When both ng-mouseover and ng-mouseleave are triggered simultaneously

Question

When both ng-mouseover and ng-mouseleave are triggered simultaneously

My goal is to toggle the visibility of an image tag. When the mouse hovers over it, the image should disappear and when the mouse moves away, the image should reappear.

Here's what I've attempted:

<img ng-mouseover="active = true" ng-mouseleave="active = false"
     ng-init="active = true" ng-show="active">

The issue arises when the mouse hovers over the image, causing the ng-mouseleave event to trigger simultaneously, resulting in a blinking loop effect.

I tried resolving this problem using directives, but unfortunately, encountered the same outcome.

From what I can see, it appears that your implementation is causing the mouseleave event to trigger automatically after hiding the element when you hover over it. It seems that when the element is hidden using the ng-show expression, it also somehow simulates the mouse leaving the element. This results in a continuous loop where the element keeps toggling visibility due to the mouse events.

To avoid this issue, you might want to consider using the CSS property opacity instead of relying on ng-show. Additionally, it looks like your code is achieving the opposite effect of what you intended.

I gave your suggested solution a try and it seems to be working as expected now.

<img ng-style="{'opacity': active ? 1 : 0}"  ng-mouseover="active = false" ng-mouseleave="active = true" ng-init="active=true">

I decided to enclose the <img> element within an <a> tag in order for the <a> tag to capture mouse events and manipulate the active variable as shown below:

<a ng-mouseenter="active = false" ng-mouseleave="active = true"  href="#" >
    <img  ng-init="active = true" ng-show="active" src="/path.jpg" alt=""> 
</a>
