I'm trying to pass an array from javascript back into my MVC app. There is a console.log(selected) in the javascript and it outputs an array of data:
["<img src="https://owlexpress.kennesaw.edu/stugifs/open.gif">", "MATH 1190/01 - Calculus I", "84528", " 4.000", "Full Term", "40", "34", "6", "0", "0", "0", "Kennesaw Campus", "Classroom - 100%", "Mathematics & StatisticsRoom 108", "8:00 am - 9:10 amLecture", "Aug 17, 2015", "Dec 14, 2015", "Xiaohui Rebecca Shi (P)", ""]
But when the breakpoint in the controller hits I see that selectedClassesArray == null
Javascript:
$('#WatchButton').on('click', function (e) {
var selected = [];
$("tr.selected").each(function () {
$(this).find('td').each(function(){
selected.push($(this).html());
});
});
console.log(selected);
$.ajax({
type: "POST",
url: "/ClassSearch/watchClasses",
// I have tried setting data both ways with the same result:
//data: { selectedClassesArray: selected },
data: [selected],
traditional: true,
success: function (data) { alert("SUCCESS"); }
});
});
ViewModel:
public class SelectedClassesArray
{
public string[] arrayOfClasses { get; set; }
}
Controller ACtion:
//Had to set ValidateInput to false since one of the strings contains < (it errored without this)
[HttpPost, ValidateInput(false)]
public ActionResult watchClasses(IEnumerable<SelectedClassesArray> selectedClassesArray)
{ //Breakpoint here shows that selectedClassesArray is null
foreach (var item in selectedClassesArray)
{
Console.WriteLine(item.ToString());
}
return View();
}
Your action is expecting a List of arrays:
watchClasses(IEnumerable<SelectedClassesArray> selectedClassesArray)
You probably want to get only the array, which is in the view model:
watchClasses(SelectedClassesArray selectedClassesArray)
And what #taxicala said makes sense, try passing only the array, not an array inside another array:
data: { selectedClassesArray: selected }
The posted property name must match the view model parameter's name.
Did you try:
$.ajax({
type: "POST",
url: "/ClassSearch/watchClasses",
// I have tried setting data both ways with the same result:
//data: { selectedClassesArray: selected },
data: selected,
traditional: true,
success: function (data) { alert("SUCCESS"); }
});
Or perhaps the traditional serialization is failing:
$.ajax({
type: "POST",
url: "/ClassSearch/watchClasses",
// I have tried setting data both ways with the same result:
//data: { selectedClassesArray: selected },
data: { selectedClassesArray: selected },
traditional: false,
success: function (data) { alert("SUCCESS"); }
});

I have a sapui5 application:
I have an xml view called "Submission.view and corresponding controller called "submission.controller".
I have method which is fetching some question id's from a service using certain input parameters.
For example if i pass "null" and "previous" it gives me a json response as:
[
{
"__type__": "QuestionOutput",
"QuestionType": "",
"QuestionID": 51,
"YesNo": "",
"Mandatory": false
},
{
"__type__": "QuestionOutput",
"QuestionType": "",
"QuestionID": 52,
"YesNo": "",
"Mandatory": false
},
{
"__type__": "QuestionOutput",
"QuestionType": "",
"QuestionID": 53,
"YesNo": "",
"Mandatory": false
}
]
Now i want to pass each of the questionid's like 51,52,53 to another method which calls a rest service to fetch the descriptions for the above questionid's from hana data base.
getBpmRules: function(sToken, sQuestionId, sAnswer) {
var that = this;
this.showBusy();
jQuery.ajax({
type: "POST",
contentType: "application/json",
dataType: "json",
async: false,
url: "/bpmrulesruntime/rules-service/v1/rules/invoke?rule_service_name=SelfServiceRule::QuestionRuleService",
context: that,
xhrFields: {
withCredentials: true
},
headers: {
'X-CSRF-Token': sToken
},
data: JSON.stringify([{
"__type__": "QuestionInput",
"QuestionID": "" + sQuestionId + "",
"Answer": "" + sAnswer + ""
}]),
error: function(jqXHR, textStatus, errorThrown) {
that.hideBusy();
sap.m.MessageBox.alert(textStatus + " - " + errorThrown + " : " + jqXHR.responseText, {
icon: sap.m.MessageBox.Icon.ERROR,
title: this.getText("error")
});
},
success: function(data, textStatus, jqXHR) {
var questiondesc = [];
if (data.length !== 0) {
var desc = [];
//this.getModel("questionModel").setProperty("/questionDescription", data);
for (var i = 0; i < data.length; i++) {
desc = that.getQuestionDescriptionById(data[i].Question, sToken);
}
}
that.hideBusy();
this._oManagerBusy.setVisible(false);
this._showSendDialog();
}
});
}
After getting the json data i am just looping and passing the question ids to another method to get the description for each question which again is a json response.
getQuestionDescriptionById: function(id, token) {
jQuery.sap.log.debug("Getting question by Id");
var questionDescription = [];
this.getComponent().ajax({
method: "GET",
url: "/selfservice/rest/question/admin/questionid/" + id,
contentType: "application/json",
context: this,
headers: {
'X-CSRF-Token': token
},
error: function(jqXHR, textStatus, errorThrown) {
this.getModel("resources").setProperty("/ticketSubmitMessage", this.getModel("i18n").getProperty("sendDialogText"));
this._oManagerBusy.setVisible(false);
this._showSendDialog();
},
success: function(data, textStatus, jqXHR) {
//oModel.loadData(“json/Item.json”);
// this.getView().setModel(new JSONModel(data.question,"questionDescription"));
if (data.length !== 0) {
questionDescription.push(data);
}
}
});
return questionDescription;
},
Issue:
I am not able to set the model for the view with the json response that i am getting from the second method since for each questionid it goes to the next method "getQuestionDescriptionById" and even though i return the response..it doesn't work.
Can you please let me know how to set a json model for each response that i get for each question id.
Thanks !!
I am using CodeIgniter. In my Controller file, I have JSON containing an array (as a result of calling different API's):
{
"Specialities": [{
"SpecialityID": 1,
"SpecialityName": "Eye Doctor"
},{
"SpecialityID": 2,
"SpecialityName": "Chiropractor"
},{
"SpecialityID": 3,
"SpecialityName": "Primary Care Doctor"
}]
}
In controller, I wrote
echo $response[0];
with this line of code I can easily iterate through json object in jquery:
$.ajax({
type: 'GET',
url: 'http://localhost/rest_project/main/res',
dataType: 'JSON',
crossDomain: true,
xhrFields: { withCredentials: true },
success: function (data){
$.each(data.Specialities,function(key,value){
console.log(value.SpecialityName);
});
}
});
but if I pass the array:
echo json_encode($response);
Then I am unable to get the results:
$.ajax({
type: 'GET',
url: 'http://localhost/rest_project/main/res',
dataType: 'JSON',
crossDomain: true,
xhrFields: { withCredentials: true },
success: function (data){
$.each(data[0].Specialities,function(key,value){
console.log(value.SpecialityName);
});
}
});
Can someone help me please?
It seems that your jsonObject is not an array and each works with array only.
//Check if your jsonObject is array, if not then make it.
if (!$.isArray(jsonObject)) {
jsonObject = [jsonObject];
}
$.each(jsonObject, function(key, value){
console.log("FULL NAME " + value.FullName);
});
var data = {
"Specialities": [{
"SpecialityID": 1,
"SpecialityName": "Eye Doctor"
},{
"SpecialityID": 2,
"SpecialityName": "Chiropractor"
},{
"SpecialityID": 3,
"SpecialityName": "Primary Care Doctor"
}]
};
//Convert your jsonObject to array for each
if (!$.isArray(data)) {
data = [data];
}
$.each(data[0].Specialities,function(key,value){
console.log(value.SpecialityName);
});

I want to bind json data returned by API to dropdownlist.
but unable to fetch value id and name.
Json Format :
{
"categories": [
{
"categories": {
"id": 1,
"name": "CatOne"
}
},
{
"categories": {
"id": 2,
"name": "CatTwo"
}
}
]
}
I am returning JsonResult, using
return Json(responseData, JsonRequestBehavior.AllowGet);
and in Jquery call ,I am using
$.ajax({
type: "POST",
url: "/Home/City",
contentType: "application/json; charset=utf-8",
global: false,
async: false,
dataType: "json",
success: function (jsonObj) {
var listItems = "";
//here I want to get id and name
});
}
});
You can populate dropdown from your json like following.
var json = {
"categories": [
{ "categories": { "id": 1, "name": "CatOne" } },
{ "categories": { "id": 2, "name": "CatTwo" } }
]
}
$.each(json.categories, function () {
$('select').append('<option value="' + this.categories.id + '">' + this.categories.name + '</option>')
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select></select>
You can just stick a break point (or debugger; statement) inside your success callback. Then you can inspect your jsonObj and it'll tell you exactly what you need to know.
In this case, you should be able to iterate on jsonObj.categories, and your id and name properties will be accessible via jsonObject.categories[i].categories.id and jsonObject.categories[i].categories.name
So your success method will look something like:
for(var i = 0; i < jsonObj.categories.length; i++) {
var category = jsonObj.categories[i].categories;
var id = category.id;
var name = category.name;
}
I would also suggest formatting your json differently, as other answers have suggested.
I am trying to pass three products through the shopify ajax api. It sends over the variant id and quantity but not the properties. the code is below. if I add request.properties to the Shopify.addItem function it stops after one item and gives me a pop saying that one item has been added to the cart. It does not add the other two items nor does it redirect. If I remove request.properties from the Shopify.addItem function it adds all three items to the cart but with no properties.
FINAL CODE Revised from #miglio code
var FreeTrial={
data:[],
ini:0,
total:0,
addItem:function(qty,id,properties,callback) {
var params = {quantity:qty,id:id};
if(properties != false){
params.properties = properties;
}
$.ajax({
type: 'POST',
url: '/cart/add.js',
dataType: 'json',
async:false,
data: params,
success: function(){
if(typeof callback === 'function'){
callback();
}
},
error: function(){}
});
},
recursive:function(){
FreeTrial.addItem(FreeTrial.data[FreeTrial.ini].qty,FreeTrial.data[FreeTrial.ini].id,FreeTrial.data[FreeTrial.ini].properties,function(){
//console.log(FreeTrial.data[FreeTrial.ini]);
FreeTrial.ini += 1;
if(FreeTrial.ini < FreeTrial.total){
FreeTrial.recursive();
}else{
//return false;
document.location.href = '/cart';
}
});
},
begin:function(){
/* SET YOUR ARRAY QTY's' ID's*/
FreeTrial.data = [
{
"qty": '1',
"id": 'VARIANT_ID_GOES_HERE',
"properties": false
},
{
"qty": '1',
"id": 'VARIANT_ID_GOES_HERE',
"properties": false
},
{
"qty": '1',
"id": 'VARIANT_ID_GOES_HERE',
"properties": false
},
{
"qty": '1',
"id": 'VARIANT_ID_GOES_HERE',
"properties": false
},
{
"qty": '1',
"id": 'VARIANT_ID_GOES_HERE',
"properties": {
"recurring_price": "200.00",
"shipping_interval_frequency": "30",
"shipping_interval_unit_type": "days",
"subscription_id": "12599"
}
}
];
FreeTrial.total = FreeTrial.data.length;
FreeTrial.recursive();
}
}
FreeTrial.begin();
To add properties I use this function and work fine for me.
addItem=function(qty,id,properties,callback) {
var params = {quantity:qty,id:id};
if(properties != false){
params.properties = properties;
}
$.ajax({
type: 'POST',
url: '/cart/add.js',
dataType: 'json',
data: params,
success: function(){
if(typeof callback === 'function'){
callback();
}
},
error: function(){}
});
}
//Example :
var qty = 1;
var id = 123456;//variant_id
var properties: {
"recurring_price": "12",
"shipping_interval_frequency": "34",
"shipping_interval_unit_type": "56",
"subscription_id": "78"
}
//
addItem(qty,id,properties,function(){
console.log('done');
});
Well, I did this code for multiple items and a save in a gist:
multiple add to cart
Any POST to the endpoint url: '/cart/add.js', can include properties. If the properties are setup correctly, it works like a charm. You can assign as many properties to a variant as you want. Has been working for what, 5 years now? This function has been working for that long at least... no trouble.
addItemWithProperties: function(variant_id, quantity, properties, callback) {
var quantity = quantity || 1;
if(properties) {
var data = properties.join("&")+"&quantity="+quantity+"&id="+variant_id;
} else {
var data = "quantity="+quantity+"&id="+variant_id;
}
var params = {
type: "POST",
url: "/cart/add.js",
data: data,
dataType: "json",
success: function(line_item) {
if((typeof callback) === "function") {
callback(line_item)
} else {
Shopify.onItemAdded(line_item)
}
},
error: function(XMLHttpRequest, textStatus) {
Shopify.api.onError(XMLHttpRequest, textStatus)
}
};
$.ajax(params)
},
edit. I guess you could do the call manually
add to cart
Considering the Shopify.addItem() function is, straight off their API I'm not sure you can simply add a parameter like that.
My guess is that the extra parameter has the effect that the function doesn't run.
now I encounter a problem. I want to use ajax to show a datatable via using data coming from sql server database. Current state is I have used ajax to call a Handler.ashx to connect sql server and convert the data to json (using newtonsoft.json). In ajax, all json data has been recevied from Handler.ashx and stored in a variable "msg" which could be successfully showed on page. I want to put this "msg" into a datatable but failed all the time. I tried almost all methods online to set the datatable but still give different errors. I want to create a datatable in js and fill in my json data. But the result is either null or no data available in table.
Here is the codes and json data looks like.
js:
$(document).ready(function () {
$("#eventsButton").click(function () {
$.ajax({
type: "POST",
url: "../Handler.ashx",
//contentType: "application/json",
data: { postcode: $("#eventsPostcodeTextbox").val() },
cache: false,
success: function (msg) {
//for (var i in msg) {
// $("#eventGrid").append(msg[i]);
//}
//var jsonStr = JSON.stringify(msg);
document.getElementById("result").innerHTML = msg;
$('#eventtable').dataTable({
//"paging": false,
//"searching": false,
//"retrieve": true,
//"bProcessing": true,
//"data": msg.data,
//"datatype": "JSON",
//"ajax": "HandlerAll.ashx",
//"aaData": JSON.parse(msg),
//"ajax":
//"dataSrc":virtualTable
//"aoColumns": [
// { "mData": "ID" },
// { "mData": "FESTIVAL" },
// { "mData": "SUBURB" },
// { "mData": "POSTCODE" },
// { "mData": "WEBSITE" },
// { "mData": "DESCRIPTION" }
// ]
});
},
error: function (data) {
alert("Server error.");
}
})
});
});
json data (the size depends on the search condition, the table columns should have "ID","Festival" and so on, but no "virtualTable"):
{ "virtualTable": [ { "ID": "1", "FESTIVAL": "Antipodes Festival", "SUBURB": "Lonsdale Street, Melbourne", "POSTCODE": "3000", "WEBSITE": "http://www.antipodesfestival.com.au/", "DESCRIPTION": "The greek precinct in melbourne cbd will transform into a huge, free street festival with the hosting of the antipodes lonsdale street festival which will hold sway from 14 february 2015 to 15 february 2015." }, { "ID": "5", "FESTIVAL": "Boite Singers Festival", "SUBURB": "Victoria", "POSTCODE": "3000", "WEBSITE": "http://boite.com.au/index.php", "DESCRIPTION": "The boite singers festival brings you four days of vocal inspiration and sheer fun on the second weekend of january each year." } ] }
Since you get a JSON as reponse, I would try to convert it to JSON object, take the virtualTable part that it is a set of records in JSON and convert it to an array to add it to my table.
$(document).ready(function () {
$("#eventsButton").click(function () {
$.ajax({
type: "POST",
url: "../Handler.ashx",
// dataType: "json",
data: { postcode: $("#eventsPostcodeTextbox").val() },
success: function (msg) {
var jdata = $.parseJSON(msg);
jdata = jdata.virtualTable;
if (jdata.length != 0) {
var array_data = [];
var temp_array = [];
$(jdata).each(function(key, value) {
temp_array = [];
temp_array = [value.ID,
value.FESTIVAL,
value.SUBURB,
value.POSTCODE,
value.WEBSITE,
value.DESCRIPTION
];
array_data[array_data.length] = temp_array;
});
$('#eventtable').dataTable().fnAddData(array_data);
$('#eventtable').dataTable().fnDraw();
},
error: function (data) {
alert("Server error");
}
SOLUTION
Use the code below to initialize the table:
$('#eventtable').dataTable({
data: msg.virtualTable,
columns: [
{ data: "ID" },
{ data: "FESTIVAL" },
{ data: "SUBURB" },
{ data: "POSTCODE" },
{ data: "WEBSITE" },
{ data: "DESCRIPTION" }
]
});
