Check this Demo

</div>

window.onload=function(){
    var output = document.getElementById('output');
    var i=1;
    var val="";
    while(i<=3)
    {

        if(!document.getElementById('timedrpact'+i))
        {
            var ele = document.createElement("div");
            ele.setAttribute("id","timedrpact"+i);
            ele.setAttribute("class","inner");
            ele.innerHTML="hi "+i;
            output.appendChild(ele);

        }
        i++;


    }
};

Answer 2

Syntax for dynamic create div:

  DivId =  document.createElement('div');
  DivId.innerHtml ="text"

Answer 3

Look at document.createElement() and element.appendChild().

var newdiv = document.createElement("div");
newdiv.innerHTML = val;
document.getElementById("showselecteditems").appendChild(newdiv);

Because you will likely encounter this in the near future: You can remove any element with this code:

element.parentNode.removeChild(element);

Answer 4

Using createElement:

function selecteditems() {
  var container = document.getElementById('showselecteditems');
  for (var i=1;i<=53;i++) {
    var fld = document.getElementById('timedrpact'+i);
    if (fld) {
      var div = document.createElement("div");
      div.appendChild(document.createTextNode(fld.value));
      container.appendChild(div);
    }
  }
}

Full version using cloneNode (faster) and eventBubbling

Live Demo

var div = document.createElement("div");
var lnk = document.createElement("a");
var img = document.createElement("img")
img.className="remove";
img.src = "https://uperform.sc.gov/ucontent/e14c3ba6e4e34d5e95953e6d16c30352_en-US/wi/xhtml/static/noteicon_7.png";
lnk.appendChild(img);
div.appendChild(lnk);
function getInputs() {
  var container = document.getElementById('showselecteditems');
  for (var i=1;i<=5;i++) {
    var fld = document.getElementById('timedrpact'+i);
    if (fld) {
      var newDiv = div.cloneNode(true);
      newDiv.getElementsByTagName("a")[0].appendChild(document.createTextNode(fld.value));
      container.appendChild(newDiv);
    }
  }
}    
window.onload=function() {
  document.getElementById('showselecteditems').onclick = function(e) {
    e=e||event; 
    var target = e.target||e.srcElement; 
    // target is the element that has been clicked
    if (target && target.className=='remove') {
      parentDiv = target.parentNode.parentNode;
      parentDiv.parentNode.removeChild(parentDiv);
      return false; // stop event from bubbling elsewhere
    }
  }    
  getInputs();  
}
