用vue 写一个穿梭框

好的，以下是一个简单的Vue穿梭框组件：

<template>
  <div class="transfer-box">
    <h3>可选项</h3>
    <ul class="transfer-list">
      <li v-for="(option, index) in options" :key="index" v-show="!option.checked">
        <label>
          <input type="checkbox" v-model="option.checked" @change="onChange(index, option)">
          {{ option.label }}
        </label>
      </li>
    </ul>
    <button @click="addToSelected">添加</button>
    <button @click="removeFromSelected">移除</button>
    <h3>已选项</h3>
    <ul class="transfer-list">
      <li v-for="(option, index) in selectedOptions" :key="index" v-show="option.checked">
        <label>
          <input type="checkbox" v-model="option.checked" @change="onChange(index, option)">
          {{ option.label }}
        </label>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  name: "TransferBox",
  props: {
    options: {
      type: Array,
      required: true,
    },
  },
  data() {
    return {
      selectedOptions: [],
    };
  },
  methods: {
    addToSelected() {
      this.options.forEach((option) => {
        if (option.checked) {
          option.checked = false;
          this.selectedOptions.push(option);
        }
      });
    },
    removeFromSelected() {
      this.selectedOptions.forEach((option) => {
        if (option.checked) {
          option.checked = false;
          this.options.push(option);
        }
      });
      this.selectedOptions = this.selectedOptions.filter(
        (option) => !option.checked
      );
    },
    onChange(index, option) {
      if (this.selectedOptions.indexOf(option) !== -1) {
        this.$set(this.selectedOptions, index, option);
      } else {
        this.$set(this.options, index, option);
      }
    },
  },
};
</script>

<style>
.transfer-box {
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  margin-top: 20px;
}

.transfer-list {
  list-style-type: none;
  padding: 0;
  width: 150px;
  height: 150px;
  border: 1px solid #ccc;
  overflow-y: scroll;
  margin-right: 10px;
}

.transfer-list li {
  margin: 5px 0;
}

button {
  margin-top: 50px;
  font-size: 16px;
  padding: 5px 15px;
  border-radius: 3px;
  border: none;
  background-color: #007aff;
  color: #fff;
}

button:hover {
  cursor: pointer;
}
</style>

这里的核心逻辑是将选中的选项从可选项列表中移动到已选项列表中，以及将已选项列表中的选项移回到可选项列表中。通过checkbox的v-model绑定，可以方便地实现选中状态的同步。同时，onChange方法可以用来处理选中状态的改变，并将相应的选项从一个列表移动到另一个列表中。
