Question: Can I disable the default browser response for Shift-click event?
Answer: In Netscape Navigator 4 or Internet Explorer 4 or newer browsers, you can distinguish the Shift-click event from a simple click, and disable the default response for Shift-click. For example, Shift-click has been disabled on this page. If you use version 4 browser (or newer) under Windows, shift-click on any hyperlink on this page to test that! (In older browsers – or if JavaScript is disabled in the browser – the user would still get the default response.)
To disable Shift-click, insert the following
code in your page's <HEAD> section:
<script language="JavaScript">
<!--
function mouseDown(e) {
var shiftPressed=0;
var evt = e?e:window.event;
if (parseInt(navigator.appVersion)>3) {
if (document.layers && navigator.appName=="Netscape")
shiftPressed=(evt.modifiers-0>3);
else shiftPressed=evt.shiftKey;
if (shiftPressed) {
alert ('Shift-click is disabled.')
return false;
}
}
return true;
}
if (parseInt(navigator.appVersion)>3) {
document.onmousedown = mouseDown;
if (document.layers && navigator.appName=="Netscape")
document.captureEvents(Event.MOUSEDOWN);
}
//-->
<script>
