如何在离子中选择多个复选框 [英] how to select multiple checkboxes in ionic

问题描述

我正在为我的应用程序开发使用离子框架，并希望在单击标题复选框或按钮时选择多个复选框。

I am using ionic framework for my app development and want to select multiple checkboxes on click of header checkbox or button.

    <ion-list>
      <ion-checkbox ng-model="filter.color">Colors</ion-checkbox>
      <ion-checkbox ng-model="filter.blue">Red</ion-checkbox>
      <ion-checkbox ng-model="filter.yellow">Yellow</ion-checkbox>
      <ion-checkbox ng-model="filter.pink">Pink</ion-checkbox>

      <ion-checkbox ng-model="filter.number">Number</ion-checkbox>
      <ion-checkbox ng-model="filter.one">1</ion-checkbox>
      <ion-checkbox ng-model="filter.two">2</ion-checkbox>
      <ion-checkbox ng-model="filter.three">3</ion-checkbox>
    </ion-list>

当我点击颜色时，应点击所有三个三个复选框。当我取消选中其中任何一个时，Colors也应该被取消选中，只剩下其他两个。

When I click on "Colors", all three three checkboxes should be clicked. And when I uncheck any one of them, "Colors" should be unchecked as well and only the other two should remain.

我使用普通的HTML复选框和javascript实现了这一点，但有点不确定如何做离子。

I achieved this using normal HTML checkboxes and javascript, but a little unsure on how to do it ionic.

请帮助。

谢谢

推荐答案

可能你可以使用这样的东西：

May be you could use something like this:

<ion-list>
   <ion-checkbox ng-model="filter.color" ng-checked="filter.blue && filter.yellow && filter.pink">Colors</ion-checkbox>
   <ion-checkbox ng-model="filter.blue" ng-checked="filter.color">Red</ion-checkbox>
   <ion-checkbox ng-model="filter.yellow" ng-checked="filter.color">Yellow</ion-checkbox>
   <ion-checkbox ng-model="filter.pink" ng-checked="filter.color">Pink</ion-checkbox>
</ion-list>

修改

我发现上面有错误的方法，因为 ngModel 和 ngChecked 一起工作不好。这是工作版本：

I found that above there is wrong approach, because ngModel and ngChecked work bad together. This is working version:

<ion-list>
            <ion-checkbox ng-model="filter.color" ng-change="changeAllColors()">Colors</ion-checkbox>
            <ion-checkbox ng-model="filter.blue" ng-change="checkColors()">Red</ion-checkbox>
            <ion-checkbox ng-model="filter.yellow" ng-change="checkColors()">Yellow</ion-checkbox>
            <ion-checkbox ng-model="filter.pink" ng-change="checkColors()">Pink</ion-checkbox>
        </ion-list>

并且在控制器中：

    $scope.changeAllColors = function () {
            $scope.filter.blue = $scope.filter.yellow = $scope.filter.pink = $scope.filter.color;
   }
        $scope.checkColors = function () {
                $scope.filter.color = $scope.filter.blue && $scope.filter.yellow && $scope.filter.pink;
            }
