Easily conceal and reveal elements using Svelte in a straightforward manner

I'm looking for a straightforward method to hide and show an element using a button in Svelte. Can someone guide me on how to achieve this? Additionally, I'm curious if it's easier to accomplish this task with vanilla JavaScript.

Answer №1

I found this code to be quite effective in my situation. It's actually a customized version of an example that was originally provided by Svelte. You can check out the original example here

<script>
    let showContent = true;

    function toggleContentVisibility() {
        showContent = !showContent
    }
</script>

<button on:click={toggleContentVisibility}>
    Toggle Content
</button>

{#if showContent}
    <p>
        This content will be hidden.
    </p>
{/if}

Svelte offers a convenient {#if} directive that allows you to connect it with local state, enabling changes through a button's on:click event.

The ease of implementation in vanilla JS varies depending on factors such as complexity. However, in the grand scheme of things, Svelte tends to simplify processes over time.

Original Vanilla JS Example

Check out this example using vanilla JavaScript to toggle content:

This code snippet can be placed directly inside an .astro component:

<button>Toggle</button>

<p>Content</p>

<script>
    document.querySelector('button').onclick = () => {
        const el = document.querySelector('p')
        el.style.display = el.style.display === 'none' ? 'block' : 'none'
    }
</script>

Svelte Solution

Here's an alternative solution using Svelte:

<script>
  let toggle = true
</script>

<button on:click={() => (toggle = !toggle)}> Toggle </button>

{#if toggle}
  <p>Content</p>
{/if}

To ensure the JavaScript is included in the client-side bundle in Astro, import it with a client: directive:

---
import Svelte from "./svelte.svelte";
---

<Svelte client:load />

My Recommendation

If you're looking for readability and scalability, I suggest going with Svelte. It offers a cleaner syntax and better potential for future feature additions.
