How do I populate a list field in a model from javascript?

I have a Kendo.MVC project. The view has a model with a field of type List<>. I want to populate the List from a Javascript function. I've tried several ways, but can't get it working. Can someone explain what I'm doing wrong?
So here is my model:
public class Dashboard
{
public List<Note> ListNotes { get; set; }
}
I use the ListNotes on the view like this:
foreach (Note note in Model.ListNotes)
{
#Html.Raw(note.NoteText)
}
This works if I populate Model.ListNotes in the controller when the view starts...
public ActionResult DashBoard(string xsr, string vst)
{
var notes = rep.GetNotesByCompanyID(user.ResID, 7, 7);
List<Koorsen.Models.Note> listNotes = new List<Koorsen.Models.Note>();
Dashboard employee = new Dashboard
{
ResID = intUser,
Type = intType,
FirstName = user.FirstName,
LastName = user.LastName,
ListNotes = listNotes
};
return View(employee);
}
... but I need to populate ListNotes in a Javascript after a user action.
Here is my javascript to make an ajax call to populate ListNotes:
function getReminders(e)
{
var userID = '#ViewBag.CurrUser';
$.ajax({
url: "/api/WoApi/GetReminders/" + userID,
dataType: "json",
type: "GET",
success: function (notes)
{
// Need to assign notes to Model.ListNotes here
}
});
}
Here's the method it calls with the ajax call. I've confirmed ListNotes does have the values I want; it is not empty.
public List<Koorsen.Models.Note> GetReminders(int id)
{
var notes = rep.GetNotesByCompanyID(id, 7, 7);
List<Koorsen.Models.Note> listNotes = new List<Koorsen.Models.Note>();
foreach (Koorsen.OpenAccess.Note note in notes)
{
Koorsen.Models.Note newNote = new Koorsen.Models.Note()
{
NoteID = note.NoteID,
CompanyID = note.CompanyID,
LocationID = note.LocationID,
NoteText = note.NoteText,
NoteType = note.NoteType,
InternalNote = note.InternalNote,
NoteDate = note.NoteDate,
Active = note.Active,
AddBy = note.AddBy,
AddDate = note.AddDate,
ModBy = note.ModBy,
ModDate = note.ModDate
};
listNotes.Add(newNote);
}
return listNotes;
}
If ListNotes was a string, I would have added a hidden field and populated it in Javascript. But that didn't work for ListNotes. I didn't get an error, but the text on the screen didn't change.
#Html.HiddenFor(x => x.ListNotes)
...
...
$("#ListNotes").val(notes);
I also tried
#Model.ListNotes = notes; // This threw an unterminated template literal error
document.getElementById('ListNotes').value = notes;
I've even tried refreshing the page after assigning the value:
window.location.reload();
and refreshing the panel bar the code is in
var panelBar = $("#IntroPanelBar").data("kendoPanelBar");
panelBar.reload();
Can someone explain how to get this to work?
I don't know if this will cloud the issue, but the reason I need to populate the model in javascript with an ajax call is because Model.ListNotes is being used in a Kendo Panel Bar control and I don't want Model.ListNotes to have a value until the user expands the panel bar.
Here's the code for the panel bar:
#{
#(Html.Kendo().PanelBar().Name("IntroPanelBar")
.Items(items =>
{
items
.Add()
.Text("View Important Notes and Messages")
.Expanded(false)
.Content(
#<text>
#RenderReminders()
</text>
);
}
)
.Events(e => e
.Expand("getReminders")
)
)
}
Here's the helper than renders the contents:
#helper RenderReminders()
{
if (Model.ListNotes.Count <= 0)
{
#Html.Raw("No Current Messages");
}
else
{
foreach (Note note in Model.ListNotes)
{
#Html.Raw(note.NoteText)
<br />
}
}
}
The panel bar and the helpers work fine if I populate Model.ListNotes in the controller and pass Model to the view. I just can't get it to populate in the javascript after the user expands the panel bar.

Perhaps this will do it for you. I will provide a small working example I believe you can easily extend to meet your needs. I would recommend writing the html by hand instead of using the helper methods such as #html.raw since #html.raw is just a tool to generate html in the end anyways. You can write html manually accomplish what the helper methods do anyway and I think it will be easier for you in this situation. If you write the html correctly it should bind to the model correctly (which means it won't be empty on your post request model) So if you modify that html using javascript correctly, it will bind to your model correctly as well.
Take a look at some of these examples to get a better idea of what I am talking about:
http://www.hanselman.com/blog/ASPNETWireFormatForModelBindingToArraysListsCollectionsDictionaries.aspx
http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/
So to answer your question...
You could build a hidden container to hold your list values like this (make sure this container is inside the form):
<div id="ListValues" style="display:none">
</div>
Then put the results your ajax post into a javascript variable (not shown).
Then in javascript do something like this:
$('form').off('submit'); //i do this to prevent duplicate bindings depending on how this page may be rendered futuristically as a safety precaution.
$('form').on('submit', function (e) { //on submit, modify the form data to include the information you want inside of your ListNotes
var data = getAjaxResults(); //data represents your ajax results. You can acquire and format that how you'd like I will use the following as an example format for how you could save the results as JSON data: [{NoteID ="1",CompanyID ="2"}]
let listLength = data.length;
for (let i = 0; i < listLength; i++) {
$('#ListValues').append('<input type="text" name="ListNotes['+i+'].NoteID " value="' + data.NoteID +'" />')
$('#ListValues').append('<input type="text" name="ListNotes['+i+'].CompanyID " value="' + data.CompanyID +'" />')
//for your ajax results, do this for each field on the note object
}
})
That should do it! After you submit your form, it should automatically model bind to you ListNotes! You will be able to inpsect this in your debugger on your post controller action.

AngularJS - Get printed value from scope inside an attribute?

I'm currently working on an AngularJS project and I got stuck in this specific requirement.
We have a service that has all the data, DataFactoryService. Then, I have a controller called DataFactoryController that is making the magic and then plot it in the view.
<div ng-repeat = "list in collection">
{{list.name}}
...
</div>
Now, we have a requirement that pass multiple data into one element. I thought an "ng-repeat" would do, but we need to have it inside an element attribute.
The scenarios are:
At one of the pages, we have multiple lists with multiple data.
Each data has a unique code or ID that should be passed when we do an execution or button click.
There are instances that we're passing multiple data.
Something like this (if we have 3 items in a list or lists, so we're passing the 3 item codes of the list):
<a href = "#" class = "btn btn-primary" data-factory = "code1;code2;code3;">
Submit
</a>
<a href = "#" class = "btn btn-default" data-factory = "code1;code2;code3;">
Cancel
</a>
In the example above, code1,code2,code3 came from the list data. I tried several approach like "ng-repeat", "angular.each", array, "ng-model" but I got no success.
From all I've tried, I knew that "ng-model" is the most possible way to resolve my problem but I didn't know where to start. the code below didn't work though.
<span ng-model = "dataFactorySet.code">{{list.code}}</span>
{{dataFactorySet.code}}
The data is coming from the service, then being called in the controller, and being plot on the HTML page.
// Controller
$scope.list = dataFactoryService.getAllServices();
The data on the list are being loaded upon initialization and hoping to have the data tags initialized as well together with the list data.
The unique code(s) is/are part of the $scope.list.
// Sample JSON structure
[
{ // list level
name: 'My Docs',
debug: false,
contents: [ // list contents level
{
code: 'AHDV3128',
text: 'Directory of documents',
...
},
{
code: 'AHDV3155',
text: 'Directory of pictures',
...
},
],
....
},
{ // list level
name: 'My Features',
debug: false,
contents: [ // list contents level
{
code: 'AHGE5161',
text: 'Directory of documents',
...
},
{
code: 'AHGE1727',
text: 'Directory of pictures',
...
},
],
....
}
]
How can I do this?
PLUNKER -> http://plnkr.co/edit/Hb6bNi7hHbcFa9RtoaMU?p=preview

The solution for this particular problem could be writing 2 functions which will return the baseId and code with respect to the list in loop.
I would suggest to do it like below
Submit
Cancel
//inside your controller write the methods -
$scope.getDataFactory = function(list){
var factory = list.map( (a) => a.code );
factory = factory.join(";");
return factory;
}
$scope.getDataBase= function(list){
var base= list.map( (a) => a.baseId);
base= base.join(";");
return base;
}
Let me know if you see any issue in doing this. This will definitely solve your problem.

You don't really have to pass multiple data from UI if you are using Angular.
Two-way data binding is like blessing which is provided by Angular.
check your updated plunker here [http://plnkr.co/edit/mTzAIiMmiVzQfSkHGgoU?p=preview]1
What I have done here :
I assumed that there must be some unique id (I added Id in the list) in the list.
Pass that Id on click (ng-click) of Submit button.
You already have list in your controller and got the Id which item has been clicked, so you can easily fetch all the data of that Id from the list.
Hope this will help you... cheers.

So basing from Ashvin777's post. I came up with this solution in the Controller.
$scope.getFactoryData = function(list) {
var listData = list.contents;
listData = listData.map(function(i,j) {
return i.code;
});
return listData.join(';');
}

How to submit dynamically created hidden variables using Jquery

I have created a dynamic table. DEMO to my project.
I have placed this dynamic table in the form under a div named 'box'
<div id="box">
</div>.
I am creating dynamic hidden variables table using Jquery which I need to store in DB. This is how I am creating the hash to submit to server.
criteria = $('form_name').serialize(true);
criteria = Object.toJSON(criteria);
// Build the object to store the parameters for the AJAX post request
parameters = {
title : $('report_title').value,
description : $('report_description').value,
criteria : criteria
}
// Make the AJAX post request
new Ajax.Request( URL, {
method: 'post',
parameters: parameters,
onSuccess: function( response ) {
$('messageSpan').innerHTML = response.responseText;
$('spinner').style.display='none';
}
});
I am not able to capture the dynamically created values in the criteria.
How to solve this?
In the dynamically created section, I tried adding a submit button and see if the values can be fetched. I am able to fetch and iterate all the hidden variables.
$('#jquerysaveButton').click(function(){
jsonObj = [];
$("input[id=rubric_cell]").each(function () {
var id = "cell_" + row + "_" + col;
item = {}
item["id"] = id;
item["selected_rubric"] = $(this).val();
jsonObj.push(item);
});
console.log(jsonObj); //I am getting the required values here
});
How to get these values in the criteria = $('form_name').serialize(true);. Am I doing some thing wrong? Please help me. thanks in advance.
DEMO to my project

You need to make sure that your hidden input fields have a name attribute set otherwise $.serialize will not process them.

difficulty getting list of values from series of input elements inside table rows

I'm completely stumped. Granted, in java script i'm like that kid trying to jam a square peg into a round hole.
My high level objective: The admins want the ability to edit text surrounding some text boxes, as well as the ability to add and remove 'paragraph'. The reporters and users want the values that are in the textboxes to be used in comparisons, etc (which is the original functionality).
My Solution: This project uses a pretty messy value - attribute table (called an EAV?), which now has fields with associated fields and is self referencing. I decided to leverage this to minimize changes to the database, so the admin essentially creates a string, denotes the places a text box belongs using '{}', and assigns a name to the attribute into text boxes that appear directly below the paragraph.
My Problem: Textboxes generate fine, as soon as the admin stops typing the "{}" count is checked client side, and the correct number of textboxes are added/removed in rows below. However, when the "change" mode (and thereby save the new string) I also want to save the attribute names they selected. I can't seem to get the actual value out of the input. The java script below sends null to elementList. Closer inspection indicates that var fieldNames is getting two elements of "undefined" so it makes sense that I'm getting null. Its also apparent that Its hitting something, becuase the number aligns with there being two 'nameField' rows.
DOM (Hemed down to the essentials)
<tr data-editMode="TextMode" data-ordinal="0">
....
<td>
<a class="changeMode">
<tr class="nameField">
<td colspan='4'>
<input type="text" value="Testing">
<tr class="nameField">
....
Javascript
function getAssociatedTr(row) {
var associatedRows = [];
associatedRows.push(row);
row = row.next('tr');
var hasAnother = true;
while (hasAnother == true) {
if (row != null && row.hasClass("nameField")) {
associatedRows.push(row);
row = row.next('tr');
} else {
hasAnother = false;
}
}
return associatedRows;
}
$(".changeMode").live("click", function () {
var options = $(this).data("options");
var theRow = $(this).closest('tr');
var rows = getAssociatedTr(theRow);
var fieldNames = new Array();
rows.splice(0, 1);
for (var index = 0; index < rows.length; index++) {
{
fieldNames.push(rows[index].next('.nameField').val());
}
}
$(".modal-header", c.rowsModal).html("<h3>Changing edit mode" + options.table + "</h3>");
c.rowsModal.modal("show");
$.ajax({
type: "POST",
traditional: true,
data: { "Name": options.table, "Ordinal": options.row, "EditMode": options.editMode, "ElementNames": fieldNames },
url: "/contracts/changeeditmode/" + c.id.val(),
success: function (data) {
theRow.replaceWith(data);
$.validator.unobtrusive.parse("#supplementForm");
c.rowsModal.modal("hide");
for (j = rows.length - 1 ; j >= 0; j--) {
rows[j].remove();
}
}
});
});
Server side
public ActionResult ChangeEditMode(long id, AddTrackedRowViewModel model,
string editMode, List<string> elementNames)
{
}
As a side note, I'm open to constructive criticism on the JavaScript.
EDIT
I have updated the line to
fieldNames.push(rows[index].nextAll('input').first().val());
But still getting undefined.
SOLUTION
fieldNames.push(rows[index].find("input[type=text]").val());

In this line:
fieldNames.push(rows[index].next('.nameField').val());
you are using the selector ".nameField", but this get a "tr" element, if you want the textbox you need this:
fieldNames.push(rows[index].next('.valid').val());
or using other selector that give you the textbox.

Showing dynamic links inside a table

In jquery, how can I show a link that is generated on the fly inside a table?
I will have the link stored in my database, but I want it to be shown by a name and then take me to the correct link accordingly.
I have an array of strings like [ {Name1:Link1} ] stored, and I want it to be shown inside the table as Name1 linking to Link1.
Please tell me how to do so.

You need to store them in a (object) map instead of an array.
var linksMap = {
'google': 'http://google.com',
'stackoverflow': 'http://stackoverflow.com',
'jquery': 'http://jquery.com'
};
Then, assuming that you've the following table,
<table id="links">
<tr><td>google</td></tr>
<tr><td>stackoverflow</td></tr>
<tr><td>jquery</td></tr>
</table>
you can use the following jQuery script to create links and put them in the cells:
$('#links>tbody td:nth-child(1)').each(function() {
var $td = $(this);
var name = $td.text();
var link = linksMap[name];
var $a = $('<a>').attr('href', link).text(name);
$td.html($a);
});
