Automatically, the "ng-hide" class gets added despite using the correct syntax for ng-show

I am trying to dynamically show/hide a tr tag within a table based on the value of a scope variable in the controller. Despite writing the code correctly, I am facing an issue where the "ng-hide" class is automatically added to the tr tag every time it is rendered.

<div ng-show="IsParentExist">
  <table>
    <thead>...</thead>
       <tbody>
           <tr ng-show="noValueExist">
              <span>There are no records to show here..</span>
           </tr>
           <tr ng-repeat....>
              <td> </td>
           </tr>
        </tbody>
    </table>
 </div>

When the code gets rendered in the DOM, the issue appears as follows:

<div ng-show="IsParentExist">
 <span>There are no records to show here..</span>
  <table>
    <thead>...</thead>
       <tbody>
           <tr class="ng-hide" ng-show="noValueExist">
           </tr>
           <tr ng-repeat....>
              <td> </td>
           </tr>
        </tbody>
    </table>
 </div>

To address this issue, I have defined the scope variable in the controller as shown below:

$scope.noValueExist = true;

Answer №1

Angular automatically adds the ng-hide class to an element until the noValueExist variable is set to true in the controller. Make sure to include the following line in your controller code:

$scope.noValueExist = true;

Answer №2

To improve the visibility of your code, try changing ng-show="noValueExist" to ng-hide="!noValueExist"

<tbody>
    <tr ng-hide="!noValueExist">
        <td>There are no records to show here.</td>
    </tr>
    <tr>
        <td></td>
    </tr>
</tbody>

Make sure to set the initial value in your controller.

$scope.noValueExist = false;

When needed, change the value to true to display the <tr> element.

$scope.noValueExist = true;

Hopefully, this solution will work for you.

One user, @cst1992, pointed out that the problem stemmed from the span not being enclosed within a container.

Answer №4

The issue with the span element misplacement is due to its lack of support inside the 'tr' tag. In order to properly display content within a table, you should utilize the 'td' tag instead.

By replacing the 'span' with the 'td' tag, the content will be correctly rendered in the DOM as shown below.

<div ng-show="IsParentExist" class="ng-hide">
        <table>
            <thead>
                <tr><th>a</th>
                <th>b</th>
            </tr></thead>
            <tbody>
                <tr ng-show="noValueExist" class="ng-hide">
                    <td>There are no records to show here.</td>
                </tr>
                <tr>
                    <td></td>
                </tr>
            </tbody>
        </table>
    </div>
