For example;
var s = "function test(){
alert(1);
}";
var fnc = aMethod(s);
If this is the string, I want a function that's called fnc. And fnc();
pops alert screen.
eval("alert(1);")
doesnt solve my problem.
A better way to create a function from a string is by using Function
:
var fn = Function("alert('hello there')");
fn();
This has as advantage / disadvantage that variables in the current scope (if not global) do not apply to the newly constructed function.
Passing arguments is possible too:
var addition = Function("a", "b", "return a + b;");
alert(addition(5, 3)); // shows '8'
