I'm curious as to why javascript is frowned upon so much for
solving this problem. I don't particularly like javascript that
much, but in some cases, it presents a reasonable solution to
this problem. While WebWork commands are definitely the way to
go in a lot of cases, if you do have to worry about i18n or you
have commands with multiple words in them, then I think
javascript is an appropriate choice. Something like this:
<input type="submit" value="Add Item"
onclick="javascript:doAddItem();"/>
and your javascript function would be:
function doAddItem() {
document.someForm.action="<ww:url page="<name of command>"/>";
document.someForm.submit();
}
I believe this is standard Javascript that will work across all
browsers, though I am not 100% sure about that. Has anyone had
an experience where this doesn't work?
To me, the problem of multiple submit buttons in an HTML form
is due to a problem with the view technology. If HTML submit
buttons also had a "displayValue" attribute where you could
define what is displayed on the button separate from the value
of the button as a parameter, then you wouldn't have to worry
about messing with javascript, and you could easily use WebWork
commands to solve everything. But since the problem lies in the
view, why not solve the problem in the view and not have to
jump through all sorts of hoops to solve the problem elsewhere?
