Vue component fails to trigger upon receiving the 'mouseleave' event

I am currently working on a navbar with dynamic component navigation, where hovering over a navbar-link should display the corresponding component and hiding it when the mouse leaves. Although the components are displayed correctly upon hover, they do not disappear or respond to the "mouseleave" event as expected. Here is an example of the code being used:

Even after trying other events like @click, the issue persists.

<keep-alive>
  <component :is="selectedComponent" v-if="showComponent"  @mouseleave="showComponent = false"></component>
</keep-alive>

The desired outcome is for the component to disappear on mouseleave.

Answer №1

Implementing an event listener on a component means it will only respond to events emitted by that specific component through $emit. If you do not trigger this.$emit('mouseleave') within your component, the listener will never be activated.

To handle this internally and emit the event, you may consider using the native modifier, which directly links DOM events to the outermost component element:

@mouseleave.native="showComponent = false"

https://v2.vuejs.org/v2/guide/components-custom-events.html#Binding-Native-Events-to-Components

It is worth noting that components behave differently from native HTML elements in this context. While your approach would have functioned correctly with a <div>, it will not produce the desired outcome for a component.
