Print Hello World with jQuery

We already learned how to pop up a message box with jQuery when visitors open a web page. In this post, I am going to do something a little bit difficult with jQuery, but more interesting. Actually this is the most basic example of jQuery. Like other computer programming languages, let’s see how to print out the “Hello World!” greeting words with jQuery.

Add the following line of codes to the registered ready event:

// Declare a variable
var printText = “Hello World”;

// Display message on text field

You may ask “What is the .outputText?”

This is actually an element (e.g. class, <p>, <DIV>, etc..) layout on the web page contents.

Everything should be clear after seeing the HTML structure of the whole web page:

    <script type="text/javascript" src="jquery.js"></script>

    <script type="text/javascript">

        jQuery("document").ready(function() {

                // Declare a variable
                var printText = "Hello World";

                // Display message on text field


    <h1>Learning jQuery</h1>
    The printed text is: <span class="outputText">Print Here!</span>

The following diagram explain the whole process:

When you open the web page , you should see the “Hello World” appear inside the outputText span area:


The printed text is: Print Here!
