What Is jQuery?<\/h2>\n
jQuery is a JavaScript library used for creating dynamic front-end components, such as rotating sliders. Its lightweight code enables web developers to manipulate HTML elements and validate data more efficiently.<\/p>\n <\/div>\n\n\n\n<\/p>
Why Use jQuery<\/h2>
Apart from its plugin ecosystem, other reasons to use a jQuery library in WordPress are:<\/p>
- \n
- Beginner-friendly<\/strong>. Since it uses a simple and short text format, jQuery code is easy to read and write.<\/li>\n\n\n\n
- Compactness<\/strong>. A jQuery file is usually smaller than plain JavaScript, letting you perform the same tasks with fewer characters.<\/li>\n\n\n\n
- Cross-browser compatibility<\/strong>. Popular browsers that support jQuery include Google Chrome<\/strong>, Microsoft Edge<\/strong>, Mozilla Firefox<\/strong>, Safari<\/strong>, and Opera<\/strong>.<\/li>\n\n\n\n
- AJAX support<\/strong>. Developers can implement AJAX<\/a> to build a responsive and user-friendly website.<\/li>\n\n\n\n
- Lower bandwidth usage<\/strong>. jQuery can execute animation effects directly on the user’s browser, resulting in lower bandwidth usage.<\/li>\n<\/ul>
How to Use jQuery in WordPress<\/h2>
There are two ways of adding jQuery scripts to a WordPress site – manually or using a WordPress plugin.<\/p>

<\/a><\/figure>Let’s start with the manual method.<\/p>
Adding jQuery Manually<\/h3>
If you have experience with JavaScript and WordPress development, follow these steps:<\/p>
1. Switch to the Compatibility Mode<\/strong><\/p>
Before you start adding your own custom jQuery scripts to WordPress, it’s crucial to understand jQuery’s compatibility mode.<\/p>
By default, jQuery uses the $ <\/strong>sign as a shortcut:<\/p>
$(document) .ready (function() {\n$(\"button\") .click (function () {<\/pre>However, other JavaScript libraries on your site also implement the dollar sign in their syntax. To avoid conflicts, enter the compatibility mode by replacing the $ <\/strong>sign with jQuery<\/strong>.<\/p>
Take a look at the following code:<\/p>
jQuery(document) .ready (function() {\njQuery(\"button\") .click (function () {<\/pre>The only problem with this mode is, writing jQuery <\/strong>instead of the shortcut means incorporating more characters, leading to bloated scripts.<\/p>
To solve this issue, pick a new variable name to replace the dollar sign. The most common one is $j.<\/strong><\/p>
Simply add this code at the top of your jQuery scripts:<\/p>
var $j = jQuery.noConflict()<\/pre>
2. Make a Script File<\/strong><\/p>
After that, create a custom script file with the .js extension. Hostinger users can follow these steps:<\/p>
\n\n\n
Important!<\/strong> For beginners, we recommend creating a WordPress child theme<\/a> first. This way, you can customize the styling, layout parameters, and scripts without changing the parent theme directory.<\/p><\/div>\n\n\n\n<\/p>

- Access hPanel <\/strong>→ Hosting <\/strong>→ Manage<\/strong>.<\/li>\n\n\n\n
- On the left menu, select Files <\/strong>→ File Manager<\/strong>.<\/li>\n\n\n\n
- Enter public_html<\/strong> → wp-content<\/strong>.<\/li>\n<\/ol>

<\/a><\/figure><\/div>- \n
- Open the themes<\/strong> folder <\/strong>and select one of the installed themes.<\/li>\n\n\n\n
- On the left menu, click New Folder<\/strong> and name the folder js<\/strong>.<\/li>\n\n\n\n
- Click New File<\/strong> to create a new .js file – for instance: new_script.js<\/strong>.<\/li>\n<\/ol>
\n![\"Newly](\"\/tutorials\/wp-content\/uploads\/sites\/2\/2023\/01\/Newly-created-.js-file-in-the-theme_s-folder-1024x214.png\")

- Add jQuery scripts to the file.<\/li>\n\n\n\n
- Repeat the same steps to customize WordPress plugins.<\/li>\n<\/ol>

3. Add Code Into the functions.php File<\/strong><\/p>
Before adding inline scripts to WordPress, locate the functions.php<\/strong> file in the theme’s folder.<\/p>
![\"The](\"\/tutorials\/wp-content\/uploads\/sites\/2\/2023\/01\/The-functions.php-file-in-the-theme_s-folder-1024x341.png\")
<\/a><\/figure>Open the file and add the following jQuery function at the top:<\/p>
function add_my_scripts() {\r\n wp_enqueue_script( ‘new-script', get_template_directory_uri() . '\/js\/new_script.js', array( 'jquery' ), '1.0.0', true );\r\n}\r\nadd_action( 'wp_enqueue_scripts', 'add_my_scripts' )<\/pre>Make sure to replace new-script<\/strong> and new_script.js<\/strong> with the actual file names.<\/p>
By inserting the wp_enqueue_script<\/strong> function into the PHP code, users can add a custom script and inform WordPress that it relies on jQuery.<\/p>
It also helps WordPress locate the script file and customize the theme based on your jQuery scripts.<\/p>
Adding jQuery via a WordPress Plugin<\/h3>
If adding scripts to WordPress manually is too technical for you, we recommend using jQuery WordPress plugins.<\/p>
Here’s how:<\/p>
1. Pick a Plugin<\/strong><\/p>
WordPress offers various plugins to create interactive websites with jQuery. Here are our top picks for different use cases:<\/p>
- \n
- jQuery Updater<\/a>. While jQuery comes pre-loaded with WordPress, the platform often uses an outdated version. jQuery Updater ensures that your site automatically installs the latest version of this JavaScript library.<\/li>\n\n\n\n
- Advanced Custom Fields<\/a>. This tool is suitable for adding custom fields to posts and pages. Some of its jQuery-based fields<\/a> include Color Picker, Google Map, Date Picker, and Time Picker.<\/li>\n\n\n\n
- jQuery Validation For Contact Form 7<\/a>. This plugin lets you display error messages when users enter invalid data on Contact Form 7<\/a>. You can create validation rules for URLs, dates, credit cards, and phone numbers.<\/li>\n\n\n\n
- jQuery Post Splitter<\/a>. Compatible with most WordPress themes, this plugin lets you split posts and pages into sliders.<\/li>\n<\/ul>
Although installing these plugins<\/a> simplifies the website designing process, you still need a basic knowledge of JavaScript and jQuery libraries to use them.<\/p>
