我有一个给定的对象数组,我想根据相关的复选框将其对象添加到“选定”列表中。如何在不必将控制器设置得太多的情况下进行设置。
当使用收音机时,这是小提琴,它很好用: http://jsfiddle.net/JohannesJo/6ru2R/
JavaScript的:
app = angular.module('app',[]);
app.controller('controller', function($scope){
$scope.aData = [
{i:1},
{i:2}
];
$scope.aSelected = [];
});
HTML:
<body ng-app="app">
<div ng-controller='controller'>
<input type = "checkbox" ng-model = "aSelected" value = "{{aData[0]}}">
<input type = "checkbox" ng-model = "aSelected" value = "{{aData[1]}}">
<div>test: {{oSelected}}</div>
</div>
</body>
答案 0 :(得分:2)
一个选项是监视oSelected
数组上的更改,并根据它创建相关对象列表。
$scope.$watch(function () {
return $scope.oSelected;
}, function (value) {
$scope.selectedItems = [];
angular.forEach($scope.oSelected, function (v, k) {
v && $scope.selectedItems.push($scope.aData[k]);
});
}, true);
