Implementing Conditional ng-src Loading based on a Given Value

I have a dropdown menu that contains a list of image names. When an image is selected, it should be loaded and displayed using the ng-src directive. Everything works perfectly fine when a name is chosen.

The issue arises when the dropdown menu also includes an empty value. If this empty option is selected, the ng-src event attempts to load an image with no filename, resulting in a 404 error because the resource cannot be found by the server.

GET http://..../api/images/logo/ 404 (Not Found)

My question is: How can I prevent the loading event from triggering when the user selects the empty value?

javascriptangularjs

Answer №1

If no image is selected, you have the option to add a condition to ng-src in order to display a default image. It can be implemented like so:

<img ng-src="{{ image || 'default-image.jpg' }}" />

Answer №2

After taking the advice from the feedback, implementing an ng-if successfully resolved the issue by eliminating the img tag within the document structure.
