Update a JavaScript object with a dotted path string. You pass the string path and the object you want.,

functions.js

// company = {}
// Use putObject("owner.name", company,"Sadjow");
// Returns {owener: {name: "Sadjow"}}

function putObject(path, object, value) {
    var modelPath = path.split(".");
 
    function fill(object, elements, depth, value) {
        var hasNext = ((depth + 1) < elements.length);
        if(depth < elements.length && hasNext) {
            if(!object.hasOwnProperty(modelPath[depth])) {
                object[modelPath[depth]] = {};
            }
            fill(object[modelPath[depth]], elements, ++depth, value);
        } else {
            object[modelPath[depth]] = value;
        }
    }
    fill(object, modelPath, 0, value);
}
