So i needed a way to elegantly handle incoming requests and route them to appropriate functions. I had an object comming in with some variables – one specifying the method to execute and the other(s) containing relevant data. I could use a switch statement, but i need to keep the script as small as possible (and i want something more dynamic).
In PHP i’d use variable functions -
function sheep() {...}
$cow = "sheep";
$cow() // Executes function sheep()
JS can’t handle that. So i google’d around and found a post that was quite helpful on the subject. After a slight optimisation I’ve come to this:
function sheep() { alert("behh"); }
var test = "sheep";
window[test](); // Will execute sheep()
And now i can use variable functions in javascript
