select all checkboxes with angular JS

问题

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;
        });
    };

You are missed the container divs with ng-controller and ng-app and angular.module.

user.select = $scope.selectAll is the correct variant.

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;
    });
  }
});

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>

Simple use the following code

HTML

<input type="checkbox" ng-model="checkboxes.checked" data-ng-click="checkAll()" class="select-all" value="" />

  $scope.checkAll = function() {
                angular.forEach($scope.users, function(item) {
                $scope.checkboxes.items[item._id] =      $scope.checkboxes.checked;
                $scope.selection.push(item._id);
            });
               }
