Javascript-将数组推入对象中的数组

Question

I have problem to push some value that assigned to be an array in the object

Here my code :

var hasil = [{  product: 'listBarang[i][0]',
                shoppers: [],
                leftOver: 'listBarang[i][2]',
                totalProfit: 0
            }]

What I think is using push method like below

hasil.shoppers.push('test')

But it give me an error like this

TypeError: Cannot read property 'push' of undefined

Is anyone know how to deal with this?

Answer 1

hasil是一个对象数组，因此，如果要处理这些对象，则需要直接访问它们，即使用hasil[0] ：

hasil[0].shoppers.push('test')
