angularjs ng-repeat with dynamic json/object

Question

I am looking a solution for dynamic data structure(inconsistent like different property name and property length) with ng-repeat. sample code are below.

    $scope.data = [{
        "table":[{
        "employee":"name1",
        "value1":"10",
        "value2":"20"
        },
        {
        "employee":"name2",
        "value1":"15",
        "value2":"30"
        }]
    },
    {
        "table":[{
        "company":"name1",
        "compnayValue":"12"
        },
        {
        "company":"name2",
        "compnayValue":"12"
        }]
    }]

    <ul>
        <li ng-repeat="item in data">
            <table>
                <tr ng-repeat="row in item.table">
                    <td>{{??}}</td>
                    <td>{{??}}</td>
                </tr>
            </table>
        </li>
    </ul>

What exactly do you want to display in those {{??}} for example? what is the desired output based on the shared data? — T J

either its a {{row.employee}} or {{row.company}}, so my question is how could i handle these dynamic property name? — Jaison James

so you don't want to display other properties like value1, compnayValue etc? What is the criteria for picking which property to display? — T J

Yes, I want display all property, just answered for you only with the example. — Jaison James

You could enumerate all properties and display their values by another ng-repeat on td:

<li ng-repeat="item in data">
  <table>
    <tr ng-repeat="row in item.table">
      <td ng-repeat="(key, value) in row">
        {{row[key]}}
      </td>
    </tr>
  </table>
</li>

but that would break the tabular format of data since some rows would have more tds. To prevent that you could first find out the set of all keys on all rows, do a th repeat with those first and then display them on the corresponding td below, e.g.:

<th ng-repeat="propertyName in allPossiblePropertyNames">
  {{propertyName}}
</th>

and

<td ng-repeat="propertyName in allPossiblePropertyNames">
  {{row[propertyName ]}}
</td>

Use <tbody> to represent an object inside table array and (key,value) syntax mentioned in iterating over object properties section to iterate over it's properties like:

angular.module('test', []).controller('testCtrl', function($scope) {
  $scope.data = [{
    "table": [{
      "employee": "name1",
      "value1": "10",
      "value2": "20"
    }, {
      "employee": "name2",
      "value1": "15",
      "value2": "30"
    }]
  }, {
    "table": [{
      "company": "name1",
      "compnayValue": "12"
    }, {
      "company": "name2",
      "compnayValue": "12"
    }]
  }]
});

ul {
  padding: 0;
}
ul li {
  list-style-type: none;
  margin-bottom: 10px;
}
table {
  width: 100%;
  table-layout: fixed;
  background: #ebebeb;
}
tbody:nth-child(odd) tr {
  color: #fff;
  background: dodgerblue;
}
tbody:nth-child(even) tr {
  color: #fff;
  background: hotpink;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="test" ng-controller="testCtrl">
  <ul>
    <li ng-repeat="item in data">
      <table>
        <tbody ng-repeat="row in item.table">
          <tr ng-repeat="(key, value) in row">
            <td>
              {{key}}
            </td>
            <td>
              {{value}}
            </td>
          </tr>
        </tbody>
      </table>
    </li>
  </ul>
</div>

Check this plunker, you can define template depends on your data : https://plnkr.co/edit/fVGhKZy5gnBzuPwspy5s?p=preview

Use angular filter :

app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.data = [{
      "table":[{
      "employee":"name1",
      "value1":"10",
      "value2":"20"
      },
      {
      "employee":"name2",
      "value1":"15",
      "value2":"30"
      }]
  },
  {
      "table":[{
      "company":"name1",
      "compnayValue":"12"
      },
    {
    "company":"name2",
    "compnayValue":"12"
    }]
  }]
 })
  .filter('isCompnay', function() {
   return function(input) {
   console.log(input.employee === undefined)
   return input.company ? input : undefined;
  };
})
.filter('isEmployee', function() {
return function(input) {
  console.log(input.employee === undefined)
  return input.employee ? input : undefined;
   };
 });
