Create a method from a string in JS

Question

So I have a string "getNumber":

I would like to use this string as a method for an object: myObj.getNumber()

Is that possible? Thanks

Answer 1

As simple as:

myObj['getNumber']();

Answer 2

There two ways to access value from js object .. one is dot notation . and other is square bracket notation [], which allows access to properties containing special characters and selection of properties using variables.

var key = 'getNumber';
myObj[key]();
