vue+element UI中给指定日期添加标记

1.日期控件中添加:picker-options属性，即:picker-options=“myPickerOptions”

  <el-date-picker:class="item.scds !=null ?'xtsjBlue':'xtsjRed'"v-model="item.date"value-format="yyyy-MM-dd"type="date":picker-options="pickerOptions"placeholder="选择日期" @change="bsdsChange(item)"></el-date-picker>

2.在data中定义要标记的日期数组hasXtdsDate，及myPickerOptions处理逻辑，筛选出要标记的日期数组

hasXtdsDate:[],//要标记的数组
pickerOptions: {cellClassName: time => {const month = time.getMonth() + 1;const day = time.getDate();const val = time.getFullYear() + '-' + (month < 10 ? '0' + month : month) + '-' + (day < 10 ? '0' + day : day);if (this.hasXtdsDate.indexOf(val) >= 0){return 'hasXtdsDateClass';  //有系统读数的日期显示蓝色}else {return 'noXtdsDateClass'   //没有系统读数的日期显示红色}}}

3.对要进行标记的日期进行数据筛选

 this.meterList = res.bcdsres.bcds.forEach(o=>{o.taskId = row.ido.planId = row.planIdo.industrialUserId = row.industrialUserIdif(o.xtds !=null || o.xtds !=''){this.hasXtdsDate.push(o.date)}})

4.自定义日期标记的样式

<style lang="scss">.hasXtdsDateClass > div > span:after {content: "•";color: blue;bottom: -16px;position: absolute;font-size: 20px;left: 10px;}
.noXtdsDateClass > div > span:after {content: "•";color: red;bottom: -16px;position: absolute;font-size: 20px;left: 10px;
}
</style>
