In React, what’s the difference between onChange and onInput?

When working with React, you may come across two event handlers, onChange and onInput. While they may seem similar, there are some key differences between the two.

The onChange event handler is triggered when the value of an input element changes. This means that the event will only fire when the user has finished making a change and moves focus away from the input field. It is commonly used with form elements like , </code>, and <code><select></code>.</p> <p>Here’s an example of how to use <code>onChange</code> in React:</p> <pre><code>{`import React, { useState } from 'react'; function MyComponent() { const [value, setValue] = useState(''); const handleChange = (event) => { setValue(event.target.value); }; return ( <input type="text" value={value} onChange={handleChange} /> ); }`}</code></pre> <p>The <code>onInput</code> event handler, on the other hand, is triggered whenever the value of an input element changes, regardless of whether the user has finished making a change or not. This means that the event will fire as the user types or makes any changes to the input field. It is commonly used when you need to track changes in real-time, such as for live search or character count.</p> <p>Here’s an example of how to use <code>onInput</code> in React:</p> <pre><code>{`import React, { useState } from 'react'; function MyComponent() { const [value, setValue] = useState(''); const handleInput = (event) => { setValue(event.target.value); }; return ( <input type="text" value={value} onInput={handleInput} /> ); }`}</code></pre> <p>It’s important to note that while <code>onChange</code> is triggered after the user finishes making a change, <code>onInput</code> is triggered as the user types or makes any changes. Depending on your use case, you may choose one over the other.</p> <p>So, to summarize:</p> <ul> <li><code>onChange</code> is triggered when the value of an input element changes and the user moves focus away from the input field.</li> <li><code>onInput</code> is triggered whenever the value of an input element changes, regardless of whether the user has finished making a change or not.</li> </ul> <p>Both event handlers can be useful in different scenarios, so choose the one that best suits your needs.</p> <div class="sharedaddy sd-sharing-enabled"><div class="robots-nocontent sd-block sd-social sd-social-icon-text sd-sharing"><h3 class="sd-title">Share this:</h3><div class="sd-content"><ul><li class="share-facebook"><a rel="nofollow noopener noreferrer" data-shared="sharing-facebook-2567" class="share-facebook sd-button share-icon" href="https://js-duck.com/in-react-whats-the-difference-between-onchange-and-oninput/?share=facebook" target="_blank" title="Click to share on Facebook" ><span>Facebook</span></a></li><li class="share-x"><a rel="nofollow noopener noreferrer" data-shared="sharing-x-2567" class="share-x sd-button share-icon" href="https://js-duck.com/in-react-whats-the-difference-between-onchange-and-oninput/?share=x" target="_blank" title="Click to share on X" ><span>X</span></a></li><li class="share-end"></li></ul></div></div></div><div class='yarpp yarpp-related yarpp-related-website yarpp-template-list'> <!-- YARPP List --> <h3>Related Posts:</h3><ol> <li><a href="https://js-duck.com/react-js-identifying-different-inputs-with-one-onchange-handler/" rel="bookmark" title="React.js: Identifying different inputs with one onChange handler">React.js: Identifying different inputs with one onChange handler</a> <br/><small>React.js: Identifying different inputs with one onChange handler When working with forms in React.js, it is common to have multiple…</small></li> <li><a href="https://js-duck.com/react-js-onchange-event-for-contenteditable/" rel="bookmark" title="React.js: onChange event for contentEditable">React.js: onChange event for contentEditable</a> <br/><small>React.js: onChange event for contentEditable React.js is a powerful JavaScript library that allows developers to build user interfaces efficiently.
