Status: RESOLVED DUPLICATE of bug 156137

(Firefox :: General, defect)

Description

[John Hansen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

Attaching an onclick event handler to an element works fine for left clicks, but
never fires off for middle- or right-clicks.

Tested in Firefox 1.5 beta 1.

Reproducible: Always

Steps to Reproduce:
1.  Attach an onclick event to any element on the page (ex:
document.getElementById("elementname").onclick = ClickFunction;)
2.  Create the ClickFunction() { alert("clicked"; );

Actual Results:  
Middle- or right-clicking the element will never fire off ClickFunction(), and
will instead perform default action.

Expected Results:  
The function should have been called.

If you check in other browsers, you'll see that the behavior is the same.
Try using 'onmouseup' instead to detect all click types.

True, I've noticed that too.  What brought up the bug report in the first place
is how to detect a middle-click.  onmouseup is not sufficient if I need to
cancel the default action of the right or middle click.

I understand that oncontextmenu works to cancel right clicks.  But there is no
(documented?) event to capture middle-clicking a link and cancel the default
action of opening a new tab.

Attaching mouseup to an anchor element and cancelling the default action on
middle-click does not prevent a new tab from being opened (and rightly so).  But
by including middle and right-clicks in the onclick event handler, it would
solve the problem cleanly.

IIRC (and I might be wrong) earlier releases of Fx 1.0 was able to catch the
middle click using the onclick handler.
