AngularJs. Is it possible to deselect HTML “radio” input by click?

Question

I have radio inputs and want to ucheck state by click on radio if current radio is checked.

This code:

<input type="radio" id="average_0" name="average" ng-model="checked" ng-change="false" value="500" class="ng-valid ng-dirty">
<input type="radio" id="average_1" name="average" ng-model="checked" ng-change="false" value="1000" class="ng-valid ng-dirty">
<input type="radio" id="average_2" name="average" ng-model="checked" ng-change="false" value="1500" class="ng-valid ng-dirty">

Not working.

Answer 1

Radio buttons can be selected only one at a time and cannot be unchecked by the user once they are checked (unless you do programmatically). So if you want to uncheck it when it is currently selected, you can do this:

<input type="radio" ng-model="checked" value="500" ng-click="uncheck($event)" />
<input type="radio" ng-model="checked" value="1000" ng-click="uncheck($event)" />
<input type="radio" ng-model="checked" value="1500" ng-click="uncheck($event)" />

In your controller:

$scope.uncheck = function (event) {
    if ($scope.checked == event.target.value)
        $scope.checked = false
}

NOTE: If you really want to choose one or none from many options, you may opt for a <select>

Don't you mean radio buttons in the answers first sentence? – Baskerville

This does not work in Angular 1.3 anymore. In 1.3, the checked value is set to "xyz" before the click event is fired. – Formica

how to uncheck radio buttons programatically without jQuery (and without direct user interaction)? – Shaunna

Answer 2

A simple solution that works on Angular 1.3+ is:

Template

<input type="radio" ng-model="forms.selected" value="{{value}}" ng-click="radioCheckUncheck($event)">

Controller

  let lastChecked = null
  $scope.radioCheckUncheck = function (event) {
    if (event.target.value === lastChecked) {
      delete $scope.forms.selected
      lastChecked = null
    } else {
      lastChecked = event.target.value
    }
  }

It's similar to the above solution, but maintains its own copy of the previous selection.

I solved the issue with the following code:

ng-dblclick = "{{model}} = '' "

You could do using below. set an attribute.

public selectedMoiProfile : boolean  = false;

<input type="radio" 
       name="selectMoi"
       [checked]="selectedProfile"
       [value]="selectedProfile"
       (click)="onSelect(moiProfile)"
       class="selectMoi">


 onSelect(p: profile) {
     p.selectedProfile= p.selectedProfile? false : true;
 }
