uni-app之数据状态改动后页面不刷新踩坑
<p>今天有个需求，在onshow里面执行函数，请求过来一堆代取的包裹（快递），然后勾选之后把数据集合放到一个list里面给后端发过去，这些包裹状态就变成了已取，正常情况下应该是到了下一个界面，但是uni-app的request请求并没有实时更新，这些勾选完的快递还在，只有刷新页面才会消失，我这时候的第一想法是在勾选完之后发送list的函数之后重新调用页面加载函数，但是服务器处理数据明显需要时间，要远不及js的执行顺序来的快，但是这种重新请求数据的逻辑上是可行的，所以我利用了一个延时器，在一秒之后重新请求，这个时间足够服务器响应，也就完成了一个数据虚假实时更新，希望uni-app以后能更加完善，解决掉这个问题，还有v-for在自定义组件失效，以及诸多坑。</p><p>页面加载函数</p>
