jQuery: display result in text box
<p>I have the following code:</p>

<p><a href="http://jsfiddle.net/uRCL2/1" rel="nofollow">http://jsfiddle.net/uRCL2/1</a></p>

<p>At the moment the result is shown in two span tags, what do I need change to join the two and show as a value in the text box with the <code>id=sku</code>?</p>

<hr>

<p>JS:</p>

<pre><code> $("#options").change(function(){
 switch($(this).val()){
    case "3370":
         $(".display_text_here").text('TB');
    break;
    case "3371":
         $(".display_text_here").text('LT');
    break;
    case "3375":
         $(".display_text_here").text('LTR');
    break;
    case "3372":
          $(".display_text_here").text('BO');
    break;
    case "3373":
         $(".display_text_here").text('MC');
    break;
    case "3374":
         $(".display_text_here").text('NC');
    break;
    case "3376":
          $(".display_text_here").text('STA');
    break;

  }
 });
 $("#options2").change(function(){
  switch($(this).val()){
    case "3423":
          $(".display_text_here2").text('12');
    break;
    case "3424":
         $(".display_text_here2").text('24');
    break;
    case "3425":
         $(".display_text_here2").text('48');
    break;

 }
 });
</code></pre>
