Basic Understanding of jQuery

JQuery is cross-platform and feature-rich JavaScript library that supports different browsers. It is fast and where you can write less and do more. JQuery takes a lot of common task that JavaScript takes many lines of codes to execute. JQuery improves the performance of an application. JQuery is the most popular frameworks out of lots of JavaScript frameworks.

There are two ways adding jQuery to your web page:

  • Download the jQuery library from jQuery.com
  • Include jQuery from a CDN

All the references should be with HTML <script> tag and inside the <head> tag.

jQuery CDN

Without downloading and hosting jQuery in our environment, you can use various content delivery networks known as CDN.

Google CDN:
<head>
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js”></script>
</head>
Microsoft CDN:
<head>
<script src=”https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.3.1.min.js”></script>
</head>
jQuery CDN:
<head>
<script src=”https://code.jquery.com/jquery-3.3.1.min.js”></script>
</head>
It is always advised and recommended to learn basic web designing as HTML, CSS and JavaScript first before starting to learn jQuery.

Editors for jQuery

Before starting with its necessary to know what are the rich text editors where you can write your jQuery code. Below are some of the common editors, you can use to write jQuery code.

  • Notepad
  • Notepad++
  • Visual Studio
  • Visual Studio Code
  • CKEditor
  • TinyMCE
  • Summernote
  • Trumbowyg
  • Simditor

How to start with jQuery

As discussed above you can select any editors to write the code. You can put any number of scripts inside an HTML document, or else you can write all your jQuery code in an external file, save it with .js file extension and call that file inside our HTML Code. It is recommended not to write all jQuery code inside the HTML file as the file. In a HTML file jQuery code are written inside <script> and </script> tags.

Here we will start with a small example how to show an alert message using a button. Using above both ways:

Putting script inside HTML document

<!DOCTYPE html>

<html>

<head>

<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js”></script>

<script>

$(document).ready(function(){

$(“#btnDemo”).click(function(){

alert(“Welcome to Top 51 jQuery Examples”)

});

});

</script>

</head>

<body>

<input type = “button” id= “btnDemo” value=”Click to Download”/>

</body>

</html>

Using two separate files and calling jQuery in a HTML file

Below code is stored in an external .js file named as (51jQueryExamples.js)

$(document).ready(function(){

$(“#btnDemo”).click(function(){

alert(“Welcome to Top 51 jQuery Examples”)

});

});

And then in the HTML file we can call the above js using reference as:

<!DOCTYPE html>

<html>

<head>

<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js”></script>

<script scr=”51jQueryExamples.js”>
