javascript - Drag and copy with a swap function -


i have created user interface has working drag , copy in javascript. problem div getting copied has hidden div need swap once reach dropzone. upon dragging visible div gets new id hidden 1 doesn't , when swap them swaps hidden div in it's original position. here javascript code:

these work drag , copy functions.

  function allowdrop(ev) {       /* default handling not allow dropping elements. */       /* here allow preventing default behaviour. */       ev.preventdefault();     }      function drag(ev) {       /* here specified should dragged. */       /* data dropped @ place mouse button released */       /* here, want drag element itself, set it's id. */       ev.datatransfer.setdata("text/html", ev.target.id);     }      function drop(ev) {       ev.preventdefault();       var data=ev.datatransfer.getdata("text/html");       /* if use dom manipulation functions, default behaviour not          copy alter , move elements. appending ".clonenode(true)",          not move original element, create copy. */       var nodecopy = document.getelementbyid(data).clonenode(true);       nodecopy.id = "newid"; /* cannot use same id */       ev.target.appendchild(nodecopy);     }     </script> function works divs swap      <script type="text/javascript"> function swapdivswithclick(div1,div2) {  d1 = document.getelementbyid(div1);  d2 = document.getelementbyid(div2);  if( d2.style.display == "none" )  {     d1.style.display = "none";     d2.style.display = "block";  }  else  {     d1.style.display = "block";     d2.style.display = "none";  } } </script>

is there way drag hidden div along visible one? can hidden div assigned new number can swapped?

thank you

i managed solve little riddle. divs swap when dragged drop zone there's no need have them swap on mouse click. anyway here javascript functions used, had modify drag , copy previous 1 posted. 

<script>  function allowdrop(ev) {  ev.preventdefault();  }   function drag(ev) {  ev.datatransfer.setdata("text",ev.target.id);  }   function drop(ev) {  ev.preventdefault();  var data=ev.datatransfer.getdata("text");  ev.target.appendchild(document.getelementbyid(data).clonenode(true));  }  </script>  {{--works swap functions--}}  <script type="text/javascript">  function swapdivswithclick(div1,div2)  {  d1 = document.getelementbyid(div1);  d2 = document.getelementbyid(div2);  if( d2.style.display == "none" )  {  d1.style.display = "none";  d2.style.display = "block";  }  else  {  d1.style.display = "block";  d2.style.display = "none";  }  }  </script>

here 1 set of components incase helps else:

<div id="swapper-two" style="display:none; padding:0px;">  <table align="center" border="0" cellpadding="0" cellspacing="0" width="600px" draggable="true" ondragstart="drag(event)" id="drag1">  <tr>  <td align="left" bgcolor="40374b" style="padding: 0px 0px 0px 60px;">  <a href="" style="font-family:helvetica neue"><img src="" valign="top" alt="" draggable="false" color: #ffffff; font-family: helvetica neue, helvetica, arial, sans-serif"</a>  <td style="color:#ffffff; padding:0px 60px 5px 0px; font-family: helvetica neue, helvetica, arial, sans-serif; font-size: 12px;" bgcolor="40374b" align="right" valign="bottom">  <p><a href="" span style="text-decoration: none; color: #ffffff; font-family: helvetica neue, helvetica, arial, sans-serif" >login&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp</a><a href="" style="text-decoration: none; color: #ffffff; font-family: helvetica neue, helvetica, arial, sans-serif">my account</a></p>  </td>  </tr>  </table>  </div>  <div class="img" draggable="true" ondragstart="drag(event)" id="drag9">  <div id="swapper-one" style="display:block; padding:0px;" >  <table align="center" border="0" cellpadding="0" cellspacing="0" bgcolor="" draggable="true" ondragstart="drag(event)" id="drag1">  <tr>  <td align="center">  <img src="" draggable="false" alt="" width="610" height="270" id="img-one" />  </td>  </tr>  </table>  </div>  </div>
