i had refused using nodeid ("termid") and It has been worked in later nevow
version (0.9.27)!
I tried to get widget in 2 ways
1)
var node = $("termid");
var widget = Nevow.Athena.Widget.get(node);
2)
var widget = Nevow.Athena.Widget.fromAthenaID("termid");
both of a case give exception (cannot find node by id)
I've added a method keypress2 into AaccWeb.Users (aacc_web.js)
and string mystr = u"""<textarea cols="10" rows="5" onkeypress="return
Nevow.Athena.Widget.get(this).keypress2(event);">""" + sym +
u"""</textarea>""" into aacc_web.py
aacc_web.py
< mystr = u"""<textarea id="termid" cols="10" rows="5" onkeypress="return
keypress(event)">""" + sym + u"""</textarea>"""
> #mystr = u"""<textarea id="termid" cols="10" rows="5" onkeypress="return
keypress(event)">""" + sym + u"""</textarea>"""
> mystr = u"""<textarea cols="10" rows="5" onkeypress="return
Nevow.Athena.Widget.get(this).keypress2(event);">""" + sym +
u"""</textarea>"""
aacc_web.js
// import Nevow.Athena
function keypress(event)
{
var key = event.charCode ? event.charCode : event.keyCode;
//var node = $("termid");
//var widget = Nevow.Athena.Widget.get(node);
var widget = Nevow.Athena.Widget.fromAthenaID("termid");
if (widget) {
alert("widget get ok");
widget.callRemote("aacc_keypress", event.charCode, event.keyCode,
event.metaKey, event.altKey, event.ctrlKey, event.shiftKey);
}
else {
alert("widget get error");
}
}
AaccWeb.Users = Nevow.Athena.Widget.subclass("AaccWeb.Users");
AaccWeb.Users.methods(
> function keypress2(self, event)
> {
> var key = event.charCode ? event.charCode : event.keyCode;
> self.callRemote("aacc_keypress", event.charCode, event.keyCode,
event.metaKey, event.altKey, event.ctrlKey, event.shiftKey);
> },
function start(self, node, event) {
self.callRemote("aacc_start");
return false;
},
function showConference(self, toWhat) {
var client_data = Nevow.Athena.NodeByAttribute(self.node, "class",
"Users");
client_data.innerHTML = toWhat;
}
);
ps:
however, why in old versions (0.9.0) it worked without these changes and in
new (0.9.27) is not
