组件—日期时间选择器

日期和时间点

<template>
 <div class="block">
  <span class="demonstration">默认</span>
  <el-date-picker
   v-model="value1"
   type="datetime"
   placeholder="选择日期时间">
  </el-date-picker>
 </div>
 <div class="block">
  <span class="demonstration">带快捷选项</span>
  <el-date-picker
   v-model="value2"
   type="datetime"
   placeholder="选择日期时间"
   align="right"
   :picker-options="pickerOptions">
  </el-date-picker>
 </div>
 <div class="block">
  <span class="demonstration">设置默认时间</span>
  <el-date-picker
   v-model="value3"
   type="datetime"
   placeholder="选择日期时间"
   default-time="12:00:00">
  </el-date-picker>
 </div>
</template>

<script>
 export default {
  data() {
   return {
    pickerOptions: {
     shortcuts: [{
      text: '今天',
      onClick(picker) {
       picker.$emit('pick', new Date());
      }
     }, {
      text: '昨天',
      onClick(picker) {
       const date = new Date();
       date.setTime(date.getTime() - 3600 * 1000 * 24);
       picker.$emit('pick', date);
      }
     }, {
      text: '一周前',
      onClick(picker) {
       const date = new Date();
       date.setTime(date.getTime() - 3600 * 1000 * 24 * 7);
       picker.$emit('pick', date);
      }
     }]
    },
    value1: '',
    value2: '',
    value3: ''
   };
  }
 };
</script>

日期和时间范围

<template>
 <div class="block">
  <span class="demonstration">默认</span>
  <el-date-picker
   v-model="value1"
   type="datetimerange"
   range-separator="至"
   start-placeholder="开始日期"
   end-placeholder="结束日期">
  </el-date-picker>
 </div>
 <div class="block">
  <span class="demonstration">带快捷选项</span>
  <el-date-picker
   v-model="value2"
   type="datetimerange"
   :picker-options="pickerOptions"
   range-separator="至"
   start-placeholder="开始日期"
   end-placeholder="结束日期"
   align="right">
  </el-date-picker>
 </div>
</template>

<script>
 export default {
  data() {
   return {
    pickerOptions: {
     shortcuts: [{
      text: '最近一周',
      onClick(picker) {
       const end = new Date();
       const start = new Date();
       start.setTime(start.getTime() - 3600 * 1000 * 24 * 7);
       picker.$emit('pick', [start, end]);
      }
     }, {
      text: '最近一个月',
      onClick(picker) {
       const end = new Date();
       const start = new Date();
       start.setTime(start.getTime() - 3600 * 1000 * 24 * 30);
       picker.$emit('pick', [start, end]);
      }
     }, {
      text: '最近三个月',
      onClick(picker) {
       const end = new Date();
       const start = new Date();
       start.setTime(start.getTime() - 3600 * 1000 * 24 * 90);
       picker.$emit('pick', [start, end]);
      }
     }]
    },
    value1: [new Date(2000, 10, 10, 10, 10), new Date(2000, 10, 11, 10, 10)],
    value2: ''
   };
  }
 };
</script>

默认的起始与结束时刻

<template>
 <div class="block">
  <span class="demonstration">起始日期时刻为 12:00:00</span>
  <el-date-picker
   v-model="value1"
   type="datetimerange"
   start-placeholder="开始日期"
   end-placeholder="结束日期"
   :default-time="['12:00:00']">
  </el-date-picker>
 </div>
 <div class="block">
  <span class="demonstration">起始日期时刻为 12:00:00，结束日期时刻为 08:00:00</span>
  <el-date-picker
   v-model="value2"
   type="datetimerange"
   align="right"
   start-placeholder="开始日期"
   end-placeholder="结束日期"
   :default-time="['12:00:00', '08:00:00']">
  </el-date-picker>
 </div>
</template>

<script>
 export default {

使用element UI的日期选择器时，默认显示当天日期

需求：输入框中要把当天日期显示在输入框中，并且传给后台的日期格式是2019-06-12。（如交易数据）

传给后台的时间格式为'2019-06-12'这样的格式，，这个很好实现，el-date-picker上添加value-format="yyyy-MM-dd"即可； 本来以为element UI中default-value设置之后，可以直接在输入框中显示，测试之后无用。最后通过下面的方法实现效果

<el-form-item label="交易数据">
      <el-date-picker
       type="date"
       placeholder="选择日期"
       v-model="searchFormField.date"
       style="width: 100%;"
       value-format="yyyy-MM-dd"
      ></el-date-picker>
</el-form-item>
    
   
 methods: {
  getNowTime() {
    var now = new Date();
    var year = now.getFullYear(); //得到年份
    var month = now.getMonth(); //得到月份
    var date = now.getDate(); //得到日期
    month = month + 1;
    month = month.toString().padStart(2, "0");
    date = date.toString().padStart(2, "0");
    var defaultDate = `${year}-${month}-${date}`;
    this.$set(this.searchFormField, "date", defaultDate);
  },
 }
