Using both ng-if and ng-click in AngularJS for enhanced functionalities

There's a button that should display a toggle only when the value is greater than 0; otherwise, it shouldn't do anything.

This snippet of code shows how things were prior to adding ng-if:

<span >{{values.valuesNumber}} 
      <i class="fas fa-caret-down" ng-click="$ctrl.doSomething(values)">
      </i>
</span>

The intention is to trigger the function from ng-click only if values.valuesNumber > 0.

To achieve this, I made the following changes but encountered some issues:

<span >{{values.valuesNumber}} <i class="fas fa-caret-down">
     <span ng-if="values.valuesNumber > 0">
         <span ng-click="$ctrl.doSomething(values)">
         </span>
     </span>
 </i></span>

Answer №1

Consider using ng-show over ng-if. This is because ng-if creates its own scope.

<span >{{values.valuesNumber}} <i class="fas fa-caret-down">
     <span ng-show="values.valuesNumber > 0">
         <span ng-click="$ctrl.doSomething(values)">
         </span>
     </span>
 </i></span>
