&& 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
}
