Question

I’m putting some dates into an array, and would like to have a second ‘tier’ in that array hold an order number associated with that date. It appears to be working correctly, but when I print out the array in the chrome console, I only see the first array of dates. If I access manually console.log(dateArray[1]['order_number']);, I see the expected information. Have I not constructed this array properly?

Thanks!

    for ( var u in valuesArr ) {

        //store the text seperator between the information and the order it is associated with
        var sep = "?order_num=";

        //store the string from which the information and order number will be extracted
        var str = valuesArr[u];

        //location of seperator
        var start = str.indexOf("?order_num=");

        var order_number = str.substring(start+sep.length);

        var current_date = valuesArr[u].substring(0, start);

        //date goes into "current_date" array
        current_date = current_date.split(" / ");

        //fashion it into a javascript date
        //month needs one subtracted
        dateArray[u] = new Date ( current_date[2], current_date[0]-1, current_date[1]);

        /*
        *to identify from which order this date derives, an order_number slot is created
        *underneath the sorted date slot
        *this is done so that when the html is reformatted to re-order the dates
        *the content associated with this date can be 'brought along with' it
        *as the its parent div's id contains the order number
        */
        dateArray[u]['order_number'] = order_number;

    }
    console.log(dateArray)//only outputs the array of dates
    console.log(dateArray[1]['order_number']);//outputs the order number

What you are doing with dateArray[u]['order_number'] = order_number; is adding a property to the Date object, not adding an element to the array.

To add an element to the array, use:

dateArray[u][1] = order_number;
