prevent default action: IE, mousedown

[ondras]

Hi,

I am really stuck in solving the situation described in thread's title. I basically want to assign an event to element's 'mousedown' event, but I need to stop default action associated with such event.

I try:

function func(event) {
event.returnValue = false;
...do stuff here...
}
element.attachEvent("onmousedown",func);

This works for most event types, but not for 'mousedown'. In other words, the default action is always performed.

Reason for this: I need to implement drag&drop, but when I start dragging an image, a 'forbidden' cursor appears (as a result of default mousedown action).

Any help will be greatly appreciated.

You seem to be doing an IE solution only?

Not sure if this will help but:


// If the preventDefault is valid (everything but IE)
if(document.preventDefault)
e.preventDefault();
else
// IE
e.returnValue = false;

Of course I am not doing an IE-only solution. This is the IE-specific part. I use a routine similar to the one above to distinguish between event models. However, this doesn't help me in any way in solving this issue.

You may need to stop the event bubbling. In IE set event.cancelBubble=true.

No. This does not solve my problem. (by the way, there is no single reason why stopping bubbling should cancel default action)

That is correct- canceling the event propagation prevents it from needing to be cancelled beyond the current source (target) element. I assumed you had cancelled the current default.
