uniapp 日期选择器

在Uniapp中，你可以使用picker组件来实现日期选择器功能。以下是一个示例代码：

<picker mode="date" :value="date" fields="month" :start="startDate" :end="endDate" @change="bindDateChange">
  <view>{{ date }}</view>
</picker>

<script>
function getDate(type) {
  const date = new Date();
  let year = date.getFullYear();
  let month = date.getMonth() + 1;
  let day = date.getDate();
  
  if (type === 'start') {
    year = year - 10;
  } else if (type === 'end') {
    year = year + 10;
  }
  
  month = month > 9 ? month : '0' + month;
  
  return `${year}-${month}`;
}

export default {
  data() {
    return {
      date: getDate({ format: true }),
      startDate: getDate('start'),
      endDate: getDate('end'),
    };
  },
  methods: {
    bindDateChange(e) {
      this.date = e.detail.value.substr(0, 7);
      this.time = this.date;
      this.page = 1;
      this.list = [];
      this.index();
    },
  },
};
</script>

在上述代码中，你可以看到picker组件的用法。通过设置fields属性为"month"，你只能选择年月。如果想要选择年，则可以将fields属性设置为"year"。默认情况下，picker组件可以选择年月日格式。如果你希望同时显示每天，你可以将标签中的fields="month"删除，并在getDate函数中修改返回值为`${year}-${month}-${day}`。这样就可以实现日期选择器的功能了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
