Open Bug 246720 Opened 16 years ago Updated Last year
xul oncommand attribute isn't parsed when accessed through DOM
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).
firstname.lastname@example.org 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.
