Calling javascript function with an objectstring in dot notation

Question

Suppose I have the string:

var string = \"function\";

With

window[string];

I can call a function with the nam

Answer 1

you can split the string across . by using the String.split method:

var string2 = "function.method.weHaveTogoDeeper";
var methods = string2.split(".");

In this examples, methods will be the array ["function","method","weHaveTogoDeeper"]. You should now be able to do a simple iteration over this array, calling each function on the result of the previous one.

Edit

The iteration I had in mind was something like this:

var result = window;
for(var i in methods) {
    result = result[methods[i]];
}

In your example, result should now hold the same output as

window["function"]["method"]["weHaveTogoDeeper"]
