Using Jquery To Know When Font Face Fonts Are Loaded

Ensuring that fonts load correctly on a website is crucial for creating a polished and professional user experience. With the widespread use of web fonts like Font Face in modern web development, it's essential to know when these fonts have finished loading to prevent layout issues or readability problems. In this guide, we'll explore how you can use jQuery to detect when Font Face fonts have fully loaded on your web page.

Firstly, let's understand the significance of Font Face fonts. These are custom fonts that can be embedded on a webpage using CSS. Unlike standard web-safe fonts, Font Face fonts require additional time to load because they need to be downloaded from the server before they can be displayed.

One challenge developers face is that there is no built-in event in JavaScript to notify them when Font Face fonts have finished loading. Fortunately, jQuery can come to the rescue by providing a reliable way to detect the font load completion.

To begin, you'll need to include the jQuery library into your web page. You can either download the jQuery library and host it on your server or use a CDN link to include it. Here's a simple example of how to include jQuery using a CDN link:

Next, you can use jQuery to check the font load status. You can achieve this by creating a hidden element on your page, setting its font to the Font Face font you want to check, and then checking the computed style of that element. If the font has finished loading, the computed style will reflect that.

Here's a basic example of how you can accomplish this with jQuery:

<div id="fontCheck" style="font-family: 'YourFontFaceFont', sans-serif">Lorem ipsum</div>


$(document).ready(function() {
    var fontCheck = $('#fontCheck');
    var interval = setInterval(function() {
        var fontLoaded = fontCheck.css('font-family');
        if (fontLoaded === 'YourFontFaceFont') {
            clearInterval(interval);
            // Font has loaded, you can now proceed with your code
            console.log('Font loaded successfully!');
        }
    }, 100);
});

In this code snippet, we create a hidden div element with the Font Face font applied to it. We then use a setInterval function to check the computed font-family style every 100 milliseconds. Once the Font Face font is detected as fully loaded, we clear the interval and proceed with our code execution.

By following these steps and leveraging the power of jQuery, you can ensure that your Font Face fonts load seamlessly on your website, providing a consistent and visually appealing experience for your users. Remember to test your implementation across different browsers to ensure compatibility. Happy font loading!
