jQuery/autocomplete

[David Tio <ti...@gmail.com>]

Hi All,

I need help with tapestry jQuery/autocomplete. I want to fill up another
field based on the selection on jQuery/autocomplete textfield. What's the
best way to perform such action?

The only event available seems to be provideCompletions



Regards,

David Tio

Good points, Lance. Yes I will consider adding those features to JumpStart, and at the very least I will add a link to Observe. Thanks.

Hi Geoff, as stated on the demo, the observe mixin was inspired by zone
updater but with a few very handy differences:

1. Developers don't need to deal with request parameters. These are
converted to more user friendly event arguments.

2. You can pass multiple clientside field values. In the jump-start example
you could get rid of the @persist usage with this feature.

3. Optional context, you can use the same serverside event for multiple
observe instances or pass the loop index etc.

I realise that jumpstart has far greater kudos than stitch. Would you
consider adding these features to jumpstart?

I realise this question doesn't relate to T5.4 but, for anyone who's searching the mailing list, here's a way to handle the same thing in T5.4.

<t:textfield t:id="personName" placeholder="message:search-placeholder"
	t:mixins="autocomplete,zoneupdater" zoneUpdater.clientEvent="typeahead:selected typeahead:autocompleted blur" 
	zoneUpdater.event="changeOfPersonName" zoneUpdater.zone="prop:personReviewZoneId"/>

void onChangeOfPersonName(@RequestParameter(value = "input", allowBlank = true) String personName) {
	// find the person and return an Ajax response that updates a zone.
	...
}

Is your autocomplete a select component? If so you can set the 'zone'
attribute and handle the 'onChanged' event to update the zone.

There's also the observe mixin from tapestry-stitch (
http://t5stitch-lazan.rhcloud.com/observedemo). Note: This will require a
javascript tweak to work with jquery (currently prototype specific).
