 $('#fileUpload').on('change', function (e) {
    temp = $(this).val().split('.').pop().toLowerCase();
    path = $(this).val();

    if (jQuery.inArray(temp, ['gif', 'png', 'jpg', 'jpeg']) == -1) {
        resetFormElement(jQuery(this));
        window.alert('Not an image!');
    } else {
        files = jQuery('#fileUpload').prop("files")[0];
        blobURL = window.URL.createObjectURL(files);
        $('#Crew_preview img').attr('src', blobURL);
        $('#Crew_preview').slideDown();
        $(this).slideUp(); 
        e.preventDefault();
        e.stopPropagation();

是否在表单中指定enctype属性？“enctype=“multipart/form data”'您好，我没有使用enctype=“multipart/form data”，但现在我将尝试引用：我将研究感谢的问题

function AjaxForm(form, action) {

temp = $("form").serializeArray();
var SendData = new Object();


for (var i = 0; i < temp.length; i++) {

    name = temp[i].name;
    value = temp[i].value;
    SendData[name] = value;
}

  AddCrew(SendData);

function AddCrew(addData) {

addData["CompetencyID"] = addData["Competency"];
delete addData.Competency;
$.ajax(
      {
          url: 'Crew/AddCrew',
          type: 'POST',
          dataType: 'json',
          contentType: 'application/json; charset=utf-8',
          data: JSON.stringify({ incomingData: addData }),
          success: function (Id) {
              if (isGuidEmpty(Id)) {
                  alertify.alert("Crew was successfully added..");
                  $("#CrewGrid").jqxGrid('clear');
                  CrewGridFocus(Id); // crew.js create olan datayı gride bind eder
              }
              else {
                  alertify.error("a problem has occurred, try again later");
              }

          },

          error: function (jqXHR, textStatus, errorThrown) {
              alertify.alert("AddContract function error");
          }
