上面的代码绑定了每个复选框并显示保存按钮,如果其中任何一个被选中,但现在我在实现主复选框时遇到问题,这将检查所有复选框并显示按钮。
答案 0 :(得分:0)
检查工作演示:Plunker。
添加一个新复选框:
<input type="checkbox" ng-change="toggleCheckAll()" ng-model="allChecked" />
check this to check all checkbox and show the button
每次检查/取消选中此chechbox时,都会调用函数toggleCheckall
。在控制器中:
$scope.allChecked = false;
$scope.toggleCheckAll = function () {
for (var key in $scope.results) {
$scope.results[key] = $scope.allChecked;
}
};
