js：

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
}
