how to send two arrays to controller via ajax

I try to send two arrays to the controller, each array from a different class. But all I get is alert with an error message. What am I doing wrong? When I send only one array in ajax data, it is obtained fine in the first array of the controller.
my code js:
$("#Button2").click(function () {
var dict = new Array();
$(":checkbox").each(function () {
if ($(this).prop("checked")== true) {
var key = this.name
if ($("input[name = 'r" + key + "']").length) {
dict.push({
Code: key,
Reccomendation: $("input[name = 'r" + key + "']").prop("value"),
});
}
else{
dict.push({
Code: key,
Reccomendation: $(this).prop("value"),
});
}
}
}) //end function each
var dict2 = new Array();
dict2.push({
Mentioned: $("#yesno").val(),
FollowUp: $("#Follo").val(),
UpdateCode:5
})
$.ajax({
type: 'POST',
url: "#Url.Action("SavevisitSummary")",
traditional: true,
dataType: 'JSON',
contentType: 'application/json; charset=utf-8',
data: { 'a': JSON.stringify(dict), 'b': JSON.stringify(dict2) },
success: function () {
alert("sucssec")
},
error:function(){
alert("error")
}
})
})
controller looks like:
public ActionResult SavevisitSummary(Reccomendations[] a, Summary[] b) { }

oo practice, make function not hard coding, return data after bind change

I want to find a way,give a dom as parameter and get data, from image_preview.
and separate image_preview.model() and image_preivew.on_chage() is event handler
make image_preview reusable not hardcode inside
I espect I will call image_preview pass dom in parameter, and return src as response , then I can use repsponse do something like append ...
var image_preview = {
on_change: function(wrap_dom, input_dom) {
$(wrap_dom).on('change', input_dom, function(event) { // I have to use on change because there are possible the `input dom` is new append...
var el_obj = $(this)[0];
var form_data = new FormData();
var file_length = el_obj.files.length;
for (var i = 0; i < file_length; i++) {
form_data.append("file[]", el_obj.files[i]);
}
image_preview.model(form_data).done(function(response) {
// console.log(response); // this is work
return response;
});
});
},
model: function(form_data) {
return $.ajax({
url: uri_public+'/admin/ajax/preview_file',
type: 'POST',
data: form_data,
processData: false,
contentType: false,
// async: false
});
}
}
var app_thumbnail = {
preview_controller: function() {
var wrap_dom = '.thumbnail';
var input_dom = '.upload-form input';
var result = image_preview.on_change(wrap_dom, input_dom);
// pass result to render view like append dom....
},
render: function() {
},
}
app_thumbnail.preview_controller();

Here is the easiest thing you can do:
var image_preview = {
on_change: function(wrap_dom, input_dom) {
$(wrap_dom).on('change', input_dom, function(event) {
var el_obj = $(this)[0];
var form_data = new FormData();
var file_length = el_obj.files.length;
for (var i = 0; i < file_length; i++) {
form_data.append("file[]", el_obj.files[i]);
}
image_preview.model(form_data).done(function(response) {
app_thumbnail.preview_controller(response);
});
});
},
model: function(form_data) {
return $.ajax({
url: uri_public+'/admin/ajax/preview_file',
type: 'POST',
data: form_data,
processData: false,
contentType: false,
// async: false
});
}
}
var app_thumbnail = {
preview_controller: function(response) {
var wrap_dom = '.thumbnail';
var input_dom = '.upload-form input';
var result = response;
}
}
// If you want to initialize it.
// image_preview.on_change(..., ...);

Posting Array and Form Data to Controller - MVC Ajax

I've got an array of Objects in jQuery:
function customersList() {
this.selectedCustomers = [];
}
function customerObject(customerId, bookingId) {
this.customerId = customerId;
this.bookingId = bookingId;
}
I need to post this to my Controller:
[HttpPost]
public ActionResult CreateMultipleCasesFormPost(CreateMultipleCasesModel model)
{
return PartialView("_CreateMultipleCases", model);
}
My ViewModel:
public class CreateMultipleCasesModel
{
[Display(Name = "Selected Customers")]
public List<CustomerList> Customers { get; set; }
I need to pass the Array from jQuery and the Data from this Form to my Controller (My View Model contains other properties):
$('#createMultipleCasesForm')
This is my Post Form jQuery Code:
$('#createMultipleCasesBtn').click(function () {
var btn = $(this);
var mUrl = btn.data('actionurl');
var formModel = $('#createMultipleCasesForm').serializeArray();
var customerList = customersList.selectedCustomers();
var requestData = {
model: formModel,
Customers: customerList
};
var sData = JSON.stringify(requestData);
$.ajax({
url: mUrl,
type: 'POST',
dataType: 'json',
contentType: 'application/json; charset=utf-8',
data: sData,
success: function (response) {
debugger;
},
error: function (response) {
$('#ErrorMessage').html('<span class="icon black cross"></span>' + response.Message);
}
});
});
My Model from jQuery is not Binding either the Array of Customer Objects or the Form, What am I doing wrong here?
EDIT
What happens when I post Back my Form:

I found a solution this did the trick for me:
$('#createMultipleCasesBtn').click(function () {
var btn = $(this);
var mUrl = btn.data('actionurl');
var formModel = $('#createMultipleCasesForm').serializeObject();
formModel['Customers'] = customersList.selectedCustomers;
var sData = JSON.stringify(formModel);
$.ajax({
url: mUrl,
type: 'POST',
dataType: 'json',
contentType: 'application/json; charset=utf-8',
data: sData,
success: function (response) {
},
error: function (response) {
$('#ErrorMessage').html('<span class="icon black cross"></span>' + response.Message);
}
});
});
This Function Below Used from Answer Here: Convert form data to JavaScript object with jQuery
$.fn.serializeObject = function () {
var o = {};
var a = this.serializeArray();
$.each(a, function () {
if (o[this.name] !== undefined) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};

How to use q.js to chain backbone model?

I have the following:
var q = new app.models.OverwriteLineItemsProcess();
q.set('id', $("#process_id").val());
q.saveSource($("#source_quote").val());
q.lockSource();
saveSource is sending data to the backend using ajax. So is lockSource.
I want to execute in this SEQUENTIAL manner: saveSource >> lockSource.
How do I write the q.js to make it work?
By q.js, I mean https://github.com/kriskowal/q
UPDATE: added saveSource and lockSource
saveSource: function (quotation_id) {;
var type = "PUT";
var verb = "Updated";
var headers = {
'X-HTTP-Method-Override': type
};
var url = app.base_url + "/overwrite_line_items/" + this.id;
this.set('source_quote', quotation_id);
var data = this.toFormData();
var result = false;
var currentModel = this;
var settings = {
headers: headers,
type: type,
url: url,
data: data,
success: function(json) {
response = JSON && JSON.parse(json) || $.parseJSON(json);
console.log(response);
currentModel.lockSource();
$("#facebox-source-quote-status").html('<font color="green">SELECTED</font>');
},
error: function(response) {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
},
dataType: 'json'
};
$.ajax(settings).done(function() {
});
},
lockSource: function () {
var type = "PUT";
var verb = "Updated";
var headers = {
'X-HTTP-Method-Override': type
};
var url = app.base_url + "/quotations/is_editable/" + this.attributes.source_quote;
var data = this.toFormData();
var result = false;
var currentModel = this;
var settings = {
headers: headers,
type: type,
url: url,
data: data,
success: function(response) {
console.log(response);
},
error: function(response) {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
},
dataType: 'json'
};
$.ajax(settings).done(function() {
});
},

The jQuery.ajax function which you're using already returns a promise for its result. You just need to return that from your functions:
saveSource: function (quotation_id) {;
…
var settings = {
headers: headers,
type: type,
dataType: 'json', // jQuery will automatically parse it for you
url: url,
data: data
};
return $.ajax(settings).done(function() {
// ^^^^^^
$("#facebox-source-quote-status").html('<font color="green">SELECTED</font>');
// notice I did remove the currentModel.lockSource(); call from the callback
}, function() {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
});
},
lockSource: function () {
…
var settings = // analoguous, no callbacks here
return $.ajax(settings).fail(function(response) {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
});
}
Now you can easily chain them:
var q = new app.models.OverwriteLineItemsProcess();
q.set('id', $("#process_id").val());
q.saveSource($("#source_quote").val()).then(function(saveResponse) {
console.log(saveResponse);
return q.lockSource();
}).done(function(lockResponse) {
console.log(lockResponse);
});
You don't even need Q for that. If you want to use it, wrap the $.ajax() calls in a Q() invocation, as explained in the Converting JQuery Promises to Q section of the docs.

Want to get an access_token from Twitter Oauth api using oauth.js plugin

I am trying to get a Twitter access token from their oauth api. The plugin I am using is this https://code.google.com/p/oauth/source/browse/#svn%2Fcode%2Fjavascript. So far I only get "401 failed to validate signature and token".
Strange thing is that my ajax call becomes 'GET' request even though I set type:'POST'. Seems like jquery is changing the type from POST to GET. I don't know why it does that. I am running it on my Mac. I appreciate your help/hints/suggestions/advises. Thanks!
$(function() {
function myCallback(resp) {
console.log(resp);

return array_map([ // TODO
