vue 循环中怎么监听 v-model='xx'

Question

div.form-group(v-for="item in items")
input.form-control.w60.mgr2(type='text' placeholder='输入商品id' v-model="item.fur_id_poi_furnitures")

this.$watch('item.fur_id_poi_furnitures',function () {})

Answer 1

监听外层 items，然后根据 val，oldVal，判断变化的元素是哪个，再做相应处理

watch: {
  items: {
    handler: function (val, oldVal) {
      console.log('a thing changed')
    },
    deep: true
  }
}
