创建容器
<template>
<div class="right" ref="playWndBox">
<!-- 视频数据站位 -->
<div id="playWnd" class="playWnd" :style="{height: playWndHeight + 'px',width: playWndWidth + 'px'}"></div>
</div>
</template>
插件所需参数
data() {
return {
// 视频盒子的高度
playWndHeight: '',
// 视频盒子的宽度
playWndWidth: '',
oWebControl:null,
initCount:0,
pubKey:'',
playMode: 0, // 0 预览 1回放
cameraIndexCode: '', // 监控点编号
objData:{
appkey: "25585539",
ip: "39.129.177.31",
port: 1443,
secret: "D2E6l7ndVKGxow5X7ZYU"
}
}
},
初始化方法
mounted() {
// 首次加载时的到父容器的高度
this.playWndHeight = this.$refs.playWndBox.clientHeight
// 首次加载时的到父容器的宽度
this.playWndWidth = this.$refs.playWndBox.clientWidth
// 初始化摄像头
this.$nextTick(() => {
this.initPlugin()
})
// 监听resize事件,使插件窗口尺寸跟随DIV窗口变化
window.addEventListener('resize', () => {
if (this.oWebControl != null) {
this.oWebControl.JS_Resize(
this.$refs.playWndBox.clientWidth,
this.$refs.playWndBox.clientHeight
)
}
})
},
只需要调用预览方法 previewVideo,更改 cameraIndexCode 值的就可以实现预览。还需注意 init 初始化时 appkey、ip、port、secret应改为自己的参数,不然视频无法预览
