The W3schools and Codecademy have great tutorials as to how Javascript works.


A very cool way to use Java Script! (The script uses alert box function and document.write command)

Syntax Alert Box

<script type="text/javascript">
alert("Text for Alert ");

<script type="text/javascript">
alert("Welcome to CIS233");

Syntax Prompt

<script type="text/javascript">
variable declared
variable=prompt("Prompt Text"," ")

<script type="text/javascript">
var Name
Name=prompt("Please enter your name","")

Syntax Document. Write

<script type="text/javascript">
document.write("Text to Write ");

<script type="text/javascript">
document.write("Welcome to CIS233");

JavaScript is an Event Driven Language (something must trigger the script to work)

Event What it does
onclick: JavaScript starts by clicking (a link, or form boxes)
onload: JavaScript starts after the page or an image has finished loading.
onmouseover: JavaScript starts by the mouse moving over a link
onmouseout: JavaScript starts by the mouse moving off the link
onunload: JavaScript starts after you leave the page.


HTML DOM breaks the Webpage into parts that Javascript of PHP can manipulate.


is my favorite to access a specific location in an HTML Document.


We will use the onClick event to trigger opening a new window!

Syntax Pop-up Window"URL", "target","features","")"","_blank", "width=400, height=400")
Features include dimensions of the window and tool bars

We will create a link
<a href="#" onclick="'','_blank', 'width=400, height=400')">Link</a>
Make sure you notice the quotes (single vs double) plus the fact the href is #

For an external File place the call in the head : <script type="text/javascript" src="codefile.js" >

JQuery and JSON are JavaScript Libraries

JQuery, JQuery Interface and JQuery Mobile

jQuery is a library of JavaScript Functions

jQuery is a lightweight, "write less, do more", JavaScript library.

JQuery Foundation has a few tutorials and videos on how to use its open source product

W3schools has a good tutorial on JQuery

Basic syntax is: $(selector).action()

jQuery Selectors - $(CSS selectors) - to identify the elements to be manipulated

$("*") selects all elements.

$("li") selects all <li> elements.

$("h1.main") selects all <h1> elements with class="main".

$("h1#menu") selects the first <h1> elements with id="menu".

$(":animated") selects all elements that are currently animated.

$(":button") selects all <button> elements and <input> elements of type="button".

$(":even") selects even elements.

$(":odd") selects odd elements.

The Document Ready Event:

Some jQuery methods are inside a document ready event to prevent them from running before the document is finished loading (is ready):



// jQuery methods go here...




DHTML is NOT a language but a Marketing Ploy! DHTML is the mixture of HTML, Javascript, and CSS.

Final Step:

Review in your mind everything we covered in class and remember to cover it again before you go to bed so your mind to process this information while you sleep.
