computing list fields

[John5269257]

Good morning
I'm populating a list with a service, I need to do some calculations based on data returned in each record.

Example:

For each record returned by the service I have:
label1 mapped to responseParameter1
label2 mapped to responseParameter2

so my results go:
record 1:
label1: "foo"
label2: "bar"

record 2:
label1: "big"
label2: "small"

This works.
I need for each record to have label3, which is the result of a calculation involving labels 1 and 2. For example, with simple concatenation:

record 1:
label1: "foo"
label2: "bar"
label3: "foobar" < computed

record 2:
label1: "big"
label2: "small"
label3: "bigsmall" < computed

Is there a way of doing this that takes advantage of appery's inbuilt looping?
(Mapping both parameters to a single label seems allowed by the UI, but I dont know how to access the values in javascript).

Thanks for your help,
John

Map to Label both values and JS for Label:
codereturn element&#46;text() + value;/code

Thanks Marina

I'm working with a pre-defined service - in the ContentList I need to compare Title and Filename, and if they are the same, remove the filename extension and display it. If they aren't the same, display the title.

I can do the manipulation, I just don't see how i can reference each field.

My mapping below : - I've mapped "Title" and Filename to "test"

Thanks again, John

Sorry for duplicated entries - a problem with single quotes mangled my first post, which I tried to delete. On that thread (https://getsatisfaction.com/apperyio/...) you requested a screenshot of my mapping, which is above.

Thanks Marina -
I actually need to do more than concatenate - is it documented anywhere how to manipulate multiple mappings to one label? - your example works, but I need to compare two values and act accordingly, and I can't figure out how to identify each value

Hi John,

You would need to use Success or Complete event.

Success receives full data in the first parameter.

In the first parameter Complete receives jqXHR (http://api.jquery.com/Types#jqXHR) where you can also find server response.

You would need to do all the calculations there.

The system doesn't provide this. That is, you can try to map multiple values ​​to the same item, but the choice of value is not a predictable behavior. In particular, you do not know with what value JS-code for this element in mapping will be called.

[John5269257]

Katya - could I impose upon you to provide a simple example of how to receive and parse the jqXHR using javascript in appery?

I think others might find it useful too

Hi John,

REST Service has 3 events: Success, Complete, Error.
Appery.io executes AJAX requests via jQuery.ajax(); (http://api.jquery.com/jQuery.ajax/).

As in jQuery.ajax(); the following parameters are sent to event handler:
code
&#47;&#47; Error
&#47;&#47; Type: Function( jqXHR jqXHR, String textStatus, String errorThrown )
var data = arguments[0],
textStatus = arguments[1],
jqXHR = arguments[2];

&#47;&#47; Success
&#47;&#47; Type: Function( PlainObject data, String textStatus, jqXHR jqXHR )
var data = arguments[0],
textStatus = arguments[1],
jqXHR = arguments[2];

&#47;&#47; Complete
&#47;&#47; Type: Function( jqXHR jqXHR, String textStatus )
var jqXHR = arguments[0],
textStatus = arguments[1];/code

I've added your success code to the success event of a service in appery, and I'm wading through the console.logged data. A useful start, thanks
