I want to read the parent of parent elements data. But, I can't able to read it properly.



My Array Screenshot :



enter image description here



My Code :



<!-- ko foreach: { data: Object.keys($parent.optionParam()[main_id]), as: 'attribute' } -->
<div class="product-custom-option-select">
<p style="font-weight:bold;color:blue" data-bind="text:attribute"></p>
<!-- ko if: Array.isArray(Object.keys($parent.optionParam()[main_id][attribute])) -->
<p style="font-weight:bold;color:green" data-bind="text:attribute"></p>
<!-- ko foreach: $parents[1].optionParam[$parentContext.$index()][attribute] -->
<p class="options-label" data-bind="text:sub_id"></p>
<!-- /ko -->
<!-- /ko -->
<!-- ko if: !Array.isArray($parent.optionParam()[$index][attribute]) -->
<p style="font-weight:bold;color:red" data-bind="text:attribute"></p>
<p class="options-label" data-bind="text:attribute[$parents[1].main_id]"></p>
<!-- /ko -->
</div>
<!-- /ko -->


Using $parent.optionParam()[main_id] I can able to access 0 element array. So, in first <p> tag I get Size text as attribute.



Now, I want to read there are sub-element available in Size or Color, If true then, First Array.isArray() should be true and I can able to read sub_color or sub_id field value.



<!-- ko if: Array.isArray(Object.keys($parent.optionParam()[main_id][attribute])) -->


This line always returns an error to me.



How can I read it?



Any help would be appreciated.

$parent is essentially an array with all the parents in the current context.



So $parent or $parent[0] refers to immediate parent, $parent[1] will refer to grandparent or parent of parent and so on.
