246720 - xul oncommand attribute isn't parsed when accessed through DOM

Status: NEW

(Core :: DOM: Events, defect, P5)

Description

[Jesse Ruderman]

In bug 246719, I'm trying to make middle-clicking on more elements work, using
code like:
   oncommand="var url = ...; openUILink(url, event);"
   onclick="if(event.button==1) this.oncommand(event);"

If I middle-click an element with this before left-clicking it, I get
"this.oncommand is not a function" and openUILink is not called.  If I
left-click first, it works fine when I middle-click.

Workaround: use eval.  eval(this.getAttribute('oncommand'))

I don't like this workaround because using eval in chrome JS can be dangerous,
and because it's more code than this.oncommand(event).

[e-mail] had the same problem in bug 230401.  Once this is
fixed, the code from bug 230401 and bug 246719 should be changed to not use eval().

Note that we do have a .doCommand but it doesn't take an existing event.
