select all checkboxes with angular JS - html

Question

I am trying to select all checkboxes with one single checkbox. But how to do that?
This is my HTML:
<input type="checkbox" ng-model="selectAll" ng-click="checkAll()" />
<!-- userlist -->
<!--<div id="scrollArea" ng-controller="ScrollController">-->
<table class="table">
<tr>
<th>User ID</th>
<th>User Name</th>
<th>Select</th>
</tr>
<tr ng-repeat="user in users | filter:search">
<td>{{user.id}}</td>
<td>{{user.name}}</td>
<td><input type="checkbox" ng-click="usersetting(user)" ng-model="user.select"></td>
<td><tt>{{user.select}}</tt><br/></td>
</tr>
</table>
I create an extra checkbox to selecet and unselect all checkboxes.
JS:
.controller('UsersCtrl', function($scope, $http){
$http.get('users.json').then(function(usersResponse) {
$scope.users = usersResponse.data;
});
$scope.checkAll = function () {
angular.forEach($scope.users, function (user) {
user.select = true;
});
};
});
I tried this too, but none of them works for me :(
$scope.checkAll = function () {
angular.forEach($scope.users, function (user) {
user.select = $scope.selectAll;
});
};

Answer 1

You are missed the container divs with ng-controller and ng-app and angular.module.
user.select = $scope.selectAll is the correct variant.

Answer 2

Try setting the checked boxes against each user to be checked when the top checkbox is checked:
<input type="checkbox" ng-model="selectAll"/>
<table class="table">
<tr>
<th>User ID</th>
<th>User Name</th>
<th>Select</th>
</tr>
<tr ng-repeat="user in users | filter:search">
<td>{{user.id}}</td>
<td>{{user.name}}</td>
<td><input type="checkbox" ng-click="usersetting(user)" ng-model="user.select" ng-checked="selectAll"></td>
<td><tt>{{user.select}}</tt><br/></td>
</tr>
</table>

Here is a JSFiddle you can use ng-checked with a variable on it like user.checked (or use the user.select as you want)
<div ng-app="app" ng-controller="dummy">
<table>
<tr ng-repeat="user in users">
<td>{{user.id}}</td>
<td>{{user.name}}</td>
<td>
<input type="checkbox" ng-click="usersetting(user)" ng-checked="user.checked" ng-model="user.select">
</td>
<td><tt>{{user.select}}</tt>
<br/>
</td>
</tr>
</table>
<button ng-click="checkAll()">Check all</button>
</div>
JS:
var app = angular.module("app", []);
app.controller('dummy', function($scope) {
$scope.users = [{
id: 1,
name: "Hello",
select: 1
}, {
id: 2,
name: "World",
select: 1
}, ];
$scope.checkAll = function() {
angular.forEach($scope.users, function(user) {
user.checked = 1;
});
}
});

Simple use the following code
HTML
<input type="checkbox" ng-model="checkboxes.checked" data-ng-click="checkAll()" class="select-all" value="" />
JS
$scope.checkAll = function() {
angular.forEach($scope.users, function(item) {
$scope.checkboxes.items[item._id] = $scope.checkboxes.checked;
$scope.selection.push(item._id);
});
}
