I've got an angularjs application that has a form/controller that look essentially like this (boiled down to the pertinent stuff):
angular.module('testApp', [])
.controller('testCtrl', function ($scope) {
$scope.envelopes = [{
id: 1,
name: 'first',
default_spend: '1'
}, {
id: 2,
name: 'second',
default_spend: '0'
}, {
id: 3,
name: 'third',
default_spend: '0'
}, ];
});
And a form that looks roughly like this:
<div ng-app="testApp">
<div ng-controller="testCtrl">
<div ng-repeat="envelope in envelopes">
<div>{{envelope.name}}
<input type="radio" name="default_spend" ng-model="envelope.default_spend" ng-value="1" />
Default Spend: {{envelope.default_spend}}
</div>
</div>
</div>
</div>
You can see this in action with this fiddle.
As you can see, the first envelope is marked as the default_spend envelope and the other two aren't. When I select a different envelope, that envelope also gets marked as the default_spend, but when the radio button is unselected, the model value stays the same ("1"). I understand that I'm dealing with a child scope here due to ng-repeat, but is there a way for me to set an "unselected" value without having to jump through hoops with ngChange?
Not really. When you use ng-value it is what is going to get bound to the ng-model and in your case all of them are having value 1. Also i really did not get the purpose of toggling 1 and 0, however you could just achieve it this way:-
<input type="radio" name="default_spend"
ng-click="selected.envelope = envelope" /> <!--Register an ng-click and set selected one
Default Spend: {{getDefSpend(envelope)}}</div> <!-- Show the text based on selection-->
And in your controller:-
$scope.selected = {envelope: $scope.envelopes[0]};
$scope.getDefSpend = function(envelope){
return $scope.selected.envelope === envelope ? 1 : 0;
}
//$scope.selected.envelope will be your selected option at any point.
Demo
It's because what you have is actually 3 different model values. To work as you want it, you would have ONE model value for all 3. You can either restructure your data, or use ng-change to modify your model manually.

Here I am binding values to ng-click as
<input type="checkbox" ng-model="a.CheckAssign"ng-click="myFunctionnew(a.ENQUIRY_CODE,a.CheckAssign)" />
enquiryArr=[]
$scope.myFunctionnew = function(enqcode,checkassign)
{
enquiryArr.push(enqcode + '&' + checkassign)
var uniqueNames = [];
$.each(enquiryArr, function (i, el) {
if ($.inArray(el, uniqueNames) === -1) {
uniqueNames.push(el);
console.log(uniqueNames)
}
else
{
console.log(uniqueNames);
}
}
Here when I check and uncheck the checkbox the value is storing multiple
Please help me how can I store Enquiry code and T/F values.
If I understand your issue correctly, you're running into duplicate entries in your enquiryArr. You're running into this because you're trying to manually keep track of the array in an odd fashion. While there are ways to correct the way you're storing it, it's even easier to have angular track what is checked and what is not.
Using the following DataSet:
$scope.enquiries = [
{ENQUIRY_CODE: 'ENQUIRY_1', ENQUIRY_NAME: 'First Enquiry', selected: false},
{ENQUIRY_CODE: 'ENQUIRY_2', ENQUIRY_NAME: 'Second Enquiry', selected: false},
{ENQUIRY_CODE: 'ENQUIRY_3', ENQUIRY_NAME: 'Third Enquiry', selected: false},
{ENQUIRY_CODE: 'ENQUIRY_4', ENQUIRY_NAME: 'Fourth Enquiry', selected: false}
];
And binding the selected field to your checkboxes ng-model
<div ng-repeat="e in enquiries">
<input type="checkbox" ng-model="e.selected" />
{{e.ENQUIRY_NAME}}
</div>
You can determine which one is checked simply by looking at the $scope.enquiries array and looking for selected: true (or false if you want to know the ones not checked).
In javascript you can use a simple Array Filter to get the selected values as such:
$scope.enquiries.filter(e => e.selected);
Or if you want to get them in your template, you can also use the filter pipe as such:
{{(enquiries | filter:{selected:true})}}
Here is an interactive plunkr that you can view this.
Misc Note: If you do want to run something when the checkbox is clicked, you can still use an ng-click and run your custom code, however, I would recommend using ng-change as there are other ways to change the selected value of a checkbox other than clicking.
I have test your code and its working fine. your problem is not so much clear so you can check following test code.
<div ng-controller="MyController">
<div ng-repeat="dt in data">
<input type="checkbox" ng-model="CheckAssign" ng-click="myFunctionnew(dt.name,dt.volume)" />
</div>
</div>
Javascript
$scope.myFunctionnew = function(enqcode,checkassign)
{
enquiryArr.push(enqcode + '&' + checkassign)
var uniqueNames = [];
for(i=0; i <enquiryArr.length; i++) {
if ($.inArray(enquiryArr[i], uniqueNames) == -1) {
uniqueNames.push(enquiryArr[i]);
console.log(uniqueNames)
}
else
{
console.log(uniqueNames);
}
}
}

I facing an issue with having multiple selects in angularJS where each one of them is linked to the previous one and the value depended on the previous item selected which looks like could be done easily by angular but I am having a hard time figuring out how do I make the index of one select be passed to another select and at the same time making it unresponsive until some value is selected.
I also created a fiddle for the same for people to fiddle around with it.
Here is the concerned HTML
<div ng-app="myApp">
<div ng-controller="testController">
<select ng-model="carBrand" name="carBrand" required ng-options=" brand for brand in brands"></select>
<select ng-model="carModel" name="carModel" required ng-options="model.name for model in cars[0]"></select>
<!--I want the car brand(cars[0]) to be dynamic here. It should be prefreberably blacked out or uneditable until a Car brand is selected and once that particular brand is selected all the models pertaining to that brand only should be displayed in the ajoining select button-->
</div>
</div>
and an example app.js. Find the complete one at the fiddle
var app = angular.module('myApp', []);
app.controller("testController", function($scope) {
$scope.brands = ['Ford', 'Honda', 'Hyundai', 'Mahindra',
'Maruti Suzuki', 'Nissan', 'Renault', 'Skoda', 'Tata', 'Toyota', 'Volksvagen'
];
$scope.carBrand = $scope.brands[0];
$scope.cars = [];
/*These cars[0] and cars[1] are static declared but could well be called from a REST API endpoint in angular. For simplicity lets say they are already present. */
$scope.cars[0] = $scope.cars[0] = [{
name: "Figo",
capacity: 45
}, {
name: "Ecosport",
capacity: 52
}, {
name: "Fiesta",
capacity: 45
}, {
name: "Endeavour",
capacity: 71
}];
});
How do I solve the issue of getting an index from one select and passing it to the other to make this work and probably an additional perk would be to make it unresponsive in case no brand is selected.
Try ng-change:
<select ng-model="carBrand" name="carBrand" required ng-options=" brand for brand in brands"
ng-change="selectedCar(carBrand)"></select>
This returns the index of the selected brand:
$scope.selectedCar = function(brand) {
$scope.carIndex = $scope.brands.indexOf(brand);
};
Use it with the other dropdown as:
<select ng-model="carModel" name="carModel" required
ng-options="model.name for model in cars[carIndex]"></select>
Working Fiddle
When you select something from the first select, carBrand goes from undefined to the selected brand. You thus want the second select to be disabled if the carBrand is undefined (falsy):
<select ng-disabled="!carBrand" ...>
Then, you need to second select to contain the models associated to the selected brand (which is carBrand). So you need something like
<select ng-options="model.name for model in getModelsOfBrand(carBrand)" ...>
Now just implement this getModelsOfBrand(carBrand) function in the scope. It would be much easier if you had a better object model, like for example:
$scope.brands = [
{
name: 'Ford',
models: [
{
name: 'Figo',
capacity: 45
},
...
]
},
...
];
Then it would be as easy as
<select ng-options="model.name for model in carBrand.models" ...>
I am trying to create a form using angularJs, I have some attributes which is of integer type.
for example, I have variable called admin_events, it has 3 values, 0, 1, 2 to indicate the user's right/permisson to access different files. The number 0 means no right, 1 means view only, 2 means full right.
Now I want to create a form for editing this attributes for the administrator.
How should I go about doing this?
I am thinking of using a angularJs to make 3 radio buttons/checkboxes of 1,2,and 3, so that the administrator can just click on the option and it will update the attributes.
Anyone has any suggestion on what is the best way to do this?
This is one possible approach. See inline comments for explaination.
app.controller('MainCtrl', function($scope, $filter) {
// set up your model
$scope.allPermissions = [
{ "id" : 3, "name" : "ADMIN", selected: false },
{ "id" : 2, "name" : "READ", selected: false },
{ "id" : 1, "name" : "WRITE", selected: false } ];
// Use $watch to detect changes in the model.
// But you might as well want to call this from an event or whatever...
$scope.$watch('allPermissions', function(newval, oldval){
if (oldval != newval)
{
// only return the checked values using $filter
var selectedPermission = $filter('filter')($scope.allPermissions, {selected: true});
// 'selectedPermission' will return a list of all selected permissions.
// Use 'selectedPermission[0].id' to return the first value.
$scope.admin_events = selectedPermission[0].id;
}
},true);
});
And in your HTML
<body ng-controller="MainCtrl">
<p ng-repeat="permission in allPermissions">
<input type="checkbox" ng-model="permission.selected"/>
{{permission.name}}
</p>
admin_events: {{admin_events}}
</body>
In the end, I decided to use a range type input to achieve the selection. It is much easier to implement.
<input ng-model= "user.activities.events" name="activities.events" type="range" max="2" min="0" class="form-control">
But i think #sjokkogutten's answer is not bad too. But the checkboxes are not mutally exclusive. Thanks anyway #sjokkogutten.
What I'm trying to do is have a service (lets say: myService) that holds specific data like objects representing printers present and selected:
var localPrinters = [{ id: 12, name: 'HP', type: 'laser' },
{ id: 33, name: 'Lexmark', type: 'laser' }];
var activePrinter = {};
In some view that gets shown occasionally (like app settings), I have a controller that would define variables in the local scope which would point to the objects in the injected myService.
The view would then use ng-repeat to iterate over printer objects in localPrinters and display radio buttons that correspond to each object in the array..
Now i need two things..
1) update the activePrinter upon radiobutton selection change with the corresponding object value
2) in case the activePrinter already contains an object, when the view loads i want the corresponding radio to be checked already (if its value object matches the object in activePrinter, otherwise none should be selected.
I've managed 1) in a couple of ways.. either sticking to the model usage or adding methods to call upon ng-change.
//pseudocode
<container ng-repeat="printer in printers" >
<radio ng-value="printer" ng-model="$scope.activePrinter"/>
</container>
or
//pseudocode
<container ng-repeat="printer in printers" >
<radio ng-value="printer" ng-change="selectPrinter(printer)" "ng-model="$scope.activePrinter"/>
</container>
What i'm having trouble with is 2)
Not sure if there's a way in angular to automatically figure out some of the printer values matches the activePrinter selection and make the radio checked. Also not sure of the way i'm using ng-model for this purpose.
Any pointers?
Thanks!
You can do that in this way:
var app = angular.module('app', []);
app.controller('firstCtrl', function($scope) {
$scope.printers = [{
id: 12,
name: 'HP',
type: 'laser'
}, {
id: 33,
name: 'Lexmark',
type: 'laser'
}];
$scope.activePrinter = {};
//set default printer
$scope.activePrinter.printer = $scope.printers[0]
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app">
<div ng-controller="firstCtrl">
<div class="container" ng-repeat="printer in printers">
<label>{{printer.name}}</label>
<input type="radio" ng-value="printer" ng-model="activePrinter.printer" />
</div>
Active Printer:{{activePrinter.printer.id}} | {{activePrinter.printer.name}} | {{activePrinter.printer.type}}
</div>
</body>
I have an ngRepeat that populates a list of customers, shown here :
<div ng-repeat="terr in terrData.data">
<div class="customer-row" ng-click="clickCustomerSelect(terr)">
<input class="customer-radio" type="radio" name="customer-select" ng-model="selectedCustomerRow" value="{{terr.customerID}}">
<div class="contact-data-column">{{terr.custNm}}</div>
<div class="primaryphone-data-column">{{terr.primaryPhone}}</div>
<!-- other customer data -->
</div>
</div>
There is a click event on the customer-row div that says if the row is clicked, the radio button for the row should be checked.
The basic controller logic shown here :
$scope.clickCustomerSelect = function(customer){
$scope.selectedCustomerRow = customer.customerID.toString();
//Other business logic
};
I see that whenever the customer row is clicked (not the radio button), the model gets properly updated, and the radio button corresponding to that value is checked. Note that this is expected functionality.
The issue i'm seeing is that if you check the radio button manually (i.e. not clicking the row), the model will no longer respond to updates from clicking the row.
I'm wondering if somehow once you select the radio button you're going outside of angular scope?
EDIT: Sample model
terrData.data = [{
"customerID": 1,
"companyName": "Name 1",
"custNm": "Blank",
"primaryPhone": "111-111-1111"
}, {
"customerID": 2,
"companyName": "Name 2",
"custNm": "Blank",
"primaryPhone": "111-111-1112"
}, {
"customerID": 3,
"companyName": "Name 3",
"primaryPhone": "111-111-1113"
}];
$scope.selectedCustomerRow = customer.customerID.toString();
Replace To:
$scope.selectedCustomerRow = customer.customerID;
onclick with it set selectedCustomerRow.
in HTML
<input class="customer-radio" type="radio" name="customer-select" ng-model="selectedCustomerRow" value="{{terr.customerID}}">
Replace To:
<input class="customer-radio" type="radio" name="customer-select" ng-model="$parent.selectedCustomerRow" value="{{terr.customerID}}">

Likely your problem is this: https://stackoverflow.com/a/17607794/170407
Short answer: ng-model almost always needs a dot in it.
