<script>

// Here are the initial values for our animation

var x = 0, y = 0, w=200, h=200; // Window position and size

var dx = 5, dy = 5; // Window velocity

var interval = 100; // Milliseconds between updates


// Create the window that we 're going to move around

// The javascript: URL is simply a way to display a short document

// The final argument specifies the window size

var win = window.open( 'javascript: " <h1> BOUNCE! </h1> " ', " ",

"width= " + w + ",height= " + h);


// Set the initial position of the window

win.moveTo(x,y);


// Use setInterval( ) to call the bounce( ) method every interval

// milliseconds. Store the return value so that we can stop the

// animation by passing it to clearInterval( ).

var intervalID = window.setInterval( "bounce( ) ", interval);


// This function moves the window by (dx, dy) every interval ms

// It bounces whenever the window reaches the edge of the screen

function bounce( ) {

// If the user closed the window, stop the animation

if (win.closed) {

// Bounce if we have reached the right or left edge

// Update the current position of the window

// Finally, move the window to the new position

<!-- Clicking this button stops the animation! -->
