setAttribute and getElementById

When I do this:

col = document.createElement("div");
col.setAttribute("id", "col" + ii);
alert(document.getElementById("col" + ii));

alert displays null. How can I get setAttribute to have an effect?

When you create an element with document.createElement, it creates the element but does not add it to the DOM. To add it to DOM you have to use appendChild method on the element inside which you want your new element to be.

Let us assume that you want to add your new div at end of the body. Try the following code.

col = document.createElement("div");
col.setAttribute("id", "col" + ii);
document.body.appendChild(col)
alert(document.getElementById("col" + ii));
