Problem solved: Javascript must be entered into the "Add Javascript..." section of the Assign node. I knew this, but wasn't thinking about it when I was coding the flow.
I want to use this logic for a complex demographic interface I'm working on. I have success using push() and find() on a simple string arrays, but object arrays are throwing syntax errors. I'm hoping someone understands why.
Start node (initialize 4 variables)
| Type |
Name |
Expression |
| Array |
v_arrCarsList |
[{"color":"red","type":"minivan"},{"color":"blue","type":"truck"}] |
| Array |
v_arrAddNewCar |
[{"color":"yellow","type":"sport"}] |
| Array |
v_arrGetCar |
[] |
| String |
v_strGetCarType |
"" |
Assign node (add a new object, find a specific object, get value from found object)
| Type |
Name |
Expression |
| Array |
v_arrCarsList |
v_arrCarsList.push(v_arrAddNewCar); |
| Array |
v_arrGetCar |
v_arrCarsList.find(car => car.type=="minivan"); |
| String |
v_strGetCarType |
v_arrGetCar.type; |
