input 时间字段默认值

Posted 2021-03-23 whycai

背景：

时间字段展示默认值，开始时间为当天 0点，结束时间为当天晚上12点

 

代码：

 1 <input style="Width: 180px;float:left ;" type="date" id="start_time"
 2  name="start_time" placeholder="请选择具体时间"   data-format="YYYY-MM-DD HH:mm"/>
 3 <input style="Width: 180px;float:left ;" type="date" id="end_time"
 4  name="end_time" placeholder="请选择具体时间"  data-format="YYYY-MM-DD HH:mm"/>
 5 
 6 <script type="text/javascript">
 7     //时间默认值，默认当前时间
 8     var dataCur = new Date();
 9     var dataYMD = dataCur.getFullYear() + ‘-‘ + (dataCur.getMonth() + 1) + ‘-‘ + (dataCur.getDate())
10     var dataStart = dataYMD+‘ 00:00‘
11     var dataEnd = dataYMD+‘ 23:59‘
12     $(‘#start_time‘).val(dataStart);
13     $(‘#end_time‘).val(dataEnd);
14     </script>

 

vue中写法

 1 <template>
 2     <div>
 3         <el-row style="height:30px" type="flex">
 4             <el-col :span="12">
 5                 <el-form-item label="开始时间" required>
 6                     <el-date-picker type="date" format="yyyy-MM-dd" value-format="yyyy-MM-dd" clearable
 7                                     placeholder="选择日期" v-model="form.loadDate"
 8                                     style="width:140px;"></el-date-picker>
 9                     <el-time-picker type="fixed-time" format="HH:mm:ss" value-format="HH:mm:ss" clearable
10                                     placeholder="选择时间" v-model="form.loadTime" style="width:120px;"
11                     ></el-time-picker>
