Hi
I tried a simple javascript example on the w3school (http://
www.w3schools.com/JS/js_loop_for_in.asp), and the example works fine
if I don't include scriptaculous or prototype, but once I do I keep
getting a strange error.
Anyone know why this error/bug shows up, or have I done something very
strange in my code ?
Thanks for any help... examples below...
The normal example:
<html>
<body>
<script type="text/javascript">
var x;
var mycars = new Array();
mycars[0] = "Saab";
mycars[1] = "Volvo";
mycars[2] = "BMW";
for (x in mycars)
{
document.write(mycars[x] + "<br />");
}
</script>
</body>
</html>
Output of this one is:
Saab
Volvo
BMW
The modified example including the library:
<html>
<head>
<script src="javascript/prototype.js" type="text/javascript"></script>
<script src="javascript/scriptaculous.js" type="text/javascript"></
script>
</head>
<body>
<script type="text/javascript">
var x;
var mycars = Array();
mycars[0] = "Saab";
mycars[1] = "Volvo";
mycars[2] = "BMW";
for (x in mycars)
{
document.write(mycars[x] + "<br />");
}
</script>
</body>
</html>
Output of this one is:
Saab
Volvo
BMW
