var worker_record = []; 
$(document).ready(function(){ 
    workerData(); 
    $('.worker').on('click', function(e){ 
     e.preventDefault(); 
     e.stopPropagation(); 

     var title = $('.title:first').val();    

     var someData = {title: title}; 
     worker_record.push(someData); 

     sessionStorage.worker = JSON.stringify(worker_record); 
     workerData(); 
    }); 

    function workerData(){ 
     var max_fields = 6; 
     var x = 1; 

     if(!(typeof sessionStorage.worker === 'undefined' || sessionStorage.worker.length<1)){ 
      worker_record = JSON.parse(sessionStorage.worker); 
     } 

     $('.add-more').empty(); 
     for(var i=0; i<worker_record.length; i++){ 
      if(x < max_fields){ 
       x++; 
       var title = worker_record[i].title; 

       var worker = '<div><div class="delete-worker"><a title="" href="#">Delete</a></div><select name="title[]" class="title title-options"><option value="Select a Title" selected="selected">Select a Title</option><option value="Boss">Boss</option><option value="Worker">Worker</option><option value="Manager">Manager</option></select></div>'; 

       $('.add-more').append(worker); 
       $('.title:eq('+$('.title-options').length+')').val(title); 
      } 
     } 

     $('.title:first').val('Select a Title'); 
    } 

    $('.add-more').on('click', '.delete-worker', function(e){ 
     e.preventDefault(); 
     e.stopPropagation();  

     $(this).parent('div').remove(); x--; 
    }); 
});

입니다 Sessionstorage에서 작업자 기록을 삭제하는 방법

worker_record = JSON.parse(sessionStorage.worker); 
    alert(worker_record); 
    worker_record.splice(worker_record.length -1, 1);// Record index passed as 2nd paramter 
    alert(worker_record); 
    sessionStorage.worker = JSON.stringify(worker_record);
