issue with undefined var in javascript, jquery. how to?

I am using Date.js to display some dates and a weird thing happens. If I use it in an array formed from within an each statement.

Here is what i mean:

If I pass and use the events_array to the test function array everything works fine, but if I use the eventsArray one, that should look the same, I get:

startDate is undefined
...new Date(startDate.getFullYear(), startDate.getMonth(), startDate.getDate()).getTime()...

function getTest() {
    $.ajax({
        type: "GET",
        url: "/index",
        dataType: "json",
        success: function (data) {

            var eventsArray = new Array();

            jQuery.each(data, function (i, val) {

                eventsArray.push(
                new Array({
                    startDate: new Date(2011, 07, 20, 15, 50),
                    endDate: new Date(2012, 00, 10),
                }));
            });

            var events_array = new Array({
                startDate: new Date(2011, 07, 20, 15, 50),
                endDate: new Date(2012, 00, 10),
            }, {
                startDate: new Date(2011, 07, 20, 15, 50),
                endDate: new Date(2012, 00, 10),
            });

          test(events_array);

        }
    });
}

Any ideas?

Thanks

your two arrays are not identicals : var eventsArray = new Array();

        jQuery.each(data, function (i, val) {

            eventsArray.push(
            new Array({
                startDate: new Date(2011, 07, 20, 15, 50),
                endDate: new Date(2012, 00, 10),
            }));
        });
        /* here eventsArray is like that [[{
                startDate: new Date(2011, 07, 20, 15, 50),
                endDate: new Date(2012, 00, 10),
            }]] Look at the two [[ or ]] : array of object in an array
         */
        var events_array = new Array({
            startDate: new Date(2011, 07, 20, 15, 50),
            endDate: new Date(2012, 00, 10),
        }, {
            startDate: new Date(2011, 07, 20, 15, 50),
            endDate: new Date(2012, 00, 10),
        });
        /* here events_array is like that [{
                startDate: new Date(2011, 07, 20, 15, 50),
                endDate: new Date(2012, 00, 10),
            }, {}] only one [ ... array of objects ...
         */

i think you should use : 

eventsArray.push({
    startDate: new Date(2011, 07, 20, 15, 50),
    endDate: new Date(2012, 00, 10)
}); });

Hope this helps

Within your test function try following:

function test(eventsArray) {
  // try this

  eventsArray[0][0].startDate
}

eventsArray looks like following:

eventsArray = [ 
                 [
                     {
                          startDate: ..
                          endDate: ..
                     }
                 ] 
              ];

But you should make it easier:

var eventsArray = new Array();

    eventsArray.push({
     startDat: ..
     endDate: ..
    });

Don't use additional array within eventsArray if you not need it.

and to access that values use:

eventsArray[0].startDate;

eventsArra[0].endDate;

If you look at your events_array, you'll see that, you're not using additional array when you push data within it.

You probably meant to fill eventArray with objects, not arrays with a single object in each one:

eventsArray.push({ // NOT new Array...
    startDate: new Date(2011, 07, 20, 15, 50),
    endDate: new Date(2012, 00, 10)
}); });
