How to Copy Text to Clipboard

Copying text to the clipboard is a common requirement in modern web applications. While many vanilla JavaScript solutions exist, today we’ll use Clipboard.js , a lightweight library, and Hint.css , a simple tooltip library, to create an elegant copy-to-clipboard feature.

Step 1: HTML Structure

The HTML remains the same. It includes a link styled with Hint.css to show a tooltip when hovering over the copy icon.

<a href="#">



<ul>
<li>
<strong>class="hint hint-bottom"</strong> : Adds a bottom-aligned tooltip using Hint.css.</li>
<li>
<strong>data-hint="Copy link to clipboard"</strong> : The tooltip text.</li>
</ul>

<h3>
  
  
  Step 2: JavaScript
</h3>

<p>Here’s the updated code in plain JavaScript:<br>
</p>

<pre class="brush:php;toolbar:false">// Select the clipboard control
const control = document.querySelector('.app-clipboard-link');

// Set the clipboard text
control.setAttribute('data-clipboard-text', 'https://google.com');

// Initialize Clipboard.js
const clipboard = new ClipboardJS(control, {
    text: (trigger) => trigger.getAttribute('data-clipboard-text'),
});

// Handle the success event
clipboard.on('success', (event) => {
    // Update the tooltip to show "Copied"
    control.setAttribute('data-hint', 'Copied');

    // Reset the tooltip after 3 seconds
    setTimeout(() => {
        control.setAttribute('data-hint', 'Copy link to clipboard');
    }, 3000);
});

Explanation of the Code

• This sets the data-clipboard-text attribute dynamically to the desired URL.
• text: Defines a callback function that returns the value of the data-clipboard-text attribute for the clicked element.
• Updates the tooltip to "Copied" when the clipboard action is successful.
• Resets the tooltip text back to "Copy link to clipboard" after 3 seconds.

Handling the Success Event :

clipboard.on('success', (event) => {
    control.setAttribute('data-hint', 'Copied');
    setTimeout(() => {
        control.setAttribute('data-hint', 'Copy link to clipboard');
    }, 3000);
});

Initializing Clipboard.js :

const clipboard = new ClipboardJS(control, {
    text: (trigger) => trigger.getAttribute('data-clipboard-text'),
});

Setting the Clipboard Text :

control.setAttribute('data-clipboard-text', 'https://google.com');
