vue移动端日期切换 调用接口 (前一天后一天)

network中通过点击去筛选日期对应内容

效果图

这两个方法分别用于将日期减少一天和增加一天。 在 previousDay 方法中，首先创建一个新的 Date 对象 prevDate，它的初始值为当前日期。然后使用 setDate 方法将 prevDate 的日期减少一天。接下来，更新当前日期为 prevDate，并使用 moment.js 库将格式化后的日期转换为 'YYYY-MM-DD' 格式。最后，重置一些变量并调用 loadData 方法加载数据。 在 nextDay 方法中，操作与 previousDay 类似，只是将日期增加了一天而不是减少一天。

html

<div class="date" >
  <img @click="previousDay" class="pre" src="/img/uaed/pre.png" alt="">
  <span>{{ formattedDate }}</span>
  <img @click="nextDay" class="next" src="/img/uaed/next.png" alt="">
</div>
