To assign to a variable, you would use:

data[test] = someVal;

Hi

is it possible in javascript to use a value as a variable?

Could you explain this ?

Anyway, the closest would be to use [tt]eval()[/tt] :

a='b'

c='a'

alert(c) [gray]// gives 'a'[/gray]

alert(eval(c)) [gray]// gives 'b'[/gray]
