Answer: Use the CSS Attribute Selector You can use the CSS attribute selectors to find an HTML element based on its data-attribute value using jQuery. The attribute selectors provide a very powerful way to select elements.
You can use this jquery data() syntax for get data-id attribute value. $("selector"). data("textval"); You can use this jquery data() syntax for get data-textval attribute value.
You can use the attribute selector: $('[data-my-key]').
The [attribute^="value"] selector is used to select elements with the specified attribute, whose value starts with the specified value. The following example selects all elements with a class attribute value that starts with "top": Note: The value does not have to be a whole word!
Use Attribute Equals Selector
$('.slide-link[data-slide="0"]').addClass('active');
Fiddle Demo
.find()
it works down the tree
Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.
You can also use .filter()
$('.slide-link').filter('[data-slide="0"]').addClass('active');
I searched for a the same solution with a variable instead of the String.
I hope i can help someone with my solution :)
var numb = "3";
$(`#myid[data-tab-id=${numb}]`);
you can also use andSelf() method to get wrapper DOM contain then find() can be work around as your idea
$(function() {
$('.slide-link').andSelf().find('[data-slide="0"]').addClass('active');
}).active {
