Foil 31 The New Way of Defining Arrays

From JavaScript Tutorial for CPS616 Technologies of the Information Age 1997 Basic Information Track of CPS -- Spring Semester 97. by Geoffrey C. Fox * Important Information in IMAGE

Addon

Write var area = new Array(); // Introduced in Netscape 3

and then you can set as described in Netscape Press book on JavaScript

area[0] = "Alabama";

area[1] = "Alabama";

area[2] = "Alaska"; // etc.

acode[0] = 205;

acode[1] = 334;

acode[2] = 907; // mappring area codes to states

area.length is automatically set as length of array ( 3 in this case)

Note you can set array elements to be objects to make Arrays of objects

e.g. listofmenus = new Array();

listofmenus[0] = new menuobject(1,'world');

worldmenu = listofmenus[0]; // A synonym
