Guide on creating and dynamically appending an element to the DOM in VueJS triggered by a user clicking a button

I'm having an issue with my vue webapp. I want to make a square shape appear on the screen where a user clicks, but for some reason, my code isn't working as intended. Can someone help me figure out what's wrong?

<template>
    <div class="shapepage" @click="attachShape"></div>
</template>

<script>
export default {
    name: "ShapePage",
    methods: {
        attachShape: (e) => {
            render:  (createElement) => {
                return createElement('div', {
                    style: {
                        width: "100px",
                        height: "100px",
                        background: "red",
                        color: "white",
                        position: "absolute",
                        left: "50",
                        top: "50"
                    }
                });
            }
        }
    }
}
</script>

<style>
body {
    background-color: rgba(245, 245, 245, 1);
}

.shapepage {
    margin-top: 20px;
    max-width: 500px;
    height: 500px;
    margin-left: auto;
    margin-right: auto;
    background-color: #fff;
    box-shadow: 0px 0px 5px 1px grey;
}
</style>

Answer №1

I believe that the render function functions similarly to data() in a way that limits its usage,
If my assumption is correct, the render function may resemble React.js's render, producing a VNode Tree and defaulting to Vue's template for refreshing VNodes
I trust this explanation aids your understanding
