JavaScript Data Manipulation Set object property given its string name
Example
function assign(obj, prop, value) {
if (typeof prop === 'string')
prop = prop.split('.');
if (prop.length > 1) {
var e = prop.shift();
assign(obj[e] =
Object.prototype.toString.call(obj[e]) === '[object Object]'
? obj[e]
: {},
prop,
value);
} else
obj[prop[0]] = value;
}
var obj = {},
propName = 'foo.bar.foobar';
assign(obj, propName, 'Value');
// obj == {
// foo : {
// bar : {
// foobar : 'Value'
// }
// }
// }
