Question

I have tried to generate dynamic Control. It is working on FF but IE gives error:

divcntrl[i] is undefined.

Please check the following code:

 var mc=document.getElementById("maindiv");
    var divcntrl = new Array();
    for(var i=0; i<10;i++) {
      divcntrl[i]=document.createElement("div");\\error here
    divcntrl[i].setAttribute("id","div"+ i);
      mc.appendChild(divcntrl[i]);
}

There is no such thing as <div1> element. Running your code in a fiddle, it runs without errors so the problem is somewhere else. Are you cached with a bad version of the file?

var mc=document.getElementById("maindiv");
var divcntrl = new Array();
for(var i=0; i<10;i++) {
    divcntrl[i]=document.createElement("div");
    divcntrl[i].innerHTML = i;
    mc.appendChild(divcntrl[i]);
}​

I think you would want to code it more like

var mc = document.getElementById("maindiv");
var divcntrl = [];
for (var i=0; i<10; i++) {
    var div = document.createElement("div");
    div.id = "div" + i;
    div.innerHTML = i;
    divcntrl.push(div);
    mc.appendChild(div);
