Well i tried it but it doesn't work i had to do like this.


function reOrderArr(t) {
    arr[t].nodelinks = arr[arr.length - 1].nodelinks;
    arr[t].hold = arr[arr.length - 1].hold;
    arr[t].rposX = arr[arr.length - 1].rposX;
    arr[t].rposY = arr[arr.length - 1].rposY;
    arr[t].rwidth = arr[arr.length - 1].rwidth;
    arr[t].rheigth = arr[arr.length - 1].rheigth;
    arr[t].rcolor = arr[arr.length - 1].rcolor;
    arr[t].bcolor = arr[arr.length - 1].bcolor;
    arr[t].print = arr[arr.length - 1].print;
    last=arr.length-1;
    arr.pop();
    for (var s=0;s<arr.length;s++){
      for (var v=0;v<arr[s].nodelinks.length;v++){
        if (arr[s].nodelinks[v]==last) arr[s].nodelinks[v]=t;
      }
    }
}
