How to get the data from meta tags in JavaScript

In this tutorial, we are going to learn how to get the meta tags data using JavaScript.

Consider we have the following meta tags in our index.html file.

<meta name="title" content="My first post" />
<meta name="description" content="A description of the my post" />

To get the above meta tags data, we can use the document.querySelector() method by passing [attribute = value] as an argument.

Example:

const title = document.querySelector('[name=title]');
const description = document.querySelector('[name=description]');

console.log(title.content); // My first post
console.log(description.content); // A description of the my post

Similarly, we can also create our own reusable function.

function getMetaData(attr,val){
  return document.querySelector(`[${attr}=${val}]`).content;}

console.log(getMetaData('name','title')); // My first post
