Array Problem

[ziycon]

I have a variable called num and i want to pass it into the array element number but i get undefined showing on the page, heres what i mean:

If i put 1 into the document.write(array[1]); then it works fine??

var num = 1;
 
array[1] = 'Test';
 
document.write(array[num]);

define array

var num = 1, array=[];
 
array[1] = 'Test';
 
alert(array[num]);

How does your "array[1]" work fine? Neither "array[1]" nor "array[num]" is working.
Array is not a primary data type, so you need to define before you use it.
