一：html結構(change事件傳參函式改變)

<a-upload name="file" :multiple="true" accept=".zip,.json" :before-upload="beforeUpload" :remove="projectHandleRemove" @change="value => handleChange(value, record)">
　　<div @click="storageId(record)">
　　　　<a-button :disabled="!record.value||!record.value2"
 
>
　　　　　　<a-icon type="upload" /> 上傳動效檔案
　　　　</a-button>
　　</div>
</a-upload>

二：js部分(handleChange函式接受引數改變)

// 檔案上傳(value則是新傳遞過來的引數)
handleChange(data, value) {
        let that = this
        if (value.fileName) {
          value.fileName = ''
        }
        if (data.fileList.length > 1) {
 
//限制只上傳一個檔案，再次上傳時則替換(覆蓋)以前的檔案
          data.fileList.splice(0, 1)
        }
        this.$nextTick(() => {
          const formData = new FormData()
          formData.append('app', 'suprised-file')
          formData.append('file', data.file)
          const file = data.file
          wxUploadCos({
            file,
            cosCode: 
 
'suprised-file',
            loadingTitle: '上傳中',
            originFileObj: data.file
          }).then(res => {
            if (res.data) {
              that.packageUrl = res.domain + res.path
              const params = {
                'columnId': that.columnId,
                'filePath': that.packageUrl,
                'width': value.value,
                'height': value.value2
              }
              postAction(that.url.uploading, params).then((res) => {
                that.$message.success(res.msg || '操作成功')
              }).catch((err) => {
                that.$message.warning(err.msg || '操作失敗，請稍後再試')
              })
            } else {
              that.$message.warning(String(res.msg) || '檔案上傳失敗')
            }
          }).catch(() => {
            // that[picType + 'List'][0].status = 'error'
          })
        })
}
