你可以在主页中使用动态组件来实现点击图片列表跳转到其余两页的功能，具体实现步骤如下：

1. 在主页中创建一个包含三个按钮的列表，分别对应三个组件（包括goodslist组件和另外两个组件）。
2. 使用Vue Router来实现页面跳转功能，配置路由表，并将三个组件分别对应到不同的路由路径。
3. 在主页中使用动态组件<router-view>，并通过路由跳转来实现展示不同的组件。

以下是示例代码：

<template>
  <div>
    <ul>
      <li @click="toGoodsList">跳转到GoodsList组件</li>
      <li @click="toComponent1">跳转到Component1组件</li>
      <li @click="toComponent2">跳转到Component2组件</li>
    </ul>
    <router-view></router-view>
  </div>
</template>

<script>
import GoodsList from './GoodsList.vue'
import Component1 from './Component1.vue'
import Component2 from './Component2.vue'

export default {
  components: {
    GoodsList,
    Component1,
    Component2
  },
  methods: {
    toGoodsList() {
      this.$router.push('/goodslist')
    },
    toComponent1() {
      this.$router.push('/component1')
    },
    toComponent2() {
      this.$router.push('/component2')
    }
  }
}
</script>

在路由表中，你需要定义三个路由路径，分别对应三个组件：

import GoodsList from './GoodsList.vue'
import Component1 from './Component1.vue'
import Component2 from './Component2.vue'

const routes = [
  { path: '/goodslist', component: GoodsList },
  { path: '/component1', component: Component1 },
  { path: '/component2', component: Component2 }
]

export default new VueRouter({
  routes
})

当你点击列表中的某个选项时，路由会根据对应的路径跳转到相应的组件，并在<router-view>中渲染该组件。

        {
          id: 2,

          price: 200,
          image: "https://via.placeholder.com/150",
        },
      ],

    };
  },
  methods: {
    handleClick(id) {
      if (id === 1) {
        this.currentComponent = "GoodsDetail01";
      } else if (id === 2) {
        this.currentComponent = "GoodsDetail02";
      }
    },
  },
};
