一、效果图
二、参数配置
1、代码示例
<t-antd-selectv-model="selectVlaue":optionSource="stepList"@change="selectChange"
/>
2、配置参数(Attributes)继承 a-select Attributes

v-model | 绑定值 | boolean / string / number/Array | - |
mode | 设置’multiple’'tags’多选 (显示全选) | String | - |
optionSource | 下拉数据源 | Array | - |
width | select宽度(可以设置百分比或px) | String | 100% |
customLabel | 是否自定义设置下拉label | String | - |
valueKey | 传入的 option 数组中,要作为最终选择项的键值 key | String | ‘key’ |
labelKey | 传入的 option 数组中,要作为显示项的键值名称 | String | ‘label’ |
isShowPagination | 是否显示分页(分页不显示全选框) | Boolean | false |
paginationOption | 分页配置项 | Object | - |
2-1、paginationOption配置参数(Attributes)继承 a-pagination Attributes
参数 | 说明 | 类型 | 默认值 |
---|---|---|---|
current | 当前页数 | number | 1 |
pageSize | 每页显示条目个数 | number | 6 |
total | 总条目数 | number | 0 |
bind | 继承a-pagination属性 | Object | - |
3、继承 a-select&&a-pagination events
事件名 | 说明 | 返回值 |
---|---|---|
current-change | 当前页码 | 当前选中的页码 |
