For the moment I wrote this function that converts a plain object like
{a.b:1,a.c:2,a.d.b:3} into {a:{b:1,c:2,d:{b:3}}
function plainToNestedObject(plain){
var result = {};
$tw.utils.each(plain,
function(value,key){
createChilds(result,key.split('.'),value)
});
return result;
function createChilds(ob,keys,value){
keys = keys.slice(); // no side effects please
var lastKey = keys.pop(); //pop is handy but mutates the array
var lastChild = keys.reduce(
function(ob,k){
ob[k] = ob[k] || {};
return ob[k];
}
,ob);
lastChild[lastKey] = value;
return ob;
}
}
