我有一些复选框:

<input type='checkbox' value="apple" checked>
<input type='checkbox' value="orange">
<input type='checkbox' value="pear" checked>
<input type='checkbox' value="naartjie">

我想绑定到我的控制器中的一个列表,这样每当一个复选框被更改时,控制器就会维护一个包含所有选中值的列表,例如,['apple', 'pear']。

Ng-model似乎只能将一个复选框的值绑定到控制器中的一个变量。

是否有其他方法可以将这四个复选框绑定到控制器中的列表?


当前回答

<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);
        }
    };
}

看看这个有效管理复选框列表的指令。我希望这对你有用。 检查表模型

试试我的宝贝:

**

myApp.filter('inputSelected', function(){
  return function(formData){
    var keyArr = [];
    var word = [];
    Object.keys(formData).forEach(function(key){
    if (formData[key]){
        var keyCap = key.charAt(0).toUpperCase() + key.slice(1);
      for (var char = 0; char<keyCap.length; char++ ) {
        if (keyCap[char] == keyCap[char].toUpperCase()){
          var spacedLetter = ' '+ keyCap[char];
          word.push(spacedLetter);
        }
        else {
          word.push(keyCap[char]);
        }
      }
    }
    keyArr.push(word.join(''))
    word = [];
    })
    return keyArr.toString();
  }
})

**

然后对于任何带有复选框的ng-model,它将返回你选择的所有输入的字符串:

<label for="Heard about ITN">How did you hear about ITN?: *</label><br>
<label class="checkbox-inline"><input ng-model="formData.heardAboutItn.brotherOrSister" type="checkbox" >Brother or Sister</label>
<label class="checkbox-inline"><input ng-model="formData.heardAboutItn.friendOrAcquaintance" type="checkbox" >Friend or Acquaintance</label>


{{formData.heardAboutItn | inputSelected }}

//returns Brother or Sister, Friend or Acquaintance

在HTML中(假设复选框位于表中每一行的第一列)。

<tr ng-repeat="item in fruits">
    <td><input type="checkbox" ng-model="item.checked" ng-click="getChecked(item)"></td>
    <td ng-bind="fruit.name"></td>
    <td ng-bind="fruit.color"></td>
    ...
</tr>

在controllers.js文件:

// The data initialization part...
$scope.fruits = [
    {
      name: ....,
      color:....
    },
    {
      name: ....,
      color:....
    }
     ...
    ];

// The checked or not data is stored in the object array elements themselves
$scope.fruits.forEach(function(item){
    item.checked = false;
});

// The array to store checked fruit items
$scope.checkedItems = [];

// Every click on any checkbox will trigger the filter to find checked items
$scope.getChecked = function(item){
    $scope.checkedItems = $filter("filter")($scope.fruits,{checked:true});
};

我认为下面的方法对于嵌套ng-repeat更加清晰和有用。看看普伦克。

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);
    }
  };
}]);
