使用checkValidity（）验证只需在从控制器

Question

我正在使用formData提交表单，因为我的from中有一些文件。有一次，当我提交表单时，只需在成功提交表单后跳过成功。它发生一次，我试图使用Html 5 ajax验证，但当我试图使用自定义验证其工作正常。

function propertyDetails() {
    $('#submitPropertyDetails').click(function () {
        if (window.FormData !== undefined) {
            if (isValidPropertyDetails() && getPropertyFormData() != null) {
                showLoading();
                $.ajax({
                    url: '/Member/PropertyDetails',
                    type: "POST",
                    contentType: false,
                    processData: false,
                    data: getPropertyFormData(),
                    success: function (result) {
                        setAmentiesDetails(result);
                        hideLoading($('#propertyDetails')[0]);
                    },
                    error: function (jqXhr) {
                        alert(jqXhr.statusText);
                        $errors = jqXhr.responseJSON; 
                        hideLoading($('#propertyDetails')[0]);
                    }
                });
            }
        }
        else {
            alert("FormData is not supported.");
        }
    });
};
   function getPropertyFormData() {
        // Create FormData object 
       var form = $('#propertyDetails')[0];
        var officeTypeDetails = new FormData(form);
        return officeTypeDetails;
   };
   var isValidPropertyDetails = function () {
       if ($('#propertyDetails')[0].checkValidity()) {
           return true;
       }
       else
       return false;
   };
