Vue在父组件中重新渲染子组件
匿名 · 更新于 2020/5/10
在父组件中添加如下代码
<template> <Child v-if="hackReset" /> </template> <script> export default{ data(){ return { hackSet:false, } } methods:{ //需要重新渲染时调用onClick onClick() { this.hackReset = false; this.$nextTick(() => { this.hackReset = true }) } } } </script>
$nextTick 是在下次 DOM 更新循环结束之后执行延迟回调,在修改数据之后使用 $nextTick,则可以在回调中获取更新后的 DOM
$nextTick()
Defer the callback to be executed after the next DOM update cycle. Use it immediately after you’ve changed some data to wait for the DOM update.
