how could I disable the browser's back button using javascript?
------------------->
About the only way you can do this is to open a new window using window.open() (specifying that the browser history should not be copied to the new window) and then close the existing one.
=======================================
It can be done in 4+ browsers but it doesn't really disable the back button, just erases the data behind it to an extant.
replace Method
The replace method replaces the current History entry with the specified URL. After calling the replace method, you cannot navigate back to the previous URL using the browser's Back button.
Syntax: location.replace(URL)
This will replace the history with the current link every time a link is clicked

<SCRIPT>
function getTag(el,str) {
while ((el!=null) && (str.indexOf(el.tagName + ":")<0))
el = el.parentElement
return el
}
function navigateTo(sURL,target) {
if ((target == '_self') | | (target=="")) {
window.location.replace(sURL);
return false;
}
if (target == '_top') {
top.window.location.replace(sURL);
return false
}
if (target =='_parent') {
parent.window.location.replace(sURL);
return false;
}
if (target == '_blank' | | parent.frames.length < 1) {
window.open(sURL, target);
return false;
}
else {
if (parent.frames[target])
parent.frames[target].location.replace(sURL);
else
window.open(sURL, target);
return false;
}
}
function checkIEClick() {
var el = getTag(event.srcElement,"A:AREA:")
if ((el!=null) && ((el.tagName=="A") | | (el.tagName=="AREA"))) {
event.returnValue = false
navigateTo(el.href,String(el.target).toLowerCase())
}
}
function checkNSClick(ev) {
if (ev.target.href) {
navigateTo(ev.target.href,String(ev.target).toLowerCase())
return false
}
}
if ((document.all) | | (document.layers))
if (document.layers) {
document.captureEvents(Event.CLICK)
document.onclick = checkNSClick
}
else
document.onclick = checkIEClick
</SCRIPT>

A little slick redirection:code/font>
<META HTTP-EQUIV="Refresh" CONTENT="1; http://www.insideDHTML.com/home.asp">
<SCRIPT>
<!--
var version = parseInt(navigator.appVersion)
// replace is supported
if (version>=4 | | window.location.replace)
window.location.replace("newPage.htm")
else
window.location.href = "newPage.htm"
// -->
</SCRIPT>
The document, <A HREF="newPage.htm">Scott's Home</A> has moved.
[/code]
The above code was found at Site Experts. I hope it is useful.
