OLPCities/Window

From OLPC

Jump to: navigation, search

"Window" is a Class that is part of the DOM (Document Object Model). This "library" is referenced automaticaly by the browser of the OLPC station and you don't need to add anything in the program to use it.


You don't need to create any object for this Class. You will use the "prefix": window to call its elements.

Example:
<html>

<script language="Javascript">
 function init(){

 }
</script>
</head>
