Page_Index中调用组件ComA的某个方法
this.$invoke('ComA', 'someMethod', 'someArgs');
组件ComA中调用组件ComG的某个方法
this.$invoke('./../ComB/ComG', 'someMethod', 'someArgs');
slot 组件插槽

<view slot="content">

// list.wpy
<repeat for="{{mylist}}">

</repeat>
// index.wpy
<List :mylist.sync="mylist"></List>
// 原生的事件传参方式:
<view data-id="{{index}}" data-title="wepy" data-other="otherparams" bindtap="tapName"> Click me! </view>
Page({

console.log(event.currentTarget.dataset.id)// output: 1
console.log(event.currentTarget.dataset.title)// output: wepy
console.log(event.currentTarget.dataset.other)// output: otherparams

});
// WePY 1.1.8以后的版本,只允许传string。
<view @tap="tapName({{index}}, 'wepy', 'otherparams')"> Click me! </view>
methods: {
tapName (id, title, other, event) {
console.log(id, title, other)// output: 1, wepy, otherparams
}
}
// 原生代码:
wx.request({
url: 'xxx',
success: function (data) {
console.log(data);
}
});
// WePY使用方式, 需要开启Promise支持
wepy.request('xxxx').then((d) => console.log(d));
// async/await的使用方式, 需要开启Promise和async/await支持
async function request () {
