vue默认插槽的理解与实例代码

<template>
  <div class="category">
    <h3>{{ title }}分类</h3>

    <!-- 定义一个默认插槽，那么App.vue中相应的组件标签里标签体的内容会往这个插槽中放置 -->
    <slot></slot>
  </div>
</template>

<script>
export default {
  name: "Category",
  props: ["title"],
};
</script>

<style>
.category {
  background-color: skyblue;
  width: 200px;
  height: 300px;
}
h3 {
  text-align: center;
  background-color: orange;
}
</style>

<template>
  <div class="container">
    <Category title="美食">
      <img
        src="https://zqcdn.itzjj.cn/static/skin/mfw0321/static/picture/dj_scv.jpg"
        alt="1"
      />
    </Category>
    <Category title="游戏" :listData="games">
      <ul>
        <!-- 这时候因为变量直接在app.vue中所以可以直接去遍历game
        遍历完了再利用插槽的功能传递给Category.vue -->
        <li v-for="(g, index) in games" :key="index">
          {{ g }}
        </li>
      </ul></Category
    >
