我有一个创建页面,使用JsonResult动作而不是ActionResult。在ActionResult动作中,错误会显示在与出错字段相邻的视图上。目前,JsonResult只返回一个字符串,该字符串在警报框中显示。
我能在视图上显示ModelState错误吗?
控制器:
[HttpPost]
public JsonResult Create(Tload tload)
{
if (ModelState.IsValid)
{
...save changes
return Json(new { Success = 1, TransloadID = transload.TransloadID, ex = "" });
}
else
{
string totalError = "";
foreach (var obj in ModelState.Values)
{
foreach (var error in obj.Errors)
{
if (!string.IsNullOrEmpty(error.ErrorMessage))
{
totalError = totalError + error.ErrorMessage + Environment.NewLine;
}
}
}
return Json(new { Success = 0, ex = new Exception(totalError).Message.ToString()});
}
在视图中使用jQuery/JavaScript代码
function Save() {
// Step 1: Read View Data and Create JSON Object
...do stuff here
// Set 2: Ajax Post
// Here i have used ajax post for saving/updating information
$.ajax({
url: '/Expedite/Create',
data: JSON.stringify(salesmain),
type: 'POST',
contentType: 'application/json;',
dataType: 'json',
success: function (result) {
if (result.Success == "1") {
window.location.href = "/Expedite/index";
}
else {
alert(result.ex);
}
}
});
}
