click事件在ios端的坑
在查看日志时发现有的ios微信端的event事件没有发出来，但也不是全部，比如用iphone5 sarifi测试是好的（貌似出现过一次发不出的情况）

还有一部分是只发了option请求

查看下来，安卓端没问题，ios端有问题。
网上找了一下，有说在点击事件的元素上加上css：
cursor:pointer;
还有的说触发事件的标签必须是
但我的情况，因为是用quasar，发现在
<div tabindex="0" class="q-item q-item-type row no-wrap row justify-center q-item--clickable q-link cursor-pointer q-focusable q-hoverable">

从chrome开发者工具可以看到每一层都有cursor:pointer; 说明加上也没用。事件的话也是加在最外层，但就算是click发生在内层，根据事件冒泡原理，应该在外层可以执行到才对。
我猜还是由于移动端对click事件的支持不好有关，网上有说需要button.on("click",...)代替 button.click(),但由于我用的vue框架都是用@click这样写所以没法这么改。
网上是说用vue的click事件在ios端会有延迟，我也不清楚时不是真的延迟（不过event有的Post请求报499错误，那可能真的是延迟）。
现在先用@touchstart在移动端代替@click试试，看还有没有问题
