I create quiz app with angularjs and have some issues.
When I click "next" checked radio doesn`t reset
<div ng-repeat="answ in quiz.typical">
<label ng-click="quiz.checkAnsw()">
<input type="radio" name="answ{{quiz.qNum}}">
{{answ.text}}
</label>
</div>
Fiddle
How reset checked radio?
You could set values to the radio then bind them to a property via ng-model:
<div ng-repeat="answ in quiz.typical">
<label ng-click="quiz.checkAnsw()">
<input type="radio" name="answ{{quiz.qNum}}" ng-value="$index" ng-model="quiz.selectedAns" />
{{answ.text}}
</label>
</div>
and in the controller, reset the quiz.selectedAns to undefined:
this.changeQ = function(){
this.qNum++;
this.selectedAns = undefined;
};

I am working on an AngularJS application. I am trying to create a page that allows the user to select one of three radio buttons. Two of the three also have checkboxes underneath them to allow the user to select additional options if they've selected the appropriate radio button. To try to prevent improper checkbox selections, I'm trying to set the ng-disabled attribute on the checkboxes. So far, it's not working, and I've tried several different iterations.
This is my HTML:
<div class="panel-body">
<input type="radio" id="notFraudulent" name="actionSelector" ng-model="cleared" /><label for="notFraudulentRadio"> Not Fraudulent</label><br />
<input type="checkbox" id="highVolumeCustomer" ng-model="highVolumeCustomer" ng-disabled="(fraudulent||cleared)" /><label for="highVolumeCustomer"> High Volume Customer</label><br />
<br/>
<input type="radio" id="appearsFraudulent" name="actionSelector" ng-model="fraudulent" /><label for="isFraudulentRadio"> Appears Fraudulent</label><br />
<input type="checkbox" id="reportAccount" ng-model="reportAccount" ng-disabled="(cleared||reviewed)" /><label for="reportAccount"> Report Account</label><br />
<br/>
<input type="radio" id="markReviewed" name="actionSelector" ng-model="reviewed" /><label for="markReviewed"> Mark As Reviewed For Later</label>
</div>
I have tried changing the operator on the ng-disabled expressions to &&, as I've seen some articles where it's suggested that the operators don't mean what one thinks they mean. But that doesn't work, and neither does it work if I put just a single condition in the expression. There isn't anything in the controller (yet) that tries to use or manipulate any of the ng-models in the HTML. I've come to the conclusion that there's something I'm missing with regard to the radio buttons, but I can't for the life of me figure out what.
Can anyone see what my mistake is?
you should use value property to bind special value for radio button, and when radiobutton's status is changed, the value will be kept at ng-model.
refer the code snippet below:
angular.module("app", [])
.controller("myCtrl", function($scope) {
$scope.selectedValue = 'cleared';
$scope.cleared = false;
$scope.fraudulent = false;
$scope.reviewed = false;
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="panel-body" ng-app='app' ng-controller="myCtrl">
<input type="radio" id="notFraudulentRadio" name="actionSelector" value="cleared" ng-model="selectedValue" /><label for="notFraudulentRadio"> Not Fraudulent</label><br />
<input type="checkbox" id="highVolumeCustomer" ng-model="highVolumeCustomer" ng-disabled="selectedValue === 'fraudulent' || selectedValue === 'cleared'" /><label for="highVolumeCustomer"> High Volume Customer</label><br />
<br/>
<input type="radio" id="isFraudulentRadio" name="actionSelector" value="fraudulent" ng-model="selectedValue"/><label for="isFraudulentRadio"> Appears Fraudulent</label><br />
<input type="checkbox" id="reportAccount" ng-model="reportAccount" ng-disabled="selectedValue === 'cleared' || selectedValue === 'reviewed'" /><label for="reportAccount"> Report Account</label><br />
<br/>
<input type="radio" id="markReviewed" name="actionSelector" value="reviewed" ng-model="selectedValue"/><label for="markReviewed"> Mark As Reviewed For Later</label>
<br>
cleared:{{cleared}}<br>
fraudulent:{{fraudulent}}<br>
reviewed:{{reviewed}}<br>
selectedValue: {{selectedValue}}
</div>
So, I have two toggle buttons, the user must be able only to select one of the above two toggle buttons as show in the image below:
How can I achieve this ?
You can use Radio buttons : http://ionicframework.com/docs/v1/components/#radio-buttons
But if you want to use toggle button and achieve this thing, you can use $watch : Documentation
Ionic code:
<label class="toggle">Bride only
<input type="checkbox" ng-model="B">
<div class="track">
<div class="handle"></div>
</div>
</label>
<br>
<label class="toggle">Bride & Bridesmaids
<input type="checkbox" ng-model="B&B">
<div class="track">
<div class="handle"></div>
</div>
</label>
Angular code:
$scope.B=false; // for Bride only
$scope.B&b= false //for Bride and Bridesmaids
$scope.$watch('B',function(){
if($scope.B==true){
$scope.B&B=false;
console.log($scope.B&B);
}
});
$scope.$watch('B&B',function(){
if($scope.B&B==true){
$scope.B=false;
console.log($scope.B);
}
});
Hope this helps.
I have checkbox group:
<div class="checkbox">
<input type="checkbox" name="zainteresowany1" ng-model="zainteresowany1">Stażem
</div>
<div class="checkbox">
<input type="checkbox" name="zainteresowany2" ng-model="zainteresowany2">Pracą
</div>
And I would like to validate form if nothing checkbox is selected.
If nothing is selected: form is invaild.
How to make?
Make the ng-model attribute the same for both checkboxes and set the value attribute for what value you want each to have when that checkbox is selected. Then you can validate the form by making sure the variable you use for ng-model is not undefined.
Example:
<div class="checkbox">
<input type="checkbox" name="zainteresowany1" ng-model="zainteresowany" value="foo" /> Stażem
</div>
<div class="checkbox">
<input type="checkbox" name="zainteresowany2" ng-model="zainteresowany" value="bar" /> Pracą
</div>
Then in your controller:
if (!$scope.zainteresowany) {
// Form is invalid
} else {
// Form is valid
var value = $scope.zainteresowany;
}
Anyone have other solution ? '
I want to validate form and IF ANY CHECKBOX is selected i want to make form $inval
I have a rails application which use AngularJS and I have a problem with a form, the problem is that I want to use a checkbox to send values true or false, but it only send true if it's checked and false if it's checked and unchecked after that, but if the user doesn't touch the checkbox, then it's not even sent as parameter.
<div class="checkbox">
<label>
<input type="checkbox" ng-model="car"> Do you have a car?
</label>
</div>
What can I do to make it send false if it the user doesn't ever check it?
Edit: The entire form is this, BTW, the form it's about creating a Poll, the car thing was just an example...
<h1>Create Poll</h1>
<form ng-submit="addPoll()" style="margin-top:30px;">
<div class="form-group">
<label>Title</label>
<input type="text" class="form-control" ng-model="title"></input>
</div>
<div class="form-group">
<label>Description</label>
<textarea type="text" class="form-control" ng-model="description"></textarea>
</div>
<br>
<div class="checkbox">
<label>
<input type="checkbox" ng-model="allow_anonymous_answer" ng-false-value="false"> Allow anonymous answers
</label>
</div>
<br>
<div class="form-group">
<label>Welcome message</label>
<textarea type="text" class="form-control" ng-model="initial_message"></textarea>
</div>
<div class="form-group">
<label>Outgoing Message</label>
<textarea type="text" class="form-control" ng-model="final_message"></textarea>
</div>
<button type="submit" class="btn btn-primary" style="float: right;">Continue</button>
</form>
When you hit Continue I make HTTP POST request with Restangular to create a Poll, but the problem is that when I don't touch the checkbox this is what I see in the log of Rails...
Started POST "/polls.json" for 127.0.0.1 at 2016-01-26 14:05:57 -0300
Processing by PollsController#create as JSON
Parameters: {"title"=>"asddddddddddddddda", "description"=>"aaaaaaaaaaaaaaaaaaaaa", "initial_message"=>"asdasdddddddddd", "final_message"=>"aaaaaaaaaaaaaaaaaaad", "poll"=>{"title"=>"asddddddddddddddda", "description"=>"aaaaaaaaaaaaaaaaaaaaa", "initial_message"=>"asdasdddddddddd", "final_message"=>"aaaaaaaaaaaaaaaaaaad"}}
Note that the parameter allow_anonymous_answer doesn't even appear, if I check the checkbox then I can see that the parameter is set as true, if I check it and then uncheck it, then it's set as false, but the problem is when the user doesn't even touch this, when this happens then the parameter is not even shown...
Just in case you wanna see, this is the controller of AngularJS...
angular.module('myapp').controller('CreatePollCtrl', ['$scope', 'Restangular',
function($scope, Restangular) {
Restangular.setFullResponse(true);
$scope.addPoll = function() {
var poll = {title: $scope.title, description: $scope.description, allow_anonymous_answer: $scope.allow_anonymous_answer, initial_message: $scope.initial_message, final_message: $scope.final_message};
Restangular.all('polls').post(poll).then(function(response) {
});
};
}]);
I think you should put a variable in your controller to achieve the binding between your HTML component and your JS code.
I am currently developing an Angular app, and what i do is to initialize all the ng-model variables in the first lines of my controller, so why dont you give a try to this:
In your first controllers lines:
$scope.allow_anonymous_answer = false;
Did you take a look at angular docs: https://docs.angularjs.org/api/ng/input/input[checkbox]
You can explicitly state what value the checkbox should send when it is not selected using ng-false-value
Add an ng-click to that checkbox and update the model there. Works fine.
<div class="checkbox">
<label>
<input type="checkbox" ng-model="car" ng-click="updateCar(this)">Do you have a car?</input>
</label>
</div>
In your controller:
var updateCar = function(checkbox) {
if (checkbox.checked) {
car = false;
}
else {
car = true;
}
}
I solved it...
In the controller
if ($scope.allow_anonymous_answer == null)
$scope.allow_anonymous_answer = false
I am having hard time figuring out how to work with radio buttons in Angular. Here is my fiddle:
http://jsfiddle.net/3bp2t4ma/
<div class="form-row full-width pull-left text-center check-as">
<label> <input name="ticket" type="radio"
ng-model="ticketType.type" ng-value="query"> Query
</label> <label class="complaint-check"> <input name="ticket"
type="radio" ng-model="tickeType.type" ng-value="complaint">
Complaint
</label>
</div>
{{ ticketType | json }}
And javascript:
var myApp = angular.module('myApp', []);
function Main($scope) {
$scope.ticketType={type: 'query'};
}
Any idea why ticketType becomes empty when I click on radio button?
Well, there is one obvious typo in the Complaint button: ng-model="tickeType.type"
You're missing a t.
