    return {
      array: [
        {
          id: 1,
          name: 云朵,

js部分

var mapper = {}
this.array.forEach(function (item, index, array) {
  mapper[item.id] = index
})
// console.log(mapper)
let that = this
this.parray.forEach(function (item, index, array) {
  let value = mapper[item.id]
  // console.log(value)
  if (value !== undefined) {
    that.array[value].statevoid = true
  }
})
console.log(this.array)
