Elements in an array?

[habman]

I have the following array setup

function Franchise (id, name) {
   this.id = id;
   this.name = name;
}
 
var franchiseDatabase = new Array();
franchiseDatabase['fid_0000'] = new Franchise('0000', 'Team 0');
franchiseDatabase['fid_0001'] = new Franchise('0001', 'Team 1');
franchiseDatabase['fid_0002'] = new Franchise('0002', 'Team 2');
franchiseDatabase['fid_0003'] = new Franchise('0003', 'Team 3');

I need to figure out the number of elements in franchiseDatabase


alert(franchiseDatabase.length) returns 0 when I thought it should return 4.



What is the proper way to count the # elements for franchiseDatabase if the array is set up like I have above?

Confusing as it is you have an associative arrays which is not an array at all, they are just complex objects. That means you have no length property to work with. Only way to know how many you have is to loop through it and count.

var cnt = 0;
for(var x in franchiseDatabase)cnt++;

Thank you very much.

:-)

function Franchise (id, name) {
   this.id = id;
   this.name = name;
}
function AddRec (id, name) {
   franchiseDatabase['fid_'+id] = new Franchise(id, name);
   franchiseDatabase.length++;
   alert(franchiseDatabase.length);
}

 
var franchiseDatabase = new Array();
AddRec('0000', 'Team 0');
AddRec('0001', 'Team 1');
AddRec('0002', 'Team 2');
AddRec('0003', 'Team 3');
