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

Question

是否可以在JS中将函数的名称存储为字符串，并从对象中调用它，就像下面的PHP代码一样？

$this->$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.
