getElementsByTagName method
The getElementsByTagName method
allows you to get page elements by a tag
name. With the retrieved elements, you
can perform various manipulations: change
their text, attributes, CSS styles, and so
on.
Syntax
document.getElementsByTagName(tag name);
Example
Let's get all the paragraphs and change
their text using the property
innerHTML:
<p>elem 1</p>
<p>elem 2</p>
<p>elem 3</p>
let elems = document.getElementsByTagName('p');
for (let elem of elems) {
elem.innerHTML = '!!!';
}
The code execution result:
<p>!!!</p>
<p>!!!</p>
<p>!!!</p>
