Is there a way to attach a bit of javascript to OnMouseUp of a link (Can't use OnClick cos it's an ASP.NET LinkButton control) to ask the user if they're sure they want to continue?

I think that by the time the OnMouseUp event is fired, it is too late to stop the request (unless there is a command which does the equivalent of clicking the 'stop' button on the browser)

Can you write an alert function that combines with the ASP.NET onclick event?

Also, if its just one link, how about using the onmouseover event?

I thought OnClick didn't fire until OnMouseUp did? Like, OnClick is actually a combo of both OnMouseDown and OnMouseUp happening on the same element. If that's true, OnMouseUp should work...

No idea about combining it with ASP.NET... the OnClick attribute of the asp:LinkButton component needs to have the name of an ASP.NET handler in it or it will complain. There might be a way to sneak it in after it's been rendered but no idea how. Come to think of it, I could use javascript to attach the events... provided ASP.NET generates predictable IDs.

Suppose I could use the OnClick event naturally, what would the code be?

<a href="http://google.com" onclick="return confirm('Are you sure you want to continue?')">Link</a>

onclick is fired after both onmousedown and onmouseup have fired, so you could use either one I suppose. onclick is in response to a true click, (ie. button down - button up), while onmousedown is only in response to the down click, and onmouseup to the up. Thus, if a user clicks, holds, and then moves the pointer away from the object, the onclick event will not fire.

OnMouseUp is fine. Only problem is if someone clicks off the link, moves onto the link, then releases, it will ask for a confirmation and then not do anything. I'm willing to risk that.

Chroder, that's exactly what I need except... it doesn't work. The link always fires.. that is in Firefox & Opera - works fine in IE... Guess I could make it an IE Only thing..

onclick works, onmousedown or up does not.

Why not just use ASP.NET to add the onclick to your link? Something like this, perhaps:

<script language="C#" runat="server">
mylink.Attributes.Add("onclick", "return confirm('Are you sure you want to continue?')");
</script>

Didn't know you could do that. I'll try it in a bit...

OK it works, but not really - because I have the LinkButton in a DataGrid. If I move it out of the datagrid it's fine, but inside the datagrid it I get "Name 'cmdCancel' is not declared. ". Guess I'lkl have to read up on embedding controls in DataGrids... sure I've done something like this before so shouldn't be too hard...
