如何在uploadFile js中验证格式

Question

我遇到问题，我正在通过uploadfile js创建一个函数上传。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
    });
});

Answer 1

您是否尝试过allowedTypes：＆＃39; xls，xslx＆＃39; ？

你也可以尝试onSelect回调：

onSelect: function(files) {

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

Answer 2

这将对您有所帮助：

$("#fileuploader").change(function () {
     var ext = $(this).val().split('.').pop();
     if (ext != 'give extension here') {
         alert("Please valid file type");
         return false;
     }
});
