javascript - jquery autocomplete: add extra parameter -

so have dropdown called category, , table 2 columns language , name.

category determine scope (books, magazines, etc.) language dropdown fixed list of values (english, spanish, etc.)

now need values of name autocompleted source scoped both global category, row's language

<tr>     <td>         <select name="row.language"></select>     </td>     <td>         <textarea name="row.name"></textarea>     </td> <tr> 

what have tried far:

$('select[name="row.language"]').change(function () {     getnameautocomplete($(this).parent().parent()); });  function getnameautocomplete(row) {     var lang = $(row).find("select[name='row.language']").val();     console.log("outer: lang = " + lang);     $(row).find('textarea[name="row.name"]').autocomplete({         source: function (request, callback) {             var cat = $("#ddlcategory").val();             console.log("inner: lang = " + lang);             encodeddata = { category: cat, language: lang, term: request.term };             $.ajax({                 type: "post",                 url: getnameautocompletelistactionurl,                 datatype: 'json',                 data: encodeddata,                 beforesend: function (jqxhr, settings) {                     $("#loadinganim").show();                 },                 complete: function (jqxhr, textstatus) {                     $("#loadinganim").hide();                 },                 success: function (data, textstatus, jqxhr) {                     callback(data);                 },                 error: function (jqxhr, textstatus, errorthrown) {                     callback();                 }             });         }      }); } 

as may have noticed, doesn't work. inner lang null, whereas outer lang has correct selected value.

appreciate if guys can give me advice how achieve this.

added jsfiddle http://jsfiddle.net/harryt/mdktg4mt/1/

and strange enough, works on jsfiddle! although if closely, jsfiddle url above, lang not defined (black instead of blue color) inside source: function (request, callback)
