Hi,
A little dummy question...
How can I create an Array from a given one ?
var array1 = new Array();
array1.push("A");
array1.push("B");
array1.push("C");
How to create array 2 from array 1 ?
var array2 = new Array(array1);
or
array2 = new Array();
array2.pushAll ???
In Java on Collection there is a method addAll()
Regards
