Triggering a form submission via JavaScript in 5.4-alpha2
Has anyone figured out how to trigger a form submission using
JavaScript in Tapestry 5.4?
In 5.3 I was able to do this:
this.form.fire(Tapestry.FORM_PROCESS_SUBMIT_EVENT)
but that does nothing under 5.4.

Cool, thanks!
I'm starting to build up some content for 5.4 documentation updates,
and all this goes in there.

Yeah, sometimes quick fixes, well, aren't!
But cool. As you're using Zones I'll mention another trick...
If you put the event handler on the document, or some parent element
that doesn't get updated, then you don't have to re-apply the event
handler on every zone / ajax update.
e.g. the following will submit the form on all select change events
and you only ever need to call jsSupport.require() once when the page
loads:
define ["t5/core/dom"], (t5) ->
return ->
t5.onDocument "change", "select", (e) ->
form = this.findParent("form")
form.trigger "submit"

Steve,
Yeah, I hadn't gotten around to switching this code to unobtrusive
JavaScript yet and was hoping for a quick substitute.
Your code did the trick, it works perfectly.
Of course, I'll still need to adjust the module to set up a additional
event handlers for other events, but I guess I can figure that out
(i.e. Initialize#invoke(String)) now that you've given me a good
start.
Thanks!

Oh, I see - you have inline javascript in the onchange handler. I
don't think that's going to work - you need to wrap the element in T5s
core DOM which is defined by RequireJS:
http://people.apache.org/~hlship/t5api/coffeescript/t5-core-dom-prototype.html
Do this instead:
/META-INF/modules/formSubmitter.js
define(["t5/core/dom"], function(t5) {
return function(selectClientId) {
return t5(selectClientId).on('change', function(e) {
var form = this.findParent("form");
return form.trigger("submit");
});
};
});
Or use CoffeeScript:
/META-INF/modules/formSubmitter.coffee
define ["t5/core/dom"], (t5) ->
return (selectClientId) ->
t5(selectClientId).on 'change', (e) ->
form = this.findParent("form")
form.trigger "submit"
Then in a render phase method in your component / page:
jsSupport.require("formSubmitter").with(select.getClientId());
Steve.

In 5.3, you had to do setSubmittingElement(). Not sure if this applies still in 5.4, but if it does,
it will need to be called.

You need to fire the "click" event on the submit button, not "submit".

Still no progress on this.
I forgot to mention that this is with a zone.
@Lance: I rendered a submit button (not hidden, for now):
<t:form ... zone="listZone">
<t:submit t:id="categorySubmit" id="categorySubmit" value="Go"/>
</t:form>
and then
<t:select .... onchange="console.log("onchange executing.");
document.getElementById('categorySubmit').fire('submit')" />
The JavaScript console shows the 'onchange executing." output but
nothing else happens (and no errors).
@Steve
Tried this.form.fire("submit"), with no change. Still nothing happens.

Try this:
this.form.fire("submit")
I've not tried it, but I was looking at:

You could render a hidden submit button and fire the click() event on it
