How To Get A Style Attribute From A Css Class By Javascript Jquery

If you've ever needed to access the style attribute of a CSS class using JavaScript or jQuery, you're in luck! This handy guide will walk you through the process step by step to help you achieve your coding goals.

First things first, if you want to extract the style attribute of a CSS class, you need to understand the principles behind it. CSS classes provide a way to apply styling to multiple HTML elements with a single declaration. JavaScript and jQuery can be powerful tools to manipulate these styles dynamically.

To retrieve the style attribute of a specific CSS class, you will need to follow these simple steps. Let's start with JavaScript:

1. Identify the targeted element: Begin by selecting the element that has the CSS class whose style attribute you want to retrieve. You can do this using the `document.querySelector()` method and passing the CSS class selector as an argument.

const element = document.querySelector('.your-css-class');

2. Access the computed style: Once you have the element selected, you can use the `window.getComputedStyle()` method to access the computed styles of the element. This method returns an object that represents the final computed values of all CSS properties of the element.

const styles = window.getComputedStyle(element);

3. Retrieve the specific style attribute: With the computed styles available, you can now retrieve the value of a specific style attribute by using the `getPropertyValue()` method on the `styles` object. Simply pass the name of the style attribute as an argument.

const specificStyle = styles.getPropertyValue('style-attribute-name');

And that's it for JavaScript! Now let's see how you can accomplish the same task using jQuery:

1. Select the element: Just like in JavaScript, start by selecting the element with the desired CSS class using jQuery's selector.

const element = $('.your-css-class');

2. Retrieve the style attribute: jQuery provides a convenient method called `css()` that allows you to retrieve the value of a CSS property for the selected element. Pass the name of the style attribute as an argument to the `css()` method.

const specificStyle = element.css('style-attribute-name');

By following these straightforward steps, you can effortlessly get the style attribute of a CSS class using JavaScript or jQuery. Whether you prefer the simplicity of JavaScript or the convenience of jQuery, both methods offer effective ways to access and manipulate CSS styles dynamically in your web projects. Happy coding!
