vue使用element上传视频前判断

<div v-if="detail.video == 1">
    <!--auto-upload是否选取后立即上传,limit最大允许上传个数-->
    <el-upload
       class="upload-demo"
       action="上传地址(自定义上传非必须)"
       :auto-upload="false"
       :limit="1"
       :file-list="fileListc"
       :on-change="handleChangec"
       :show-file-list="false"
    >
       <el-button size="small" type="primary">普通视频上传</el-button>
    </el-upload>
</div>

data() {
  return {
     fileListc: [], //上传的普通视频文件列表
  }
},
methods: {
    // 普通视频上传发生变化触发
    handleChangec(file, fileList) {
      let self = this;
      self.filrnei = file;
      const isVideo = file.raw.type == "video/mp4" || file.raw.type == "video/webm";

        self.$message.error("只能上传符合格式的视频!");
        self.fileListc = [];
        return;
      }
      if (!isLt25M) {
        self.$message.error("上传普通视频大小不能超过25M!");
        self.fileListc = [];
        return;
      }
      let hsk = file;
      let URL = window.URL || window.webkitURL;
      // 获取分辨率，需要先生成预览url再创建video对象
      const video = document.createElement("video");
      self.kkls = URL.createObjectURL(hsk.raw);
      video.src = self.kkls;
      video.addEventListener("canplay", function () {
