Hey All,
I need some help with my javascript program. I need to write a program that diplays an image, and when clicked, it changes to a different image. And when you click on the 2nd image, it changes back to the 1st, and so on. I got the program to switch to the 2nd image, but can't get it to switch back. My instructor gave us a hint that we have to use string comparison? I've looked all through the book and w3schools, but can't find anything. Please help! What piece of code am I missing? Here's what I have so far:
<html>
<head>
<title>Javascript Assignment 4 Part 3</title>
<script language = "Javascript">
// Blue Jacket:
http://www.newenough.com/product_pic...blue_front.jpg
// Red Jacket:
http://www.newenough.com/product_pic.../red_front.jpg
//The function is called when the image in the body is clicked.
//The function changes the image source of 'Blue Jacket' to 'Red jacket'
function rollover ()
{
document.picture.src = "http://www.newenough.com/product_pictures/a/alpinestars_tz1_jacket/red_front.jpg";
}
</script>
</head>
<body>
<h1>Welcome to Switching Images!</h1>
<!-- there is an image tag below with the name picture that displays 'Blue Jacket'.
When the image is clicked, the 'rollOver()' function is called -->
</body>
</html>
Javascript string comparison?
