QuerySelector attribute contains Example using JavaScript #

To get the DOM elements by partially matching an attribute value, pass the following selector to the querySelectorAll method - '[title*="box"]'. The selector matches all of the DOM elements that have a title attribute that contains the string box.

Here is the HTML for the examples in this article.

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> </head> <body> <div title="box1">Box 1</div> <div title="box2">Box 2</div> <script src="index.js"></script> </body> </html>

And here is the related JavaScript code.

const boxes = document.querySelectorAll('[title*="box"]'); console.log(boxes); // 👉️ [div, div] const box = document.querySelector('[title*="box"]'); console.log(box); // 👉️ div

We used the document.querySelectorAll method to select all of the DOM elements that have a title attribute that contains the string box.

The string can be located anywhere in the attribute's value to match the query.

The second example uses the document.querySelector method, which returns the first element within the document that matches the provided selector.

In short, if you're looking for a single element that matches the provided selector, use querySelector(), and if you're looking for a collection of elements, use querySelectorAll().

You can also make the query more specific by only looking for div elements that have an attribute that contains the string box.

const boxes = document.querySelectorAll('div[title*="box"]'); console.log(boxes); // 👉️ [div, div] const box = document.querySelector('div[title*="box"]'); console.log(box); // 👉️ div

The selectors we passed to the querySelectorAll and querySelector methods would not not match any span or p elements even if they have a title attribute that contains the string box.
