解决v-model双向绑定失效的问题

<InputNumber
      v-if="judge !== 7"
      v-model="judgeNum"
      :value="judgeNum"
      :min="0"
      @on-change="getNum"
    ></InputNumber>

getNum (num) {
      if (typeof num === 'number') {
        this.$emit('getData', this.judgelabel, this.judge, this.judgeNum, null)
      } else {
        this.$Message.info('这里有默认值哦~可以自行修改哦o(*￣▽￣*)ブ')
        this.judgeNum = 1 //改变不生效
        this.$emit('getData', this.judgelabel, this.judge, this.judgeNum, null)
      }
    },

setTimeout(() => {
    this.judgeNum = 1
}, 5000)

<InputNumber
      v-if="judge !== 7"
      v-model="judgeNum"
      :value="judgeNum"
      :min="0"
      @on-blur="getNum"
></InputNumber>
// 注意这里的on-blur没有默认带参，所以通过this.judgeNum去拿到用户输入的值

<!--父组件：-->
<cCompare :init_judge="init_judge" v-model="init_judgeNum" @getData="getJudge" />
<!--通过v-model去给子组件传值-->

// 子组件：
props: {
    value: { // 注意value不写默认的返回default，但是类型type还是要写
      type: Number
    }
},
computed: {
    judgeNum: {
      get () {
        return this.value
      },
      set (val) { // 只要该值被改变,就会触发set事件
        this.$emit('input', val) // 默认input事件
        this.$emit('getData', this.judgelabel, this.judge, this.judgeNum, null)
      }
    }
},
methods: {
	getNum () { // 这里面就不须再去抛新值了，都在set里面抛了
      if (typeof this.judgeNum === 'number') {
        // this.$emit('getData', this.judgelabel, this.judge, this.judgeNum, null)
      } else {
        this.$Message.info('这里有默认值哦~可以自行修改哦o(*￣▽￣*)ブ')
        this.judgeNum = 1
        // this.$emit('getData', this.judgelabel, this.judge, this.judgeNum, null)
      }
    }
