<p>I'm working on angular js with python flask and I'm facing one challenge to iterate through JSON in one scenario. The scenario is as below:
JSON is: </p>

<pre><code>{
    "categories": ["ladies", "men", "kids", "home", "sale", "life"],
    "home": [{
        "categories": "New Arrivals",
        "categoryTitle": "home"
    }],
    "kids": [{
        "categories": "New Arrivals",
        "categoryTitle": "Baby"
    }],
    "men": [...multiple nodes...],
    "ladies": [...multiple nodes...]
}
</code></pre>

<p>I want to print data from categories json e.g. kids.categoryTitle but my category names are coming dynamically from categories list in the same json.</p>

<p>What I'm trying to print is:</p>

<pre><code>&lt;div ng-repeat="catName in ctrl.tableData.cats"&gt;&lt;tr data-ng-repeat="(key, data) in ctrl.tableData.catName"&gt;&lt;/tr&gt;&lt;/div&gt;
</code></pre>

<p>But the above code is not working where as if I use <code>ctrl.tableData.kids1 instead of</code>ctrl.tableData.catName1 it works.</p>

<p>Thanks for your help</p>
