jQuery multidimensional object with multidimensional arrays

flot, jquery

Solution

Your datasets is an object, not an array - you can't push to it. Also, your variable `categoryName` does not work like that (read more on dot and bracket notation). Try this:

var datasets = {};
$('div#Container ul').each(function () {
    catName = this.id;
    var array = [];
    $('li', this).each(function () {
        array.push([
          new Date($(this).data('key')).getTime(),
          $(this).text()
        ]);
    });
    datasets[catName.toLowercase()] = {
        label: catName.toUppercase(),
        data: array
    };
});

Also, I'm not sure whether you really would need to create `Date` objects, but that depends on your in- and output format.

Problem

Im trying to build a somewhat advanced "Flot" jQuery pluging graph. For that, I need a multidimensional object (or at least I think it is). The structure should look like this: ``` var datasets = { "usa": { label: "USA", data: [[1988, 483994], [1989, 479060], [1990, 457648], [1991, 401949], [1992, 424705], [1993, 402375], [1994, 377867], [1995, 357382], [1996, 337946], [1997, 336185], [1998, 328611], [1999, 329421], [2000, 342172], [2001, 344932], [2002, 387303], [2003, 440813], [2004, 480451], [2005, 504638], [2006, 528692]] }, "russia": { label: "Russia", data: [[1988, 218000], [1989, 203000], [1990, 171000], [1992, 42500], [1993, 37600], [1994, 36600], [1995, 21700], [1996, 19200], [1997, 21300], [1998, 13600], [1999, 14000], [2000, 19100], [2001, 21300], [2002, 23600], [2003, 25100], [2004, 26100], [2005, 31100], [2006, 34700]] } }; ``` From my code-behind i've generated some lists looking like this (Not the same data, but dont mind that): ``` <ul id="MOBILISATION"> <li data-key="2012/3/27">02:10</li> <li data-key="2012/3/28">05:25</li> <li data-key="2012/3/29">09:21</li> <li data-key="2012/3/30">00:00</li> <li data-key="2012/3/31">00:00</li> </ul> <ul id="OPERATIONS"> <li data-key="2012/3/27">19:51</li> <li data-key="2012/3/28">18:35</li> <li data-key="2012/3/29">14:39</li> <li data-key="2012/3/30">07:46</li> <li data-key="2012/3/31">10:26</li> </ul> ``` Where "USA/usa" is "MOBILISATION", "1988" is "2012/3/27" and "483994" is "02:10". You get picture!!?? I've tried writing some jQuery, but it obviously doesnt work: ``` var objects = []; var array = []; var categoryName = ""; $('div#Container ul').each(function () { catName = $(this).attr('id'); $('li', this).each(function () { array.push([new Date($(this).data('key')).getTime(), $(this).text()]); }); objects.push({ categoryName: { label: categoryName, data: array} }); }); var datasets = objects; ``` As you can see i've used push to `objects` array. Clearly that is not giving me the result I want. Im kindda loosing whats up and down in this, as its the first time I'm working with jQuery objects. Whats the best solution for this?
