uniapp parent component uses prop to pass asynchronous data to child components

In the parent-child component, the rendering relationship is that the mounted of the child component is rendered first, and then the mounted of the parent component is rendered, so the asynchronous data in the parent component is passed to the child component, which will cause the child component to not get the parent component asynchronouslydata situation.

So we can adopt a simple method. In the parent component, only after the asynchronous data is successfully obtained, the child component will be rendered and this problem will not occur!!!!!!!
