方法1
在video上增加属性
<video class="VideoView" id="myVideo" :src="" @error="videoErrorCallback"
:danmu-list="danmuList" enable-play-gesture="true" :poster="" objectFit="cover" enable-danmu
controls>
方法2
//可通过 wxss 设置宽高
<view class="video">
<video object-fit="" style="height:{{height}}px; width:{{width}}px;"
src=""
bindloadedmetadata="videometa"
binderror="videoErrorCallback"
></video>
</view>
bindloadedmetadata:视频元素加载完成时触发。
对bindloadedmetadata 绑定事件 videometa
videometa:function (e) {
var that = this;
//获取系统信息
wx.getSystemInfo({
success (res) {
//视频的高
var height = e.detail.height;
//视频的宽
var width = e.detail.width;
//算出视频的比例
var proportion = height / width;
//res.windowWidth为手机屏幕的宽。
var windowWidth = res.windowWidth;
//算出当前宽度下高度的数值
that.height = proportion * windowWidth;
that. width = windowWidth
}
})
},
