vue 获取视频时长的实例代码

直接通过element-ui自带的上传组件结合js即可,代码如下:

HTML:     

<el-upload class="upload-demo" :action="actionUrl" :show-file-list="false" :on-success="handleAvatarSuccess"

:before-upload="beforeAvatarUpload">

<button class="ce-button not-hover primary">

<i class="ce-icon_upload"></i>

<span>重新上传</span>

</button>

</el-upload>

js:

beforeAvatarUpload(file) {

var fileName = file.name || ''

var ext = fileName.split('.')[fileName.split('.').length - 1]

if (ext !== "doc" && ext !== "docx" && ext !== "xls" && ext !== "xlsx"

&& ext !== "ppt" && ext !== "pptx" && ext !== "pdf" && ext !== "mp4") {

this.$notify({

title: "失败",

message: "上传资源只能是 doc/docx/xls/xlsx/ppt/pptx/pdf/mp4 格式!",

type: "error",

duration: 3000

});

return false

}

// ppt(10MB),word(10MB),excel(5MB)

if (ext == "doc" || ext == "docx" || ext == "ppt" || ext == "pptx") {

debugger

if (parseInt(file.size) > parseInt('10485760‬')) {

this.$notify({

title: "失败",

message: "上传word、ppt文件上限为10MB!",

type: "error",

duration: 3000

});

return false

}

}

if (ext == 'mp4') { // 获取视频时长

var url = URL.createObjectURL(file);

var audioElement = new Audio(url);

var duration;

audioElement.addEventListener("loadedmetadata", function (_event) {

duration = audioElement.duration; //时长为秒,小数,182.36

this.$parent.$data.wDuration = parseInt(duration)

console.log(duration);

});

}

this.$parent.$data.wFileName = file.name

this.$parent.$data.wSize = parseFloat(file.size / 1024).toFixed(2) //获取文件大小

}
