<input type='checkbox' ng-repeat="fruit in fruits"
  ng-checked="checkedFruits.indexOf(fruit) != -1" ng-click="toggleCheck(fruit)">

.

function SomeCtrl ($scope) {
    $scope.fruits = ["apple, orange, pear, naartjie"];
    $scope.checkedFruits = [];
    $scope.toggleCheck = function (fruit) {
        if ($scope.checkedFruits.indexOf(fruit) === -1) {
            $scope.checkedFruits.push(fruit);
        } else {
            $scope.checkedFruits.splice($scope.checkedFruits.indexOf(fruit), 1);
        }
    };
}

  <div ng-app='app' >
    <div ng-controller='MainCtrl' >
       <ul> 
       <li ng-repeat="tab in data">
         <input type='checkbox' ng-click='change($index,confirm)' ng-model='confirm' />
         {{tab.name}} 
         </li>
     </ul>
    {{val}}
   </div>
 </div>


var app = angular.module('app', []);
 app.controller('MainCtrl',function($scope){
 $scope.val=[];
  $scope.confirm=false;
  $scope.data=[
   {
     name:'vijay'
     },
    {
      name:'krishna'
    },{
      name:'Nikhil'
     }
    ];
    $scope.temp;
   $scope.change=function(index,confirm){
     console.log(confirm);
    if(!confirm){
     ($scope.val).push($scope.data[index]);   
    }
    else{
    $scope.temp=$scope.data[index];
        var d=($scope.val).indexOf($scope.temp);
        if(d!=undefined){
         ($scope.val).splice(d,1);
        }    
       }
     }   
   })

使用$index字符串可以帮助使用选定值的hashmap:

<ul>
    <li ng-repeat="someItem in someArray">
        <input type="checkbox" ng-model="someObject[$index.toString()]" />
    </li>
</ul>

这样ng-model对象就用表示索引的键更新了。

$scope.someObject = {};

一段时间后$scope。someObject应该看起来像这样:

$scope.someObject = {
     0: true,
     4: false,
     1: true
};

这种方法并不适用于所有情况，但很容易实现。

我喜欢Yoshi的回答。我增强了它，所以你可以对多个列表使用相同的函数。

<label ng-repeat="fruitName in fruits">
<input
type="checkbox"
name="selectedFruits[]"
value="{{fruitName}}"
ng-checked="selection.indexOf(fruitName) > -1"
ng-click="toggleSelection(fruitName, selection)"> {{fruitName}}
</label>


<label ng-repeat="veggieName in veggies">
<input
type="checkbox"
name="selectedVeggies[]"
value="{{veggieName}}"
ng-checked="veggieSelection.indexOf(veggieName) > -1"
ng-click="toggleSelection(veggieName, veggieSelection)"> {{veggieName}}
</label>



app.controller('SimpleArrayCtrl', ['$scope', function SimpleArrayCtrl($scope) {
  // fruits
  $scope.fruits = ['apple', 'orange', 'pear', 'naartjie'];
  $scope.veggies = ['lettuce', 'cabbage', 'tomato']
  // selected fruits
  $scope.selection = ['apple', 'pear'];
  $scope.veggieSelection = ['lettuce']
  // toggle selection for a given fruit by name
  $scope.toggleSelection = function toggleSelection(selectionName, listSelection) {
    var idx = listSelection.indexOf(selectionName);

    // is currently selected
    if (idx > -1) {
      listSelection.splice(idx, 1);
    }

    // is newly selected
    else {
      listSelection.push(selectionName);
    }
  };
}]);

使用@Umur kontacabi这个例子，我认为在使用捕获选择的数据通过另一个对象/数组，像一个编辑页面。

捕获数据库中的选项

切换某个选项

例如，下面是所有颜色的json:

{
    "colors": [
        {
            "id": 1,
            "title": "Preto - #000000"
        },
        {
            "id": 2,
            "title": "Azul - #005AB1"
        },
        {
            "id": 3,
            "title": "Azul Marinho - #001A66"
        },
        {
            "id": 4,
            "title": "Amarelo - #FFF100"
        },
        {
            "id": 5,
            "title": "Vermelho - #E92717"
        },
        {
            "id": 6,
            "title": "Verde - #008D2F"
        },
        {
            "id": 7,
            "title": "Cinza - #8A8A8A"
        },
        {
            "id": 8,
            "title": "Prata - #C8C9CF"
        },
        {
            "id": 9,
            "title": "Rosa - #EF586B"
        },
        {
            "id": 10,
            "title": "Nude - #E4CAA6"
        },
        {
            "id": 11,
            "title": "Laranja - #F68700"
        },
        {
            "id": 12,
            "title": "Branco - #FFFFFF"
        },
        {
            "id": 13,
            "title": "Marrom - #764715"
        },
        {
            "id": 14,
            "title": "Dourado - #D9A300"
        },
        {
            "id": 15,
            "title": "Bordo - #57001B"
        },
        {
            "id": 16,
            "title": "Roxo - #3A0858"
        },
        {
            "id": 18,
            "title": "Estampado "
        },
        {
            "id": 17,
            "title": "Bege - #E5CC9D"
        }
    ]
}

以及2种类型的数据对象，包含一个对象的数组和包含两个/多个对象数据的对象:

在数据库中选择两个捕获项: [{" id ": 12,“标题”:“布兰科- # FFFFFF "}, {" id ": 16,“标题”:“Roxo - # 3 a0858”}] 在数据库中选择一个捕获项: {"id":12，"title":"Branco - #FFFFFF"}

这里是我的javascript代码:

/**
 * Add this code after catch data of database.
 */

vm.checkedColors = [];
var _colorObj = vm.formData.color_ids;
var _color_ids = [];

if (angular.isObject(_colorObj)) {
    // vm.checkedColors.push(_colorObj);
    _color_ids.push(_colorObj);
} else if (angular.isArray(_colorObj)) {
    angular.forEach(_colorObj, function (value, key) {
        // vm.checkedColors.push(key + ':' + value);
        _color_ids.push(key + ':' + value);
    });
}

angular.forEach(vm.productColors, function (object) {
    angular.forEach(_color_ids, function (color) {
        if (color.id === object.id) {
            vm.checkedColors.push(object);
        }
    });
});

/**
 * Add this code in your js function initialized in this HTML page
 */
vm.toggleColor = function (color) {
    console.log('toggleColor is: ', color);

    if (vm.checkedColors.indexOf(color) === -1) {
        vm.checkedColors.push(color);
    } else {
        vm.checkedColors.splice(vm.checkedColors.indexOf(color), 1);
    }
    vm.formData.color_ids = vm.checkedColors;
};

我的Html代码:

<div class="checkbox" ng-repeat="color in productColors">
    <label>
        <input type="checkbox"
               ng-checked="checkedColors.indexOf(color) != -1"
               ng-click="toggleColor(color)"/>
        <% color.title %>
    </label>
</div>

<p>checkedColors Output:</p>
<pre><% checkedColors %></pre>

[编辑]重构代码如下:

function makeCheckedOptions(objectOptions, optionObj) {
    var checkedOptions = [];
    var savedOptions = [];

    if (angular.isObject(optionObj)) {
        savedOptions.push(optionObj);
    } else if (angular.isArray(optionObj)) {
        angular.forEach(optionObj, function (value, key) {
            savedOptions.push(key + ':' + value);
        });
    }

    angular.forEach(objectOptions, function (object) {
        angular.forEach(savedOptions, function (color) {
            if (color.id === object.id) {
                checkedOptions.push(object);
            }
        });
    });

    return checkedOptions;
}

并调用new方法如下所示:

vm.checkedColors = makeCheckedOptions(productColors, vm.formData.color_ids);

就是这样!

如果在同一个表单上有多个复选框

控制器代码

vm.doYouHaveCheckBox = ['aaa', 'ccc', 'bbb'];
vm.desiredRoutesCheckBox = ['ddd', 'ccc', 'Default'];
vm.doYouHaveCBSelection = [];
vm.desiredRoutesCBSelection = [];

视图代码

<div ng-repeat="doYouHaveOption in vm.doYouHaveCheckBox">
    <div class="action-checkbox">
        <input id="{{doYouHaveOption}}" type="checkbox" value="{{doYouHaveOption}}" ng-checked="vm.doYouHaveCBSelection.indexOf(doYouHaveOption) > -1" ng-click="vm.toggleSelection(doYouHaveOption,vm.doYouHaveCBSelection)" />
        <label for="{{doYouHaveOption}}"></label>
        {{doYouHaveOption}}
    </div>
</div>

<div ng-repeat="desiredRoutesOption in vm.desiredRoutesCheckBox">
     <div class="action-checkbox">
          <input id="{{desiredRoutesOption}}" type="checkbox" value="{{desiredRoutesOption}}" ng-checked="vm.desiredRoutesCBSelection.indexOf(desiredRoutesOption) > -1" ng-click="vm.toggleSelection(desiredRoutesOption,vm.desiredRoutesCBSelection)" />
          <label for="{{desiredRoutesOption}}"></label>
          {{desiredRoutesOption}}
     </div>
</div>
