Avoid displaying the image when encountering a 404 error, but sometimes a broken image may still appear momentarily

Here is the code snippet I'm currently using:

<img ng-show="json.user.picture" ng-src="{{json.user.picture}}" ng-error="json.user.picture = false">

When accessing an image from an external website without permission, a 404 error code is returned. In order to prevent showing the broken image, I have implemented the code above which works effectively. However, there is still a brief moment where the broken image is displayed. How can this be eliminated?

There seems to be a slight delay between ng-show and ng-hide which results in the broken image being shown momentarily. Any suggestions on how to fix this?

Answer №1

It appears that the issue lies in using json.user.picture both as the condition to display an image and as the image source. When ng-error is triggered, json.user.picture changes to false, causing the image source to be false and attempting to load an image named false, resulting in an error.

To resolve this, introduce an additional variable like showImage that defaults to true. When an error occurs, set showImage to false and utilize it in ng-show.

Therefore, the solution would be:

<img ng-show="showImage" ng-src="{{json.user.picture}}" ng-error="showImage = false">
