Angular checkbox and ng-click
AngularjsAngularjs Problem Overview
Angular 1.2:
<input type="checkbox" ng-model="vm.myChkModel" ng-click="vm.myClick(vm.myChkModel)">
I don't have the right state in my myClick function?
I want the state, after the click.
Angularjs Solutions
Solution 1 - Angularjs
The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.
In your case, this should work:
<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
Solution 2 - Angularjs
You can use ng-change instead of ng-click:
<!doctype html>
<html>
<head>
<script src="http://code.angularjs.org/1.2.3/angular.min.js"></script>
<script>
var app = angular.module('myapp', []);
app.controller('mainController', function($scope) {
$scope.vm = {};
$scope.vm.myClick = function($event) {
alert($event);
}
});
</script>
</head>
<body ng-app="myapp">
<div ng-controller="mainController">
<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
</div>
</body>
</html>
Solution 3 - Angularjs
cardeal's answer was really helpful. Took it a little further and figured it may help others some where down the line. Here is the fiddle:

And the code:
<body ng-app="checkboxExample">
<script>
angular.module('checkboxExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.value0 = "none";
$scope.value1 = "none";
$scope.value2 = "none";
$scope.value3 = "none";
$scope.checkboxModel = {
critical1: {selected: true, id: 'C1', error:'critical' , score:20},
critical2: {selected: false, id: 'C2', error:'critical' , score:30},
critical3: {selected: false, id: 'C3', error:'critical' , score:40},
myClick : function($event) {
$scope.value0 = $event.selected;
$scope.value1 = $event.id;
$scope.value2 = $event.error;
$scope.value3 = $event.score;
}
};
}]);
</script>
<form name="myForm" ng-controller="ExampleController">
<label>
Value1:
<input type="checkbox" ng-model="checkboxModel.critical1.selected" ng-change="checkboxModel.myClick(checkboxModel.critical1)">
</label><br/>
<label>Value2:
<input type="checkbox" ng-model="checkboxModel.critical2.selected" ng-change="checkboxModel.myClick(checkboxModel.critical2)">
</label><br/>
<label>Value3:
<input type="checkbox" ng-model="checkboxModel.critical3.selected" ng-change="checkboxModel.myClick(checkboxModel.critical3)">
</label><br/><br/><br/><br/>
<tt>selected = {{value0}}</tt><br/>
<tt>id = {{value1}}</tt><br/>
<tt>error = {{value2}}</tt><br/>
<tt>score = {{value3}}</tt><br/>
</form>
Solution 4 - Angularjs
The order of execution of ng-click and ng-model is different with angular 1.2 vs 1.6
You must test, with 1.2 and 1.6,
for example, with angular 1.2, ng-click get execute before ng-model, with angular 1.6, ng-model maybe get excute before ng-click.
so you get 'true checked' / 'false uncheck' value maybe not you expect
