由于逻辑相对简单，直接附上代码咯！愿君多采撷~~~~

html代码:

<p class="select-buyer">
 <checklist :options="fullValues"></checklist>
 <span>id: {{selectedData}}</span>
 <p class="weui-cells weui-cells_checkbox">
 <label v-for='(item, index) in checkboxData' :key="item.id" class="weui-cell weui-check_label">
 <p class="weui-cell__hd">
 <input :value="item.id" v-model="checkBox.items[index]" @click="handleInputChange" type="checkbox" name="vux-checkbox" class="weui-check">
 <i class="weui-icon-checked vux-checklist-icon-checked"></i>
 </p>
 <p class="weui-cell__bd">
 <p>{{item.value}}价格：{{item.price}}</p>
 </p>
 </label>
 </p>
</p>
