Parsing JSON Object in jQuery and create drop downs -


i want parse json object , create drop downs out of it. there 6 drop downs -

producttype reportnames startdate startmonth enddate endmonth

i able create first drop down 'producttype' when trying create others shows me undefined error message.

here code -

html

  <select id="product_type"></select>   <select id="report_type"></select>   <select id="startdate"></select>   <select id="startmonth"></select>   <select id="enddate"></select>   <select id="endmonth"></select>

javascript

  var jsonstring = '[{"producttype": "abc","reportnames": ["report1",{"startdate": ["2010","2011"],"startmonth": ["may","june"],"enddate":["2010","2011"],"endmonth": ["may","june"]},"report 2",{"startdate": ["2010","2011"],"startmonth": ["may","june"],"enddate": ["2010","2011"],"endmonth": ["may","june"]}]},{"producttype": "xyz","reportnames": ["report 3",{"startdate": ["2010","2011"],"startmonth": ["may","june"],"enddate": ["2010","2011"],"endmonth": ["may","june"] },"report 4",{"startdate": ["2010","2011"], "startmonth": ["may", "june" ],"enddate": ["2010","2011"],"endmonth": ["may","june"]}]}]';      var mydata = json.parse(jsonstring);    var $product_type = $('#product_type');   var $report_type = $('#report_type');    $.each(mydata, function () {       $('<option>' + this.producttype + '</option>').appendto($product_type);   });    $.each(mydata, function () {       $('<option>' + this.producttype[0].reportnames +   '</option>').appendto($report_type);

});

basically want create 6 drop downs this:

producttype - abc, xyz

reportnames - report1, report2

startdate - 2010, 2011

startmonth - may, june

enddate - 2010, 2011

endmonth - may, june

i using jquery parse json object. here demo - http://jsfiddle.net/lnv9d/3/

you accessing json incorrectly second dropdown.

this.producttype string, not array, cannot call this.producttype[0].reportnames

if change this.reportnames[0] may looking for.

here updated jsfiddle

edit: here new fiddle handles showing , hiding options based on selected. use optimization, works.
