背景：在uniapp中因原生video组件功能有限，选择引入xgplayer库来展示视频播放等功能。并且APP端无法操作dom，所以使用了renderjs。

其他的不多说，主要列举一下renderjs中需要注意的点：
1、使用：在标签后，添加<script module="xgPlayerModule" lang="renderjs"></script >，然后有关操作dom的代码都写在script 标签里面。其中module的值是自定义的，后续会用这个值来调用renderjs的方法。

2、普通 script 标签是逻辑层，带renderjs的 script 标签是视图层。

3、逻辑层向视图层传值：在 template 某元素上添加 :属性名=“vue 变量”:change:属性名=“renderjs 模块名.方法名” （其中 vue 变量 为 Vue 组件中的某个数据， renderjs 模块名 为之前定义的 module 属性的值，当 vue 变量 值改变时会触发 renderjs模块名.方法名 的方法）。例如：

<view :iosTimes="iosTimes" :change:iosTimes="xgPlayerModule.changeTimes"></view><script module="xgPlayerModule" lang="renderjs">export default {data(){return {renderIosTimes: null}},methods: {changeTimes() { // 当检测到iosTimes变化时，触发此方法，重新赋值后，保存在renderjs里面的renderIosTimes 变量中，因为后面renderjs里面的其他方法要使用这个值。this.renderIosTimes = this.iosTimes}}}
</script>  

4、**视图层向逻辑层传参：**在 template 元素的事件绑定中使用 @事件=“renderjs 模块名.方法名” ，通过该方式触发 renderjs 中的方法，然后在这个方法中可以使用 this.$ownerinstance.callmethod('vue 组件中的方法名', 参数) 来调用普通 Vue 组件中的方法并传值。

this.$ownerInstance.callMethod('playerMethods')

接下来就是在renderjs中，通过xgplayer创建视频，并且完成交互

准备:
npm install xgplayer --save

以下是完整的代码案例：
video.vue中调用xgplayer组件

 <xg-player :data-idkey="modId" ref="video" :videoConfig="videoConfig" ></xg-player>import xgPlayer from '@/components/player/xgplayer';
<script>export default {data(){return {videoConfig: {videoUrl: '', // 播放地址lastPlayTime: '' // 上次播放时间}	}},methods: {changeTimes() { // 当检测到iosTimes变化时，触发此方法，重新赋值后，保存在renderjs里面的renderIosTimes 变量中，因为后面renderjs里面的其他方法要使用这个值。this.renderIosTimes = this.iosTimes}},onHide: function() { // 退出应用时调用this.$refs['video'].beforeLeave()  // 调用子组件的方法，暂停视频播放}}
</script>  

xgplayer.vue组件中：

<template><view><!-- 视频 --><view:id='videoId'class="mse-box":style="customStyle"v-if="type === 'VOD'":conEnd="conEnd" :change:conEnd="xgPlayerModule.initVideo"></view><view :iosTimes="iosTimes" :change:iosTimes="xgPlayerModule.changeTimes"></view><view :modOpenTrial="modOpenTrial" :change:modOpenTrial="xgPlayerModule.changeModOpenTrial"></view><view :playOrPauseStatus="playOrPauseStatus" :change:playOrPauseStatus="xgPlayerModule.playOrPauseVideoRenderjs"></view></view>
</template><!-- 逻辑层 -->
