in above html table, want itterate rows .questiondiv each row , .subquestiondiv each .questiondiv jquery. have written following jquery code this. getting .questiondiv row, not getting how .subquestiondiv .questiondiv object. please in this.

jquery code:

    $('#qustiontbl').find('tr').each(function (i, el) {             question={}             subquestionlist=[]              var $tds = $(this).find('td')             questiondivobj = $tds.eq(1).find('.questiondiv')             questiontxt=$(questiondivobj).find('.questiontxt').val()             question['question']=questiontxt;               // here problem, how .subquestiondiv div              // questiondivobj             $(".subquestiondiv").each( function() {                 subquestiontxt=$(this).find('.subquestiontxt').val()                 subquestionlist.push({'subquestion':subquestiontxt});             });             question['subquestions']=subquestionlist             questionslist.push(question)       }); });

you need add "context" jquery selector:

$(".subquestiondiv", questiondivobj).each(...)

in context of code:

$('#qustiontbl').find('tr').each(function (i, el) {         question={}         subquestionlist=[]          var $tds = $(this).find('td')         questiondivobj = $tds.eq(1).find('.questiondiv')         questiontxt=$(questiondivobj).find('.questiontxt').val()         question['question']=questiontxt;          // add context selector, finds within question div            $(".subquestiondiv", questiondivobj).each( function() {             subquestiontxt=$(this).find('.subquestiontxt').val()             subquestionlist.push({'subquestion':subquestiontxt});         });         question['subquestions']=subquestionlist         questionslist.push(question)   });
