About Ajax Send Request

Question

hello,

 

I am getting an Internal server error after button click

 

Following is my button click code :

$('#btnUpdatePermissionContacts').click(function () {
var abc = '';
$('input[type=checkbox]').each(function () {
if (this.checked) {
abc = abc + $(this).val() + ","
//assign set value to hidden field
$('#PermissionIds').val(abc);
}
});
var formdata = new FormData();
formdata.append("PermissionIds", jQuery("#PermissionIds").val());
alert($("#PermissionIds").val());
$("#LoaderOnDEP").show();
$.ajax({
url: '/Document/UpdatePermission',
//url: '@Url.Action("UpdatePermission", "Document")',
type: "POST",
contentType: false, // Not to set any content header
processData: false, // Not to process data
data: formdata,
dataType: 'json',
success: function (result)
{
if (result.val.IsSuccess === true) {
$DocumentListPartial.html(result.partialView);
window.IsNew = true;
$("#toastupdatetdmsg").html('Permission for contact(s) updated successfully.');
toastbox('toast-updatetd');
}
else {
}
$("#LoaderOnDEP").hide();
},
error: function (err) {
alert(err.statusText);
}
});
});
