javascript - 如何验证 uploadFile js 中的格式

Question

我有一个问题，我正在通过 uploadfile js 创建一个上传函数。如果文件不是excel文件，系统将显示错误。如何通过uploadfile js实现验证excel格式？这是我的来源

$(document).ready(function() {
    var uploadObj = $("#fileuploader").uploadFile({
        url:"php/upload.php",
        fileName:"myfile",
        uploadStr: "Nhập file upload",
        abortStr:"Hủy bỏ",
        uploadErrorStr:"Lỗi khi upload, vui lòng kiểm tra lại",
        sizeErrorStr:"Dung lượng file vượt quá giới hạn",
        autoSubmit:false
    });
});

您尝试过 allowedTypes: 'xls,xslx' 吗？

您也可以尝试 onSelect 回调:

onSelect: function(files) {

  if (files[0].type != 'application/vnd.ms-excel') {
    throw new Error('Not excel file');
  }
}
