子组件是tool，如果不加v-if就正常，加了v-if后可以执行子组件钩子函数，但是找不到dom节点，请问如何解决，谢谢

顺晟科技：

v-show is like setting CSS display to none. So the DOM still exists, but you can’t see it.v-if is like using javascript to set element to remove from tree that you specified.

因為你給的資訊太少了 不過如果是async的問題 可以用這種方式解掉 不一定要註冊在tool上面

tool组件没写dom元素

If you want the DOM still exists, using v-show.

thanks for reply,but in my project,i need to use “v-if”,because i have to prepare the data which used by the “tool” component in an async function,if i use v-show to render the “tool” component,it would cause complex problem
