iterate through a map in javascript

Question

I have a structure like this:

var myMap = {
    partnr1: [\'modelA\', \'modelB\', \'modelC\'],
    partnr2: [\'modelA\', \'modelB\', \'modelC\']
};

Answer 1

The callback to $.each() is passed the property name and the value, in that order. You're therefore trying to iterate over the property names in the inner call to $.each(). I think you want:

$.each(myMap, function (i, val) {
  $.each(val, function(innerKey, innerValue) {
    // ...
  });
});

In the inner loop, given an object like your map, the values are arrays. That's OK, but note that the "innerKey" values will all be numbers.

edit — Now once that's straightened out, here's the next problem:

    setTimeout(function () {

      // ...

    }, i * 6000);

The first time through that loop, "i" will be the string "partnr1". Thus, that multiplication attempt will result in a NaN. You can keep an external counter to keep track of the property count of the outer map:

var pcount = 1;
$.each(myMap, function(i, val) {
  $.each(val, function(innerKey, innerValue) {
    setTimeout(function() {
      // ...
    }, pcount++ * 6000);
  });
});
