Programming HTML and JavaScript in AIR
Creating an object using the name of the class as a string parameter
Adobe AIR 1.0 and later
Consider a hypothetical JavaScript class defined with the following code:
var CustomClass =
{
Utils:
{
Parser: function(){ alert('constructor') }
},
Data:
{
}
};
var constructorClassName = "CustomClass.Utils.Parser";
The simplest way to create a instance would be to use eval():
var myObj;
eval('myObj=new ' + constructorClassName +'()')
However, you could avoid the call to eval() by parsing each component of the class name and building the new object
using bracket notation:
function getter(str)
{
var obj = window;
var names = str.split('.');
for(var i=0;i
