Answer 1

js

new Vue({
        el: "#app",
        data: {
            myCheck: '',
            //用来存放每一次点击的value
            arr: []
        },
        watch: {
            myCheck: function () {
                this.arr.push(this.myCheck)
            }
        }
    })

What does this mean? ? Every time you click, the value after the click is saved
