Consider a scenario where a parent component wants to display a list of items, and each item in the child list component should have an action, like "remove." The parent component defines the function to handle the removal, and the child component, when rendering each item via a scoped slot, calls this function, passing the relevant item's ID.You'll emit an event in the child component and thencall a functionin the parent component.

Here's a simplified illustration:

Child Component (`ItemList.vue`):

```vue

```

In this child component, we define a named slot called `"item"`. We then bind both `itemData` (the data for the current item) and a `removeItem` function to this slot2023年2月14日—You can think of a scopedslotas afunctionpassed into the child component.
