[Vuejs]-Use props with forEach in vuejs

“this.datas.forEach is not a function”

This mean that datas is not an Array instance because forEach is method from array prototype.

Right now, this.datas does not exist. You never give this the state with the key datas.
It looks like you’re trying to go through this.test, which is an array of objects. Is that right?

If that’s the goal, you can do so:

data() {
            return {
                postForm: this.$vform({}),
                test: [{"name":"Couleur yeux","id":3,"answer":null},{"name":"Hanches","id":6,"answer":"'Test'"}],
            }
        },

    methods: {
        createForm() {
            let arrayOfAnswers = []
            this.test.forEach((data) => {
                if (data.answer) {
                    arrayOfAnswes.push(data.answer)
                }
            })
            this.arrayOfanswers = arrayOfAnswers
        }
    },
