How to iterate json collection using ng repeat angularjs

Question

My service gives below json result

 {"categories":[{"category_id":"20","name":"Desktops"},  {"category_id":"18","name":"Laptops &amp},{"category_id":"25","name":"Components"},
{"category_id":"57","name":"Tablets"},
{"category_id":"17","name":"Software"},
{"category_id":"24","name":"Phones} ]}

this is my html code:

    <tr ng-repeat="menu in menuitems">
    <td>
        {{menu.name}}
    </td>

in controller I fill $scope.menuitems with the json result

I am not able to render the list of names in html. If I write {{menu[0].name}} I do get one record.What am i doing wrong that I am unable to iterate over the json collection.

ng-repeat directive works over an array.

So, in your case menuitems is the variable where you store the response json object.

Your json's structure shows that it contains an array categories of objects.

Therefore, for ng-repeat to work, you need to pass in menuitems.categories to it.

Expression:

<tr ng-repeat="menu in menuitems.categories">
<td>
    {{menu.name}}
</td>

It is inside an object. So, you must use,

 <tr ng-repeat="menu in menuitems.categories">
<td>
    {{menu.name}}
</td>

You should iterate all objects and track them I dont know about your controller but try add this line of code

ng-repeat="menu in menuitems track by $index
