我想在Ionic复选框中选择所选项目。因此,当用户选中复选框时,我想知道他/她选择了哪本书。
以下是我的代码段:
int i;
scanf("%d", &i);
scanf("%d", &i); // it remembers*, so it reads the next integer
运行代码时,它看起来像这样:
我想使用ng-model但我不知道如何使用它。有人可以帮助我,因为我是Ionic和AngularJS的新手,谢谢!
更新: 非常抱歉,我没有提供控制器的代码片段,以下是代码:
<ion-item ng-repeat="book in data.books">
<div style="margin-left:110px;margin-right:10px;">
{{book.name}}
</div>
<li class="item item-checkbox checkbox-balanced">
<label class="checkbox">
<input type="checkbox">
</label>
</li>
</ion-item>

您可以在每个值中包含 checked
的变量,并将其作为 model
变量绑定到复选框

var clubApp = angular.module('clubApp', ['ionic'])
clubApp.controller('ctrlPlayer', ['$scope', function($scope) {
$scope.books = [{
"name": "And the goog news is",
"checked": false
}, {
"name": "Girl on the train",
"checked": false
}];
$scope.getselected = function(){
angular.forEach($scope.books,function(key,value){
if(key.checked ==true)
{
alert(key.name);
}
});
}
}]);
