<!DOCTYPE html>

<body>
<input type="checkbox" ng-checked="user.roles.length == roles.length" ng-click="checkAll()" >全选/反选
<input type="checkbox" checklist-model="user.roles" checklist-value="role" > {{role.text}}
<br>
<br> user.roles {{ user.roles}}<br>
<br> role.id {{ids}}<br>
<button class="right radius reveal-button" ng-click="del()">删除</button>
</div>
</body>
</html>
var app = angular.module("app", ["checklist-model"]);
app.controller('Ctrl', function($scope) {
$scope.roles = [
{id: 1, text: 'guest'},
{id: 2, text: 'user'},
{id: 3, text: 'customer'},
{id: 4, text: 'admin'}
];
$scope.ids = [];
//选择的结果集合
$scope.user = {
roles: []
};
$scope.checkAll = function() {
console.log($scope.user.roles.length == $scope.roles.length)
if($scope.user.roles.length == $scope.roles.length){
$scope.user.roles = [];
$scope.ids = [];
}else{
$scope.user.roles = angular.copy($scope.roles);
$scope.ids = [];
}
};
$scope.del =function(){
for(x in $scope.user.roles){
$scope.ids.push($scope.user.roles[x].id);
}
console.log($scope.ids)
};
});
