Using @mouseover Directive

In this approach, we are using the @mouseover directive in Vue.js to trigger the mouseOverFn method when the mouse hovers over the specified element. The method sets a message and shows it for 1 second before hiding it when the mouse leaves the element.

Syntax:

<div @mouseover="methodName">...</div>

Example: The below example uses @mouseover Directive to call a function with Mouse Hover in VueJS.

HTML

<!DOCTYPE html>

<head>
    <title>
        Example 1
    </title>
    <script src=
"https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js">
    </script>
    <style>
        .styled-link {
            color: green;
            text-decoration: underline;
            cursor: pointer;
        }
    </style>
</head>

<body>
    <div id="app">
        <h1>
            Using @mouseover Directive
        </h1>
        <div @mouseleave="mouseLeaveFn" 
            @mouseover="mouseOverFn" 
            class="styled-link">
            Hover over me!
        </div>
        <p v-show="showMessage"> 
            {{ message }} 
        </p>
    </div>
    <script>
        new Vue({
            el: '#app',
            data: {
                message: '',
                showMessage: false
            },
            methods: {
                mouseOverFn() {
                    if (!this.showMessage) {
                        this.message = 
                            'Hello GFG! Message from Function';
                        this.showMessage = true;
                        setTimeout(() => {
                            this.showMessage = false;
                        }, 1000);
                    }
                },
                mouseLeaveFn() {
                    this.showMessage = false;
                }
            }
        });
    </script>
</body>

Output:

Using @mousemove Directive

In this approach, we are using the @mousemove directive in Vue.js to trigger the handleMouseMove method when the mouse is moved over the specified element. The method sets a message and shows it for 1.5 seconds before hiding it when the mouse leaves the element.

Syntax:

<div @mousemove="methodName">...</div>

Example: The below example uses @mousemove Directive to call a function with Mouse Hover in VueJS.
