我想控制什么时候回复错误消息，当成功消息，但我总是得到错误消息：
这里是我想做的：
@H_502_4@$.ajax({ type: "POST",data: formData,url: "/Forms/GetJobData",dataType: 'json',contentType: false,processData: false,success: function (response) { alert("success!") },error: function (response) { alert("error") // I'm always get this. } });控制器：
@H_502_4@[HttpPost] public ActionResult GetJobData(Jobs jobData) { var mimeType = jobData.File.ContentType; var isFileSupported = AllowedMimeTypes(mimeType); if (!isFileSupported){ // Error Response.StatusCode = (int)HttpStatusCode.BadRequest; return Content("The attached file is not supported",MediaTypeNames.Text.Plain); } else { // Success Response.StatusCode = (int)HttpStatusCode.OK; return Content("Message sent!",MediaTypeNames.Text.Plain); } }解决方法
@H_502_4@$.ajax({
type: "POST",success: function (response) {
if (response != null && response.success) {
alert(response.responseText);
} else {
// DoSomethingElse()
alert(response.responseText);
}
},error: function (response) {
alert("error!"); //
}
});
控制器：
@H_502_4@[HttpPost] public ActionResult GetJobData(Jobs jobData) { var mimeType = jobData.File.ContentType; var isFileSupported = AllowedMimeTypes(mimeType); if (!isFileSupported){ // Send "false" return Json(new { success = false,responseText = "The attached file is not supported." },JsonRequestBehavior.AllowGet); } else { // Send "Success" return Json(new { success = true,responseText= "Your message successfuly sent!"},JsonRequestBehavior.AllowGet); } }
