Call a method using a variable containing the method name

Question

I'm trying to declare a click handler using an array of strings which contains the selectors and corresponding methods to call:

['start','clear','stop','plus','minus'].forEach(function(el) {
    $("#" + el).click(function() { 
        Timer.el();     
    });
});

The point is to change Timer."array[index]"();. I tried el but the console shows an error.

To programmatically call a method of an object you need to use bracket notation. Try this:

['start','clear','stop','plus','minus'].forEach(function(el) {
    $("#" + el).click(function() { 
        Timer[el](); 
    });
});
