using ng-show to display array elements

There is a syntax error showing up on the console for the code below, but it still functions as intended. Can someone help identify what I might be missing?

<p class="light" data-ng-show="selectedAppType in ['A1','A2','A3','A4'].indexOf(selectedAppType) > -1">
    You have selected <b>{{selectedAppName}}.</b><br/>
    Please select a <b> {{selectedAppName}} </b> Type.
    <br/>
    <b>Please refer to the console for any errors.</b>
  </p>

Answer №1

selectedAppType must be one of the following values: 'A1', 'A2', 'A3', or 'A4' for this condition to evaluate to true.

This section seems redundant and confusing. It appears that you are trying to check if selectedAppType is within an array, but the way it's written may lead to misunderstanding. It could either be attempting to verify if selectedAppType is located at a certain index (result of indexOf), or if selectedAppType exists within a boolean evaluation (result of the comparison with > -1).

To clarify and simplify, consider using either

selectedAppType in ['A1','A2','A3','A4']

or

['A1','A2','A3','A4'].indexOf(selectedAppType) > -1
