JavaScript: What is the equivalent of PHP's "$this->$somefunc()" ?

Question

Is it possible to store the name of a function as string in JS, and invoke it from an object, pretty much like the PHP code below?

$this->$someFunc();

Answer 1

this[someFunc]();

Answer 2

Sure thing. Try this:

var f = "foo";
var result = obj[f]();

where foo is a method on obj, or

this[f]();

where foo is a method on the current instance.
