监听事件

<a-select

style=" 250px"

@change="get_department_id"

placeholder="请选择部门"

:value="select_option"

>

<a-select-option value="0">所有部门</a-select-option>

<a-select-option

:value="item.value"

v-for="item in All_Department"

:key="item.value"

>{{ item.label }}</a-select-option

>

</a-select>

 

export default {

 

data() {

return {

　　env: "test",

};

 

watch: {

　　env: function (newVal, oldVal) {

　　this.select_option = "0";

},

}

上面意思是 如果 env 发生变化，那么就会执行this.select_option = "0"; 从而实现下拉组件重置
