“Walk” JSON response and populate form fields — more efficient approach?

Question

I know there is a far more elegant/efficient way of doing this (in php I would use foreach) but with jQuery how can I walk the var/val pairs of a JSON response and populate

Answer 1

If your results looks like this:

[{"field1":"value1","field2":"value2"}]

Then the code provided by Seb and Chetan works

$.each(data, function(i, item){
  $("#"+item.field).val(item.value);
});

If your results looks like this:

{"field1":"value1","field2":"value2"}

Then use this code

$.each(data, function(field, value){
  $("#"+field).val(value);
});
