How to make checkboxes behave like radio buttons in ng-repeat?
Question
I have faced problem to use Checkbox behave like radio button in ng-repeat. Where select and unselect the box and one time only one box will be selected. It is working Without Ng-repeat. But i want to use this in ng-repeat.
Here is my HTML File :
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');</script>
<link rel="stylesheet" href="style.css" />
<script data-require="angular.js@1.1.x" src="http://code.angularjs.org/1.1.5/angular.min.js" data-semver="1.1.5"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<h1> WithOut ng-repeat </h1>
<input type="checkbox" ng-checked="model1=='11'" ng-click="model1='11'"> a
<br/>
<input type="checkbox" ng-checked="model1=='12'" ng-click="model1='12'"> b
<br/>
<input type="checkbox" ng-checked="model1=='13'" ng-click="model1='13'"> c
<br>
Model = {{model1}}
<h1> With ng-repeat </h1>
<div data-ng-repeat="p in pp.rate">
<input type="checkbox" ng-checked="model=='{{p.price}}'"
ng-click="model='{{p.price}}'">
Model = {{model}}
</div>
</body>
</html>
Here is My Controller :
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.pp = {
rate: [ {price: '11'},
{price: '12'},
{price: '13'}
]
};
});

I had the same problem today and I finally found a nice solution:
<div data-ng-repeat="p in pp.rate">
<input type="checkbox" ng-model="result.price" ng-true-value="{{p.price}}" ng-false-value="" >
{{p.plan}}
</div>

The issue is with ng-repeat creating a new scope and you not using dot notation to reference your model.
See the updated plunkr here http://plnkr.co/edit/EQdv60ppdVm5Nkp2o8p8?p=preview
I added a object selection that tracks selection instead of a model string value. The checkbox is then checked against selection.model instead of model
Highly recommend you read https://github.com/angular/angular.js/wiki/Understanding-Scopes to understand prototypal inheritance and the effect on scope.
