i am facing problem to Passing Controller a Form Collection and a class type object to action using ajax call.
below are the my code.
[HttpPost]
public ActionResult AddDealNotes(DealNote objDealNote,FormCollection fc)
{
//code
}
To send a javascript ajax request using the jquery $.post object you need to make sure you use the dataType & contentType parameters.
<script>
function sendDealNotes(note, form)
{
var dataOutput = {"note": note,"form": form.serializeArray()};
var sendData = JSON.stringify(dataOutput );
var jqxhr = $.ajax({url:"/Controller/AddDealNotes", type:"POST", dataType:"json", contentType:"application/json",data:sendData})
.done(function() {
alert( "success" );
})
.fail(function(err) {
alert( "error" + err );
})
.always(function() {
alert( "complete" );
});
}
</script>

I have a function in jquery which creates a list of values being selected from a checkbox. Now I want to have this list in my controller action. I have converted this list to JSON but I am not able to pass it to the controller. I also tried creating a custom model corresponding to the json data.
Jquery Code
$("button").click(function () {
//alert("clicked");
var obj = {};
//var tempRadio = [];
for (var i = 1; i <= globalVar; i++) {
if ($("#" + i).prop("checked") == true) {
obj[i] = $('input[class=' + i + ']:checked').val();
}
}
$.ajax({
contentType: 'application/json; charset=utf-8',
dataType: 'json',
type: 'POST',
url: '#Url.Action("SkillAdd","User")',
data: JSON.stringify(obj),
//data: hello,
error:function ()
{
alert("Error");
},
success: function () {
alert(JSON.stringify(obj));
}
});
});
Controller Code
public ActionResult SkillAdd(List<string> Id, List<string> Name)
{
return View();
}
Controller Code with Custom Model
public ActionResult SkillAdd(List<MyModel> object)
{
return View();
}
You have an object in javascript but you need to create an array so that it can be mapped to List at post. So change your js code to be :
var obj = []; // it's array now
and then you will add items in it like in your loop:
obj.push( $('input[class=' + i + ']:checked').val());
and in your ajax call name the parameter what you have in your controller action:
data:{ Id : obj }
and now you can have a parameter in action method List<string> which would hold the data posted by ajax call.
public ActionResult SkillAdd(List<string> Id)
{
return View();
}
Hope it helps.
I have a partial view with a contact form.
My problem is that after the form is posted, the controller is redirecting to the actual URL of the partial view: ("LocalHost:/Views/ContactUs/MoreInformationRequest.cshtml")
I want to keep the same URL and to show only the ViewData["MsgSent"] message.
This is the call to the partial view:
#Html.Partial("~/Views/ContactUs/MoreInformationRequest.cshtml")
The View:
#using (Html.BeginForm( "MoreInformationRequest","ContactUs"))
{
.....
<input type="submit" value="send" /><br />
#ViewData["MsgSent"]
}
The Controller:
[HttpPost]
public ActionResult MoreInformationRequest(ContactUs contacts)
{
.....
ViewData["MsgSent"] = "Message sent!"
return View();
}
You could use a redirect to redisplay the page that loads the partial view:
return RedirectToAction("OriginalAction");
You could also return a specific view, particularly the view from the original action:
return View("OriginalView");
post to the server using jQuery and return false from the javascript function to stop the default processing (i.e. sending to the new url from the controller.
At the beginning I came out with this solution - to redirect to the same page using:
Request.Redirect("~/");
But I did not like this solution so I solved this by using client side code to send the data to the controller:
<script>
var request;
$('#formMoreInformationRequest').submit(function () {
var Name = document.getElementById('Name');
var Phone = document.getElementById('Phone');
// without this the validations in the page are not working.
if (Name.value == "") {
return false;}
else if (Phone.value == "") {
return false; }
else {
$('#overlay').show()
if (request) {
request.abort();
}
// setup some local variables
var $form = $(this);
// let's select and cache all the fields
var $inputs = $form.find("input, select, button, textarea");
// serialize the data in the form
var serializedData = $form.serialize();
// let's disable the inputs for the duration of the ajax request
$inputs.prop("disabled", true);
// fire off the request to /form.php
request = $.ajax({
url: "/ContactUs/MoreInformationRequest",
type: "post",
data: serializedData
});
// callback handler that will be called on success
request.done(function (response, textStatus, jqXHR) {
$('#overlay').hide()
$("#moreInfoMsg").html("Message Sent!");
});
// callback handler that will be called on failure
request.fail(function (jqXHR, textStatus, errorThrown) {
$('#overlay').hide()
// log the error to the console
alert(
"The following error occured: " +
textStatus, errorThrown
);
});
// callback handler that will be called regardless
// if the request failed or succeeded
request.always(function () {
// reenable the inputs
$inputs.prop("disabled", false);
});
// prevent default posting of form
event.preventDefault();
}
</script>
I have a view (Index.cshtml) with a grid (Infragistics JQuery grid) with an imagelink. If a user clicks on this link the following jquery function will be called:
function ConfirmSettingEnddateRemarkToYesterday(remarkID) {
//Some code...
//Call to action.
$.post("Home/SetEnddateRemarkToYesterday", { remarkID: remarkID }, function (result) {
//alert('Succes: ' + remarkID);
//window.location.reload();
//$('#remarksgrid').html(result);
});
}
Commented out you can see an alert for myself and 2 attempts to refresh the view. The location.reload() works, but is basically too much work for the browser. The .html(result) posts the entire index.cshtml + Layout.cshtml double in the remarksgrid div. So that is not correct.
This is the action it calls (SetEnddateRemarkToYesterday):
public ActionResult SetEnddateRemarkToYesterday(int remarkID) {
//Some logic to persist the change to DB.
return RedirectToAction("Index");
}
This is the action it redirects to:
[HttpGet]
public ActionResult Index() {
//Some code to retrieve updated remarks.
//Remarks is pseudo for List<Of Remark>
return View(Remarks);
}
If I don't do window.location.reload after the succesfull AJAX post the view will never reload. I'm new to MVC, but i'm sure there's a better way to do this. I'm not understanding something fundamental here. Perhaps a nudge in the right direction? Thank you in advance.
As you requesting AJAX call, you should redirect using its response
Modify your controller to return JSONResult with landing url:
public ActionResult SetEnddateRemarkToYesterday(int remarkID) {
//Some logic to persist the change to DB.
var redirectUrl = new UrlHelper(Request.RequestContext).Action("Index", "Controller");
return Json(new { Url = redirectUrl });
}
JS Call:
$.post("Home/SetEnddateRemarkToYesterday", { remarkID: remarkID }, function (result) {
window.location.href = result.Url
});
After Ajax post you need to call to specific Url..
like this..
window.location.href = Url
When using jQuery.post the new page is returned via the .done method
jQuery
jQuery.post("Controller/Action", { d1: "test", d2: "test" })
.done(function (data) {
jQuery('#reload').html(data);
});
HTML
<body id="reload">
For me this works. First, I created id="reload" in my form and then using the solution provided by Colin and using Ajax sent data to controller and refreshed my form.
That looks my controller:
[Authorize(Roles = "User")]
[HttpGet]
public IActionResult Action()
{
var model = _service.Get()...;
return View(model);
}
[Authorize(Roles = "User")]
[HttpPost]
public IActionResult Action(object someData)
{
var model = _service.Get()...;
return View(model);
}
View:
<form id="reload" asp-action="Action" asp-controller="Controller" method="post">
.
.
.
</form>
Javascript function and inside this function I added this block:
$.ajax({
url: "/Controller/Action",
type: 'POST',
data: {
__RequestVerificationToken: token, // if you are using identity User
someData: someData
},
success: function (data) {
console.log("Success")
console.log(data);
var parser = new DOMParser();
var htmlDoc = parser.parseFromString(data, 'text/html'); // parse result (type string format HTML)
console.log(htmlDoc);
var form = htmlDoc.getElementById('reload'); // get my form to refresh
console.log(form);
jQuery('#reload').html(form); // refresh form
},
error: function (error) {
console.log("error is " + error);
}
});
I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code???
<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();
paymentApplicationRefund.City.Trim();
paymentApplicationRefund.Contact.Trim();
paymentApplicationRefund.State.Trim();
paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}
else
{
return null;
}
}
You probably just need to tell it to expect JSON data back. By default it assumes it's HTML.
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
}, 'json');
I prefer sending Json to a ActionResult with my DTO as the parameter and use the JsonValueProviderFactory do the deserialization for me.
Sending JSON to an ASP.NET MVC Action Method Argument
Try this...
Add the ".change()" at the end of the function.
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
.....
}).change();
});
I am trying to change a value in a table from one view, and then redirect to another view using Flash FSCommand and Json, using the following code:
if (command == "nameClip") {
var url = '<%= Url.Action("Index", "Home") %>';
var clip = [args];
try {
$.post(url, {
MovieName: clip
}, function(data) {
;
}, 'json');
} finally {
// window.location.href = "/Demo/SWF";
}
}
In the controller:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(SWF movietoplay) {
var oldmovie = (from c in db.SWFs where c.ID == "1" select c).FirstOrDefault();
var data = Request.Form["MovieName"].ToString();
oldmovie.SWFName = data;
db.SubmitChanges();
return RedirectToAction("Show");
}
All works well except Redirect!!
You need to perform the redirect inside the AJAX success callback:
$.post(url, { MovieName: clip }, function(data) {
window.location.href = '/home/show';
}, 'json');
The redirect cannot be performed server side as you are calling this action with AJAX.
Also you indicate in your AJAX call that you are expecting JSON from the server side but you are sending a redirect which is not consistent. You could modify the controller action to simply return the url that the client needs to redirect to using JSON:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(SWF movietoplay)
{
...
return Json(new { redirectTo = Url.Action("show") });
}
and then:
$.post(url, { MovieName: clip }, function(data) {
window.location.href = data.redirectTo;
}, 'json');
