I’m having the following problem. I dynamically created an array to receive some information.
selections
[2]{"2","alt-2-2"}
[7]{"3","alt-7-3"}
[8]{"1","alt-8-1"}
Well, in the key I write the id in the database of this record, then it is recorded the option chosen between 1 and 3 and in the last one the id of the div that was chosen. You may notice that the id of div is composed of "alt-id_no_mysql-option-chosen". Only now let’s say only option 3 is correct, only key 7 is right, and the rest are wrong. How do I navigate in the array searching which one is correct? I know that if the keys were sequential like 0,1,2... one is already solved, as I do in this case then?
I think this is what you want: var value = myArray.find(x => x == 'alt-2-2');

@Marcelovieira this find() function returns only the one that is true. But I can have dozens of true ones inside this array

But you want to return all that has the chosen option is this ? That is if you have an "alt-7-3" and another "alt-1-3" and it is the option "3" you have to return the 2 ?

This one of yours
selectionsis an array or object ? What’s inside is object or array ? If it’s object what are the keys ? It’s like an example of yourselections?– Isac
"selections" is an array. Hence I need to record what was selected. As the change can be performed before saving I did so:
selections[id_no_db] = opcao_selecionada; selections[id_no_db] = id_da_div;– Alessandro Carvalho
Hence if there are changes it will always overwrite in the id key. Only that these id vary depending on the situation.

and what is within each position of
selections?{"2","alt-2-2"}is not a valid object. You can display aconsole.log(selections)?– Isac

I still can’t figure out exactly what’s in each position, which seems to be specific objects of a class you have.
selections[2].inputgives you"alt-2-2"? How was this builtselections? If I can put an example of how you built this, I can put the answer with a working example, otherwise it gets harder.– Isac
I just declared it. var selections = [] ; Then I already use it by casting id and Selected as I reported a little above
– Alessandro Carvalho
@Alessandrocarvalho can paste here the code piece that makes the release? let’s say
selections[1] = objetoQueEstaInserindo;What I wanted to know more precisely would be the return ofconsole.log(objetoQueEstaInserindo);– Jonas Centenaro
