如何以编程方式选中带有动态模型名称的复选框? [英] How to programmatically check checkbox with dynamic model name?

问题描述

我创建了一些带有动态模型名称的复选框，如下所示:

I have created a some checkboxes with dynamic model name like this:

<label ng-repeat="item in main.itemDetails">
  <input type="checkbox" checklist-value="item.price"
  ng-click="itemChanged(item)" ng-model="checkboxes[item.name]">
   {{item.name}} - <b>{{item.price}} €</b>
   <br>
</label>

在我的控制器中，我想检查一些复选框，如果它们的模型名称存在于数组$ scope.selectedItems中.

In my controller, I want to check some checkboxes if their model's name exists in array $scope.selectedItems.

我正在尝试做这样的事情，但是它不起作用:

I'm trying to do something like this but it isn't working:

for (var i = 0, j = $scope.selectedItems.length; i<j; i++) {
            $scope['selectedItems[i].name'].isChecked = true;
        }

例如，如果item.name ='Item1'，我希望将模型命名为$ scope.Item1，然后再调用$scope.Item1.isChecked = true;

for example if item.name = 'Item1' I want the model to be named $scope.Item1 and later I want to call $scope.Item1.isChecked = true;

我在这里做什么错了?

推荐答案

您正在将模型存储在$scope.checkboxes中，因此可以像下面的代码一样将其值设置为true.

Your are storing the model in the $scope.checkboxes, so you can set its value to true like the code below.

for (var i = 0, j = $scope.selectedItems.length; i<j; i++) {
    $scope.checkboxes[$scope.selectedItems[i].name] = true;
}
