Change div content with jQuery

This is a quick tutorial for understanding the basics of jQuery.

Create a new HTML file with this code:

<html>
<head>
<title>jQuery test page</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
// javascript here (jQuery)
</script>
</head>
<body>
<--- HTML content here -->
</body>
</html>

Right now, the page will just load the jQuery library.

Lets get some HTML content first

<a id="changeText">Change my text</a>
<br />
<div id="textBox">This text will be changed to something else</div>

jQuery code
Now we will add some javascript so that the content of 'textBox' element changes to something else once you click on 'Change my text' link.

$(document).ready(function() {
$("#changeText").click(function() {
$("#textBox").html("My text is changed!");
});
});

As soon as your page is loaded in your browser, a function is declared so that whenever you click on the link (with 'changeText' id), the content of the 'textBox' element will be changed to 'My text is changed!'.

Final output:

<html>
<head>
<title>jQuery test page</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#changeText").click(function() {
$("#textBox").html("My text is changed!");
});
});
</script>
</head>
<body>
<a id="changeText">Change my text</a>
<br />
<div id="textBox">This text will be changed to something else</div>
</body>
</html>
