Hi freyFyLiu,
I think this code snippet will work for you. However I am confused about the scenario where you only have to assign one value. You can give the below code a try and see if it resolves your problem.

a!localVariables(
  local!fruits: {
    {
      fruitName: "apple",
      price: ""
    },
    {
      fruitName: "banana",
      price: ""
    },
    {
      fruitName: "banana",
      price: ""
    },
    {
      fruitName: "peach",
      price: ""
    },
    {
      fruitName: "peach",
      price: ""
    }
  },
  local!fruitFlag: "banana",
  local!fruitIndex: index(wherecontains(local!fruitFlag,touniformstring(property(local!fruits,"fruitName"))),1,{}),
  a!forEach(
    items: local!fruits,
    expression: {
      fruitName: fv!item.fruitName,
      price: if(
        and(
          fv!item.fruitName=local!fruitFlag,
          fv!index=local!fruitIndex
        ),
        100,
        fv!item.price
      )
    }
  )
)

Thanks,
