i have object of objects, i'd sort property... having trouble wrapping head around it:
sample = { "elem1": { title: "developer", age: 33 }, "elem2": { title: "accountant", age: 24 }, "elem3": { title: "manager", age: 53 }, "elem4": { title: "intern", age: 18} } my expected result object keys ordered elem4, elem2, elem1, elem3. alternatively, i'd fine returning keys in order rather physically sorting object.
is more trouble it's worth, or missing obvious (or not-so-obvious) javascript-fu make light work of this?
thanks!
properties (keys) of object not intrinsically ordered; must maintain own array of ordering if wish so.
here example of how simplify ordering sample object arbitrary properties via custom sort functions:
var orderkeys = function(o, f) { var os=[], ks=[], i; (i in o) { os.push([i, o[i]]); } os.sort(function(a,b){return f(a[1],b[1]);}); (i=0; i<os.length; i++) { ks.push(os[i][0]); } return ks; }; orderkeys(sample, function(a, b) { return a.age - b.age; }); // => ["elem4", "elem2", "elem1", "elem3"] orderkeys(sample, function(a, b) { return a.title.localecompare(b.title); }); // => ["elem2", "elem1", "elem4", "elem3"] once properties ordered can iterate them , retrieve corresponding values in order.
