How to set class attribute of an element in Javascript? [duplicate]

Question

Here is my code for generate combobox. How can I add a css class name 'chosen-select' on it ?

var cell3 = row.insertCell(2);    
var element2 = document.createElement("select");   

var option1 = document.createElement("option");   
option1.value="";   
option1.innerHTML="--Select--";      
element2.appendChild(option1);   

var option2 = document.createElement("option");   
option2.value="1";   
option2.innerHTML="Apple";     
element2.appendChild(option2);   

element2.name = "description" + rowno;  
element2.id = "description" + rowno;   
element2.setAttribute("required","true");   
element2.style.width = "150px";   
cell3.appendChild(element2);

You can use className property :

element2.className = "chosen-select";

It is. You must have mistaken somewhere. Where did you put this line ?

element2.name = "description" + rowno; element2.id = "description" + rowno; element2.setAttribute("required","true"); element2.style.width = "150px"; element2.className = "chosen-select"; cell3.appendChild(element2);
