Vue scope: how to delay handling of @mouseover

Question

So I want to have an action only if the user has the mouse on the div for at least 1 second. Inside template:

<div @mouseover="trigger"></div>

Inside script:

data() {
    return {
        hovered: false
    }
}

methods: {
    trigger() {
        setTimeout(function(){ this.hovered = true }, 1000)
    }
}

My problem is that I don't understand the scope of Vue. Because this.hovered is inside another function, it does not find the actual hovered data variable. What's the solution to this?

Answer 1

Have you tried using an arrow function in your setTimeout? It will maintain this.

data() {
    return {
        hovered: false
    }
}

methods: {
    trigger() {
        setTimeout(() => { this.hovered = true }, 1000)
    }
}
