Javascript object to array and delete some key? Need help on javascript syntax

Hi Ger,

While Greggs nice code will give you the result you need, this is much simpler with a viewbox instead of a list and give you a much lighter component.

If you configure your viewbox to look like a list similar to Selwyn's video "AA UX Viewbox Making A List" - Videos - Viddler and then set your list value ({Action} in the video) to {[count]} and then in the items tab of the viewbox builder set the onClick event to

 var _D=this.data[v];
{dialog.object}.setValue('JSONFORM_NAME',_D);

this will give you the object data needed to populate the Jsonform
As per attached crude but very fast example

Thanks Lance for this example.

In another place of my application it would make much more sense to use a viewbox (B) in stead of a list ( list B)
At that place always only 1 record is showed. That record is selected in an at another list (say list A)

My problem is that I cannot find a way to read the value of a viewbox when the viewbox is never clicked at.

I played with the getValue definitions and event definitions of Viewbox B no luck at all.


My use case:

I have a search-list A for selecting Relations. A has the primary key (relation-id) for list B, but not all the data for list B.

B has all the relation details, When selection in list A I perform a refresh on Viewbox B which is databound, and that works great. It gets filled very fast,

But how can I fill JSonFORM B with the editcontrols matching for Viewbox B without clicking on viewbox B.
Of course I can do an extra ajaxcallback to populate JSONFORM B, but that would be a really wast of speed and servertime...


Also I from other dependent components I would like to read the actual value of viewbox B. Also I for this I can ofcourse use a state variable or an argument.
But also that i consider less elegant that reading the key direct from a viewbox. All that is possible if I use a list B instead of a viewbox B.

So why bother? I measured the statistics
If do use the viewbox instead of the list,the published size of the component drops from 1425 to 1275kb, and load time decreases from 6 to 5,5 seconds. Enough for me seek help for this :-)

Thanks in advance.

Hi Ger,
I keep forgetting about my glaring deficiencies (I'm not artistic, and I'm painfully limited to American english).
With that said, I strongly believe ajax callbacks are evil, and except for the initial load, saving data, and potientially
accessing 3rd party resources, I avoid them, choosing instead to search the appropriate javascript array.
I do this often, and after avoiding javascript as much as possible for over a decade, I've started to choose javascript
over xbasic to perform my searches.
Getting the value of viewbox B is as simple as {dialog.object}.getValue('viewboxB'). Getting the rest of the data for the
chosen record involves a little more code, but is not too difficult.

I agree, and today proved for me once again: "when you are writing a lot of code to perform a little task, go back to design"

The solution was easy: forget list AND Viewbox.

1. Make the jsonform databound.
2. after selecting the record in the search list, I load directly the jsonform with ajaxcallback
3. and from there I fill a few controls (inclusive Relation_ID) in an controlbar for display and for grabbing them in other childcontrols, all clientside...
(and ended up 50kb less again :)

I haven't touched my JSONform project for a while, but as I remember it, you shouldn't need to do an ajax callback to populate it.
I'll take a look at what I did, then see if I can replicate it with your project.
