hi !
i did some research and looked at this link :
Mapping from Array column in DB

But i didnt get the answer i was looking for

I want my images's asset URL to look like be randomized from
fotos= [
"//kwarcens.sirv.com/ElevationBurger%2001.png" ,
//kwarcens.sirv.com/ChillAkil%2001.jpg" ,
"//kwarcens.sirv.com/500Noches%2001.jpg"
]
period.
But it doesnt work , keep getting the element[0]

this is the code i put in the js windows in the service mapping screen

var x= Math.floor((Math.random() * 2) + 1);
return value.(x)

this is my service response

and this my mapping:

and this is my JS :

looks rock solid to me..
can you help me find out what im missing?

simply put, I want to add several picture for an entry and randomize on each service call.

Hello,

Do you need to get only one random photo? If so please use JS below on that mapping:
prereturn value[Math.floor(Math.random()*value.length)];/pre

hi
it didnt work. value isin't an array to begun with .
Notice the mapping.
it's already maps fotos ( a string), not the entire array



it seems im getting a nullpointer.
i tried
return value[Math.floor(Math.random()*value.length)];
and also tried
return value[0];

neither worked

Please remove/add mapping arrows as it is shown on the screenshot below:

And add JS to the new arrow:
prevar randPhoto = value.fotos;
element.find("name=img_main").attr("src", randPhoto[Math.floor(Math.random()*randPhoto.length)];/pre

Sorry Sergiy,
It didnt work.
It says "name=img_main" doesnt exist ot isin't a valid identifier.
Seems like a standard Jquery issue,
I'm probably going to need this eventually. But for now I dropped the whole random picture idea,
