How to get the value of an attribute using JavaScript
To get the value of an attribute of an element, you can use the getAttribute() method. This method returns the value of the attribute with the specified name. If the attribute does not exist, it returns null or an empty string ('').
Let us say you have the following anchor element:
<a href='http://example.com' title='Go Back' data-role='self'>Click Me</a>
Now you want to get the value of the href attribute. Here is a code snippet that you can use:
const anchor = document.querySelector('a');
const href = anchor.getAttribute('href');
console.log(href); // http://example.com
The getAttribute() method also works for the HTML5 data-* attributes.
For example, to get the value of the data-role attribute of the anchor element, you can use the getAttribute() method as follows:
const anchor = document.querySelector('a');
const role = anchor.getAttribute('data-role');
console.log(role); // self
If you want to get the value of the attribute as an Attr object, use the getAttributeNode() method instead:
const anchor = document.querySelector('a');
const attr = anchor.getAttributeNode('title');
console.log(attr.value); // Go Back
The getAttribute() method works in all modern browsers, and IE9 and up.
