• 场景
  • 父组件通过v-model:show 显示出子组件，立马就调用子组件方法，报找不到那个方法。如下：exchangeListRef 为子组件的ref，initData为子组件方法

    let exchangePopup =  ref(false)
    const showExchangePopup = ()=> {
        exchangePopup.value = true  
        exchangeListRef.value.initData()             
    }

• 解决方法

    let exchangePopup =  ref(false)
    const showExchangePopup = ()=> {
        exchangePopup.value = true  
        nextTick(()=> {
          exchangeListRef.value.initData()
        })                
    }
