uniapp引入微信小程序自定义视频组件--记录

官方文档：https://zh.uniapp.dcloud.io/tutorial/miniprogram-subject.html

在 pages.json同级目录下 创建目录和文件：

wxcomponents：

    my-video-play：

　　index.js 

　　index.json

　　index.wxml

　　index.wxss

pages.json 全局引入：

 index.js:

Component({
    properties: {
        videoUrl: String,
        sectionId: String
    },
    methods: {
        clickFun(event) {
            this.triggerEvent('hideElement');
        },
        loadedmetadataFun(event) {
            this.triggerEvent('loadedmetadataStart', event.detail.duration);
        },
        timeupdateFun(event) {
            this.triggerEvent('videoTimeUpdate', event.detail);
        },
        endFun() {
            this.triggerEvent('palyNextVideo', this.sectionId);
        },
        getVideoContext() {
            return wx.createVideoContext("myVideo", this);
        },
        videoPlay() {
            wx.createVideoContext("myVideo", this).play();
        },
        videoPause() {
            wx.createVideoContext("myVideo", this).pause();
        },
        videoSeek(second) {
            wx.createVideoContext("myVideo", this).seek(second);
        }
    }
})

index.wxml:

<video style="position: absolute; width: 100vw; height: 100vh;" id="myVideo"
    direction="0" 
    src="{{videoUrl}}"
    autoplay 
    controls="{{false}}" 
    show-center-play-btn="{{false}}" 
    show-play-btn="{{false}}" 
    show-fullscreen-btn="{{false}}" 
    enable-progress-gesture="{{false}}"
    bindloadedmetadata="loadedmetadataFun"
    bindtimeupdate="timeupdateFun" 
    bindended="endFun"
    bindtap="clickFun"
>
</video>

index.json:

{
  "component": true
}

index.wxss: 空文件

 然后在uniapp vue文件中引入该组件：

<template>
<view>
...
<my-video-play style="position: absolute; width: 100vw; height: 100vh;" v-if="current === index && (item.videoUrl !== '')" ref='videoPlaySelf'
                            :videoUrl="item.videoUrl" :sectionId="item.sectionId" 
                            @hideElement="hideElement" @loadedmetadataStart="loadedmetadataStart" 
                            @videoTimeUpdate="videoTimeUpdate" @palyNextVideo="palyNextVideo">
 </my-video-play>
...

</view>

</template>
<script lang="ts">
...
</script>
<style lang="scss" scoped>
...

</style>
