How To Get Jquery Data Attribute

by

In this blog post, we will learn how to get the value of a data attribute using jQuery. Data attributes are a convenient way to store additional information on HTML elements without affecting the presentation or behavior of the element. They are typically used for storing custom data that can be accessed and manipulated by JavaScript or jQuery.

Using the data() method

The most common way to get the value of a data attribute using jQuery is by using the data() method. This method allows you to get or set the values of data attributes on the selected elements.

Here’s the syntax for getting a data attribute value with the data() method:

    
        $(element).data(key);

Where element is the target HTML element, and key is the name of the data attribute without the data- prefix.

Let’s say we have the following HTML markup:

    
        <div id="myElement" data-my-attribute="someValue"></div>

To get the value of the data-my-attribute attribute, we would use the following jQuery code:

    
        var myAttributeValue = $('#myElement').data('my-attribute');

The myAttributeValue variable would now contain the string ‘someValue’.

Using the attr() method

Another way to get the value of a data attribute is by using the attr() method. This method is used to get or set the value of an attribute on the selected elements.

Here’s the syntax for getting a data attribute value with the attr() method:

    
        $(element).attr(attributeName);

Where element is the target HTML element, and attributeName is the full name of the data attribute, including the data- prefix.

Using the same HTML markup as before, we can get the value of the data-my-attribute attribute with the following jQuery code:

    
        var myAttributeValue = $('#myElement').attr('data-my-attribute');

Again, the myAttributeValue variable would contain the string ‘someValue’.

Conclusion

In this blog post, we’ve learned two ways to get the value of a data attribute using jQuery: the data() method and the attr() method. Both methods are easy to use and can help you access custom data stored in your HTML elements.
