Add/Remove values to field from checkbox values in Javascript

I have two fields: one is a checkbox (built with Scala), one is an input/text field. I am trying to add and remove values from the checkbox to the input field. I am trying to take multiple values and string together with a comma.
Here are my HTML fields:
<div class="column column1">
#for(service <- servicesList) {
<label><input type="checkbox" name="selectServices" value=#service.name><span>#service.name</span></label>
}
</div>
<input name="services" id="services">
I am using jQuery in a tag to try to record the onchange event:
$(document).ready(function(){
var $services = $('#services');
var $selectServices = $('#selectServices');
$selectServices.change(function(){
for (var i = 0, n = this.length; i < n; i++) {
if (this[i].checked) {
$services.val($services.val() + this[i].value);
}
else {
$services.val($services.val().replace(this[i].value, ""));
}
}
});
});
However, it seems that this will not "fire" when checking and unchecking the checkbox. I do not receive any errors or messages, so I am guessing it is not working or the code is incorrect.
I appreciate the help!

Try this example, you don't have to search and replace all the time, just set a new value:
$(function() {
$('input[name=selectServices]').on('change', function() {
$('#services').val($('input[name=selectServices]:checked').map(function() {
return this.value;
}).get());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="column column1">
<label>
<input type="checkbox" name="selectServices" value='1'><span>1</span>
</label>
<label>
<input type="checkbox" name="selectServices" value='2'><span>2</span>
</label>
<label>
<input type="checkbox" name="selectServices" value='3'><span>3</span>
</label>
<label>
<input type="checkbox" name="selectServices" value='4'><span>4</span>
</label>
</div>
<input name="services" id="services">
does the $(function() {} go into the $(document).ready(function(){}?
No, it is short-hand or equivalent for the same.

This is just an addition on #Halcyon his answer so you can create a nicer list, in stead of the replace method. #Halcyon is most definitely the correct answer why your check boxes aren't working. This is just a better solution handling values.
$(document).ready(function(){
var $services = $('#services');
var $selectServices = $('.selectServices');
$selectServices.change(function(){
updateServices();
});
function updateServices() {
var allVals = [];
$('.selectServices:checked').each(function() {
allVals.push($(this).val());
});
$services.val(allVals);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="column column1">
<label><input class="selectServices" type="checkbox" name="selectServices[]" value="Foo"><span>Foo</span></label>
<label><input class="selectServices" type="checkbox" name="selectServices[]" value="Bar"><span>Bar</span></label>
<label><input class="selectServices" type="checkbox" name="selectServices[]" value="FooBar"><span>FooBar</span></label>
</div>
<input name="services" id="services">

$('#selectServices') selects by id, there are no elements with that id. Ids must be unique so you can't use them in this case. I also wouldn't recommend using name because input elements should have unique names. You can use class:
<label><input type="checkbox" class="selectServices" ...
Then use .selectServices in jQuery. And:
var $selectServices = $('.selectServices');
$selectServices.change(function(){
if (this.checked) {
$services.val($services.val() + this.value);
} else {
$services.val($services.val().replace(this.value, ""));
}
});

Your code will fire if you add ID's to your inputs:
<input type="checkbox" name="selectServices" id="selectServices" value="" />
and
<input name="services" id="services" type="text" />

angularjs dynamic radio button

The radio button are dynamically created.
the task i want is to have the first radio button selected by default and if i choose other option it should change and get selected, until that, first is the selected option.
tried this and many other codes by browsing. unable to find a perfect solution.
$scope.radioLoad = function() {
$scope.frmData.prpkval = 0;
$("input[name=primarypackage][value=" + $scope.frmData.prpkval + "]").prop('checked', true);
}
<input name="primarypackage" class="radioBtn" type="radio" init="radioLoad()" ng-value="{{frmData.prpkval}}" ng-model="$parent.primarypackage">

Please find the code here.
HTML:
<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>
<div ng-app="app" ng-controller="test">
<span class="dymanic"></span>
</div>
JS:
var app = angular.module('app', []);
app.controller('test', function ($scope) {
$scope.createDynamicRadioButton = function () {
$('.dymanic').append(
'<div><label>Radio 1<input type="radio" name="radioButton"/></label></div>' + '<div><label>Radio 2<input type="radio" name="radioButton" /></label></div>' + '<div><label>Radio 3<input type="radio" name="radioButton" /></label></div>');
}
$scope.createDynamicRadioButton(); // generates radio button dynamically
$('input[name="radioButton"]').eq(0).prop('checked', true); //Checks the first radio button.
});

How to set default value checked in a checkbox from database using AngularJS

While editing the record the data comes in their respective fields for editing, but the checkbox is not checked if its value is 1.
It should be in checked state if it has 1 and not checked if it has 0 as the datatype of the field is tinyint. I am retrieving the data from JSON array via PHP. I am trying to get value by ng-checked="{{rec.isSpecial}}" but it is not working.
Here is my HTML:
<div class="form-group">
<div class="col-lg-offset-2 col-lg-10">
<div class="checkbox c-checkbox">
<label>
<input type="checkbox" ng-checked="{{rec.isSpecial}}" ng-model="rec.isSpecial">
<span class="fa fa-check"></span>Special
</label>
</div>
</div>
</div>
here is my JS
$scope.rec = $resource('api/AdminArea/category/edit/:id', {
id: id
}).get(function(data) {
$scope.rec = data;
});

Since your data returns numbers and not true or false values you could do like so:
<div class="form-group">
<div class="col-lg-offset-2 col-lg-10">
<div class="checkbox c-checkbox">
<label>
<input type="checkbox" ng-checked="rec.isSpecial==1" ng-model="rec.isSpecial">
<span class="fa fa-check"></span>Special
</label>
</div>
</div>
</div>
see fiddle for more info

You don't need ng-checked at all, ng-model is enough for it to work. If your rec.isSpecial is set to 1 for it to be checked then just your input like this:
<input type="checkbox" ng-model="rec.isSpecial" ng-value="1" />
and the Angular will automatically check that checkbox.

The expression ng-checked={{ ... }} expects a true or false statement.
If you would set rec.isSpecial = true, in your Angular controller, your code should work!

'use strict';
var app = angular.module('MyApp',[]);
app.controller('myController', function ($scope) {
$scope.isSpecial =true;
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="form-group" ng-app ="MyApp" ng-controller="myController">
<div class="col-lg-offset-2 col-lg-10">
<div class="checkbox c-checkbox">
<label>
<input type="checkbox" ng-checked="{{isSpecial}}" ng-model="isSpecial">
<span class="fa fa-check"></span>Special
</label>
</div>
</div>
</div>

You don't really need the directive ng-checked if you are using ng-model in the tag input.
Since it is a checkbox, the model will be a boolean, so you need to make a cast. This example will work
HTML
<div data-ng-app="app">
<div data-ng-controller="MainController">
Check
<input type="checkbox" data-ng-model="isSpecial">
</div>
</div>
JS
angular.module('app', []);
angular.module('app')
.controller('MainController', mainController);
mainController.$inject = ['$scope'];
function mainController($scope){
$scope.check = 0;
$scope.isSpecial = ($scope.check === 1) ? true : false;
}

Angular checkboxes disapear on select

I have a list of checkboxes in my app:
<div class="col-md-6" ng-repeat="item in segment.items">
<div class="checkbox">
<label>
<input
type="checkbox"
ng-model="item"
ng-checked="item.enabled"
value="{{item.id}}"
class="segment-visibility-checkbox"
/>
{{item.name}} <code>/ {{item.slug}}</code>
</label>
</div>
</div>
The data, that exists on the $scope as segment.items, looks something like this:
[
{"id":1,"slug":"nl","name":"Dutch","enabled":true},
{"id":4,"slug":"en","name":"English","enabled":false},
{"id":2,"slug":"fr","name":"French","enabled":true},
{"id":3,"slug":"de","name":"German","enabled":false}
]
This renders fine on load, and the correct checboxes are checked. However, if I select a checkbox, the label disappears and the binding appears to be lost. If I deselect a checkbox, it seems to work fine, but if I select it again, it disappears as well. No errors show up in the console.
This is what it looks like on load:
And as soon as I click on "English" I get this
I'm new to Angular so I suspect I am doing something obvious wrong. Can anybody please point me in the right direction?

pointing your ng-model to ng-model="item" will cast your item into a boolean.
Also, you should not use ng-model with ng-checked : https://docs.angularjs.org/api/ng/directive/ngChecked
what you should do is the following :
<input
type="checkbox"
ng-model="item.enabled"
value="{{item.id}}"
class="segment-visibility-checkbox"
/>

You need to bind the ng-model directly on your enabled boolean attribute:
<input
type="checkbox"
ng-model="item.enabled"
value="{{item.id}}"
class="segment-visibility-checkbox"
/>
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function($scope) {
$scope.segment = {
items: [
{"id":1,"slug":"nl","name":"Dutch","enabled":true},
{"id":4,"slug":"en","name":"English","enabled":false},
{"id":2,"slug":"fr","name":"French","enabled":true},
{"id":3,"slug":"de","name":"German","enabled":false}
]
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
{{segment.items}}
<div class="col-md-6" ng-repeat="item in segment.items">
<div class="checkbox">
<label>
<input
type="checkbox"
ng-model="item.enabled"
value="{{item.id}}"
class="segment-visibility-checkbox"
/>
{{item.name}} <code>/ {{item.slug}}</code>
</label>
</div>
</div>
</div>

Angular: radiobuttons stop firing "ng-change" after each one was clicked

I am building radio buttons dynamically. ng-change='newValue(value) stops being called after each radio button has been pressed once.
this works: Clicking on the radio buttons changes the value to foo/bar/baz.
http://jsfiddle.net/ZPcSe/19/
<div ng-controller="MyCtrl">
<input type="radio" ng-model="value" value="foo" ng-change='newValue(value)'>
<input type="radio" ng-model="value" value="bar" ng-change='newValue(value)'>
<input type="radio" ng-model="value" value="baz" ng-change='newValue(value)'>
<hr>
{{value}}
</div>
this code does not: The {{value}} - "label" is not updated once each radio button has been pressed at least once. Aparently ng-change is not fired any more.
<div ng-controller="MyCtrl">
<span ng-repeat="i in [0, 1, 2]">
<input name="asdf" type="radio" ng-model="value" value={{i}} ng-change='newValue(value)'>
</span>
{{value}}
</div>
http://jsfiddle.net/ZPcSe/18/
The Controlles is the same each time:
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.value = '-';
$scope.newValue = function(value) {
$scope.value = value;
}
}
Thanks for your help.

ngRepeat creates new scope, so trying to set value sets it on the new scope. The workaround is to reference a property on an object that is on the parent scope--the object lookup happens on the parent scope, and then changing the property works as expected:
HTML:
<div ng-controller="MyCtrl">
<span ng-repeat="i in [0, 1, 2]">
<input name="asdf" ng-model="options.value" value="{{i}}" type="radio">
</span>
{{options.value}}
JS:
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.options = {
value: '-'
};
$scope.newValue = function(value) {
// $scope.options.value = value; // not needed, unless you want to do more work on a change
}
}​
You can check out a working fiddle of this workaround. See angular/angular.js#1100 on GitHub for more information.

Just a quick work-around, we can achieve the same- using ng-model="$parent.value", because it would refer to the parent of ng-repeat scope i.e- in myCtrl scope
Only Change in ng-model-
<input name="asdf" type="radio" ng-model="$parent.value" value={{i}} ng-change='newValue(value)'>
Here is the fiddle

Try ng-click instead of ng-change.
