<!-- 基础用法:单独使用可以表示两种状态之间的切换
在el-checkbox元素中定义v-model绑定变量，单一的checkbox中，默认绑定变量的值会是Boolean，选中为true。 -->
<el-checkbox v-model="checked">备选项</el-checkbox>
<br />
<!-- 禁用状态:设置disabled属性即可。 -->
<el-checkbox v-model="checked1" disabled>备选项1</el-checkbox>
<el-checkbox v-model="checked2" disabled>备选项</el-checkbox>
<br />
<!-- 多选框组:适用于多个勾选框绑定到同一个数组的情景，通过是否勾选来表示这一组选项中选中的项
checkbox-group元素能把多个 checkbox 管理为一组，只需要在 Group 中使用v-model绑定Array类型的变量即可。
el-checkbox 的 label属性是该 checkbox 对应的值，若该标签中无内容，
则该属性也充当 checkbox 按钮后的介绍。label与数组中的元素值相对应，如果存在指定的值则为选中状态，
否则为不选中。 -->
<el-checkbox-group v-model="checkList">
<el-checkbox label="复选框 A"></el-checkbox>
<el-checkbox label="复选框 B"></el-checkbox>
<el-checkbox label="复选框 C"></el-checkbox>
<el-checkbox label="禁用" disabled></el-checkbox>
<el-checkbox label="选中且禁用" disabled></el-checkbox>
</el-checkbox-group>
<br />
<!-- indeterminate 状态:用以表示 checkbox 的不确定状态，一般用于实现全选的效果 -->
<el-checkbox :indeterminate="isIndeterminate" v-model="checkAll" @change="handleCheckAllChange">全选</el-checkbox>
<div style="margin: 15px 0;"></div>
<el-checkbox-group v-model="checkedCities" @change="handleCheckedCitiesChange">
<el-checkbox v-for="city in cities" :label="city" :key="city">{{city}}</el-checkbox>
</el-checkbox-group>
<br />
<!-- 可选项目数量的限制:使用 min 和 max 属性能够限制可以被勾选的项目的数量 -->
<el-checkbox-group
v-model="checkedCities"
:min="1"
:max="2">
<el-checkbox v-for="city in cities" :label="city" :key="city">{{city}}</el-checkbox>
</el-checkbox-group>

<!-- 按钮样式:只需要把el-checkbox元素替换为el-checkbox-button元素即可。此外，Element 还提供了size属性 -->
