AngularJS: displaying table columns before data arrival

Is there a way to ensure that AngularJS renders table columns correctly even before receiving the actual content for them?

I have been using ng-if to display the content, as I need different elements based on the value returned from an API call. This is why I haven't used ng-bind, which might seem like a more appropriate solution.

<td ng-if="someArray.length > 0"><a ng-href="someLink">Yes</a></td>
<td ng-if="someArray.length == 0">No</td>

With this approach, the column in question does not appear at all when someArray is uninitialized. I could include a check for undefined in the second ng-if, but I would prefer the column to remain empty until a value is received. I am still relatively new to AngularJS and I believe there must be a best practice for handling this situation.

Answer №1

To show or hide elements based on conditions within the DOM, you can utilize ng-if.

<section>
  <a ng-if="someArray.length > 0" ng-href="someLink">Display when array is not empty</a>
  <p ng-if="someArray.length == 0">This will appear if array is empty</p>
</section>

Answer №2

To reorganize the code, consider moving the ng-if statements directly into the elements within the td:

<td>
    <a ng-if="someArray.length > 0" ng-href="someLink">Yes</a>
    <span ng-if="someArray.length == 0">No</span>
</td>
