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.
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.
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.
I strongly suggest going through the tutorial for more insights...
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>
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 />
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.
