Filtering an iteration

[sdanigo]

When I map an array of data on the screen, in the screen side of the mapping, can I put a javascript test saying :

'if in the left side of the mapping, someValue == someTest then skip that iteration and go to the next one' ?

Thanks

Hello Sylvain,

Should be possible. Please take a look here https://devcenter.appery.io/documenta...

I have a model with 6 members. I have a made an array of objects using this model. How do I refer to a specific Member using the custom JS on the mapping page?

Hi Sylvain,

That is an interesting question.
There are a couple of ways you can do it.

1. filter away the record(iteration) that you don't want in the server side. Use a 'query' service instead of 'list' service Or create your own server code that only return the records(iterations) you want.

2. hide the records(iterations) after mapping. Add a javascript after "success: Mapping" on your page service. in that javascript, iterate the interface control that displays your records and hide those with values you don't want.

   Hope this helps

Hi Dongzhi. Any helpful resources on how to accomplish this?

Hi Henry,
If you already have an array, you may use $.each() function from jquery to iterate each member. the following link about jquery selectors and the $.each() function should help.
