element el-date-picker 选择指定星期

这里以el-date-picker只能选择周日为例

1. 设置picker-options

<el-date-picker
         v-model="value1"
         type="date"
         placeholder="选择日期"
         :picker-options="pickerTime">
</el-date-picker>

data(){
    return{
          pickerTime: {
                  disabledDate: (time) => {
                         return time.getDay() != 0
                  }
      }
