document.write("User has vitalize <br />" );
}
else {
var ie=new ActiveXObject("ATXVitalize.Vitalize.1");
if(ie){
document.write("User has vitalize <br />" );
}
}
//]]>
</script>
Umm I don't use HTML and stuff like that, so I don't really understand this... Is there a way to make the website display certain text if they do/don't have Vitalize! ?
Replace the "User has vitalize" and "User does not have vitalize" with whatever you want.Quote:
<script type="text/javascript">
//<![CDATA[
if(navigator.plugins.length >0 && navigator.plugins["Vitalize!"]){
document.write("You have vitalize");
}
else {
var ie=new ActiveXObject("ATXVitalize.Vitalize.1");
if(ie){
document.write("You have vitalize" );
} else {
document.write("You do not have vitalize");
}
}
//]]>
</script>
Updated it a bit, fixes an problem ;)Code:<script type="text/javascript">
//<![CDATA[
if(navigator.plugins.length >0 && navigator.plugins["Vitalize!"]){
document.write("You have vitalize");
}
else if(navigator.plugins.length ==0) {
var ie=new ActiveXObject("ATXVitalize.Vitalize.1");
if(ie){
document.write("You have vitalize" );
}
}
else {
document.write("You do not have vitalize");
}
//]]>
</script>
Great, this is a very useful code. :)
This code doesn't work under IE6 & 7 but on FireFox ...

}
else if(navigator.plugins.length ==0) {
var ie=new ActiveXObject("ATXVitalize.Vitalize.1");
if(ie){
document.write("You have vitalize" );

else {
document.write("You do not have vitalize");
}

I havn't tested it with out vitalize so I am unsure, but it does work as far as i say that I do have it on ie6-8.. I will take a test run with out having vitalize installed when I get the time...
in fact, in IE6 & IE7, I have no text!
Thats odd it works for me :S and you have javascript turned on? it should at least display that you dont have it, thats the last thing is does....
Yes, it's odd, the javascript is turned on ... :(Quote:

I think it only usually does that if you are in the local zone (running the file from your PC) or have security set to 'high'. If you are running the file from My Computer you can fix this by going to Tools->Internet Options->Advanced and checking the "Allow active content to run in files on My Computer" option.
Then it should fail(as in reporting that the pc doesnt have v!) - because the javascript doesnt get to create the activex :S
It won't fail if its running from My Computer because JavaScript (which is "active content") won't run either. You'd need a <noscript> or something.Quote:

JavaScript is either not enabled or not supported.

Great! it works but ...
When Vitalize is installed:
> Firefox shows "You have vitalize"
> IE shows 1st "JavaScript is either not enabled or not supported." and I click on yellow tab, IE shows "You have vitalize"
When Vitalize is not installed:
> Firefox shows "You do not have vitalize"
> IE shows 1st "JavaScript is either not enabled or not supported." and I click on yellow tab, IE shows nothing :(
Hmm, try this:
Code:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript">
//<![CDATA[
if(navigator.plugins.length >0 && navigator.plugins["Vitalize!"]){
document.write("You have vitalize");
}
else if(navigator.plugins.length ==0) {
var ie=new ActiveXObject("ATXVitalize.Vitalize.1");
if(ie){
document.write("You have vitalize" );
}
else{
document.write("You do not have vitalize");
}
}
else {
document.write("You do not have vitalize");
}
//]]>
</script>
<noscript>
JavaScript is either not enabled or not supported.
</noscript>
</body>
</html>
still doesn't works :(
Explain the behaviour.Quote:
