The Ultimate jQuery Guide for Beginners in 2020.

Interactive front-end web development starts with Javascript, and jQuery offers you a simple way to achieve a lot of common javascript tasks. With this article, I’ll hope to teach you the fundamentals of jQuery!

What is jQuery?

jQuery is a JavaScript file that you include in your web pages, and it will let you find elements using CSS-style selectors, and then you can do some things to them using jQuery methods.

<body>
 <div id="page">
  <h1 id="header">Header</h1>
 </div>
<script src="jquery-1.0.js"></script>
<script>
 $('#header').on('click', function() {
  $(this).hide();
 });
</script>
</body>

This simple jQuery code selects the header with the header’s ID and adds an eventListener; if someone clicks this header, it will hide.

In jQuery we use $() as a shortcut for the JQuery() function.

Checking if a page is ready

jQuery has a ready() function to check if your page is ready to work with.

$(document).ready(function(){
  //IF READY THIS WILL BE EXECUTED

});

Getting the element content

In jQuery we use the .HTML() and .text() methods to retrieve and update content of those elements.

.HTML()
