Question

I’m trying to copy the <options> HTML Codes from one select list to another. I have tested the script below, but it does not work.

I have tested with an ‘alert’ function, but it seems to only display the values within the previous options.

would anyone be able to recommend what I should use? Thank you!

$("select[name='NHIndexNo" + tablecounter + "_" + rowCount + "'] option").each(function(){
   $("select[name='NHIndexNo" + tablecounter + "_" + (rowCount+1) + "'] option").appendto($(this).val());
});

jQuery:

$().ready(function() {  
     $('#add').click(function() {  
        return !$('#select1 option:selected').remove().appendTo('#select2');  
     });  
     $('#remove').click(function() {  
        return !$('#select2 option:selected').remove().appendTo('#select1');  
     });  
 });

HTML:

<div>  
  <select multiple id="select1">  
   <option value="1">Option 1</option>  
   <option value="2">Option 2</option>  
   <option value="3">Option 3</option>  
   <option value="4">Option 4</option>  
  </select>  
  <a href="#" id="add">add &gt;&gt;</a>  
</div>  
<div>  
  <select multiple id="select2"></select>  
  <a href="#" id="remove">&lt;&lt; remove</a>  
</div>
