How do I capture the back button of the browser and disable it?

How can I use eventhandler with a parameter?

There is no way to do this, but what you may be able to do is to open a 
new window with the back button inactive or perhaps without a toolbar 
at all. 
There is another possibility, use the replace function : 
<SCRIPT LANGUAGE="JavaScript"><!--
 if (document.images)
     location.replace("http://www.faqts.com");
 else
     location.href = "differentpage.htm";
 //--></SCRIPT>
The followup question from Meng Xianhui reads : 
          "How can I use eventhandler with a parameter?"
I am not sure why you would want to do that here. The orginal question 
was about disbling the back button which is not possible, so all you can 
do is to replace the last history item with a new one. In the code 
above this happens automatically when the page is laoded. However, this 
code below may be handy for another purpose, but I am not sure what.   
<SCRIPT LANGUAGE="JavaScript"><!--
var dest = new 
Array('http://www.faqts.com','http://www.microsoft.com',''http://www.cis
co.com');
function newBack(i) {
 if (document.images)
     location.replace(dest[i]);
 else
     location.href = "differentpage.htm";
}
 //--></SCRIPT>
And in the body : 
<form>
<input type="button" value="FAQTS" onClick="newBack(0)">
<p>
<input type="button" value="The Dark Side" onClick="newBack(1)">
<p>
<input type="button" value="The Borg" onClick="newBack(2)">
</form>
This is untested but it should work in both IE and NN. No garantees.
