Instead of removing and appending, use replaceChild().

Also, IDs cannot be only numbers. Use a letter/underscore to begin an id.

Hi,

I tried to use what you suggest but I still have a problem, it does't do anything can you take a look at it. Please look at the moveLeft and moveRight function and tell what is wrong.

Can you tell me what is wrong I can not find the problem.

A useful tool is Firebug (Firefox extension).

Acoder,

I updated the moveright function but for some reason it give me an error that I don't understand from where it comes: The idea is to create a cyclic behaviour in which each time we make shift to right i.e

A[0]-> A[1] -> A[2] -> ... A[n-1] -> A[N]-> A[0]

Expand|Select|Wrap|Line Numbers

 
// last_number_of_elements = is the number of the element in the list

// The list come in the format: x:x:x;y:y:y; .....

function moveRight()

{

      var ContainerElement=document.getElementById('ImageContainer');

       for (i=0;i<=last_number_of_elements-2;i++) {

         if (i==0) {

           ContainerElement.replaceChild(TDElement[i],TDElement[i+1]) ;

         } else {

          var shiftRight=ContainerElement.cloneNode(TDElement[i+1]);

           ContainerElement.replaceChild(TDElement[i],TDElement[i+1]) ;  

         }      

       }

     ContainerElement.replaceChild(shiftRight,TDElement[0]) ;

     setStyles(); setIDs();attachEventhandlers();

}

Thanks, acoder you are the man. In the meanwhile I rewrite the code both the next and previous function and evrything is working fine now.
