如何使用敲除数据绑定foreach迭代数组的数组？

Question

I have an array of arrays that contain objects, and im looking for a way to loop over the inner arrays of the array, something like this:

<div data-bind="foreach: questions">
    <div data-bind="foreach: subArray of questions">
        <span data-bind="text: Title"></span>
        <span data-bind="text: Answer"></span>
    </div>
</div>

How can i access the inner arrays of the questions observableArray so i can loop over the elements?

Fiddle example

thanks in advance for any help!

Answer 1

I have updated your fiddle . To use inner loop knockout has provided various properties like $data , to use outer loop $parent .

<div class="answers" data-bind="foreach: questions">
    <div data-bind="foreach: $data ">
      <p data-bind="text: Title"></p>
      <p data-bind="text: Answer"></p>  
    </div>  
</div>

Answer 2

It's all in the docs, you just have to access inner arrays with $data : http://knockoutjs.com/documentation/foreach-binding.html

<div class="answers" data-bind="foreach: questions">
  <div data-bind="foreach: $data ">
    <p data-bind="text: Title"></p>
    <p data-bind="text: Answer"></p>  
  </div>
</div>
