让我有猫和小猫的人类

   String catName;

   Kitten[] kittens;

                    <!-- ko foreach: kittens -->
<p data-bind="$data.kittenName"></p>
<p data-bind="$parent.catName"></p>
<p data-bind="???????"></p>   <!-- How get master's name? -->
                    <!-- /ko -->
                    <!-- /ko -->
                    <!-- /ko -->

来自knockout documentation

$parents This is an array representing all of the parent view models:

$parents[0] is the view model from the parent context (i.e., it’s the same as $parent)

$parents[1] is the view model from the grandparent context

您应该能够使用 $parents[1] 访问主视图模型。
