"Document" 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.

We are now (sept 2006) doing tests to verify all the methods and properties of this Class that is working OK with the OLPC station. So, we have only a few elements presented here.

You don't need to create any object for this Class because it will have only one stantialization for a page. You will use the "prefix": document to call its elements.

Properties


cookie [= String]              Is R/W. Used to write or read a cookie. The String is:
                               "name-of-cookie = value; expires=expiration-date"
                                An example, of code, reading the data from a textbox to a cookie "dynamic1";

                 then = new Date();
                 then.setTime(then.getTime() + 60*60*1000) //cookie available one hour
                 document.cookie = "dynamic1="+document.form1.tb1.value+";expires="+then.toGMTString(); 
                             

(object of the Class  Form)  Normaly we have a chain of objects, because a property of the 
                                Class Form can be an object of the Class   TextBox   etc.
                                By example: we can capture what was typed at a textbox  with:
                                document.form1.tb1.value
