Now I have found a solution by myself (old fashion syntax):
//=====================================================
function foo() {
var fn_done, fn_each;
var ctx = {
done:function(fn) {fn_done = fn; return this;},
each:function(fn) {fn_each = fn; return this;}
}
setTimeout(function() {
var oldItems = [1,2,3,4],
newItems = oldItems.map(function(x) {return x * 2});
if (typeof fn_each == 'function') {
for (var i=0; i<oldItems.length; i++) {
fn_each(oldItems[i], newItems[i]);
}
}
if (typeof fn_done == 'function') fn_done(newItems);
}, 500);
return ctx;
}
console.log('------------------------------');
foo()
.each(function(oldItem, newItem) {
console.log('oldItem: ' + oldItem + ' ' + 'newItem: ' + newItem);
})
.done(function(result) {
console.log('------------------------------');
console.log('result: ' + result);
console.log('------------------------------');
});
//=====================================================
I am sure this can be more elegant but it seems to work.
