Dynamic textbox creation

HI ,
I am trying to create text boxes dynamically , add the content of those textboxes and finally edit the column of the table.
<html>
    <head>
        <script language='javascript'>
            function getBoxes2(){
                var val=document.getElementById("initTextBoxId2").value;
                var rid=document.getElementById("boxesId2");
                var str="";
                if(isNaN(val)){
                    alert("you have entered illegal value");
                    return;
                }
                else{
                    str +="<div id='allTextBoxes'>";

                    for(var i=1;i<=val;i++)
                    {
                        str +="<div>";
                        str +="    <span>new text box "+i+ " :</span>";
                        str +="    <span><input type='text' value='' size='30' /></span>";
                        str +="</div>";
                    }
                    str +="</div>";

                    str +="<div>";
                    str +="    <span><input type='button' value='Enter'  onClick='javascript:getSum2()'/></span>";

                    str +="</div>";

                    rid.innerHTML=str;
                }
            }
            function getSum2(){
                var txtBoxes=document.getElementById("allTextBoxes").getElementsByTagName("input");
                var sum=0;
                var val;
                for(var  i=0;i<txtBoxes.length;i++){
                    val=parseInt(txtBoxes.value);
                    sum +=val;
                }

               // str+="<span><input type='text' value="sum" /></span>";
            }

First of all, I moved your post to the correct forum. You've posted a couple times now, and never in the right place. As for this particular question, you don't seem to be using Yii here at all.

Sorry for it sir. I want to implement the above task in yii. Its getting difficult for me to do it as i am learning it now.
Basically please give me idea of where to implement that in yii.
Is it in the controller or in the model class.
Also tell me the need of Modules in yii.
Please help me sir

Okay, if you want to do this dynamically, you'll need to use JavaScript in the View to do it. You'll also need to adjust the Controller and the Model to allow for an array of text boxes. In short, this is not going to be easy.

You would use modules in Yii if you have separate components to a Web site. Like I might use a module for the forums area.
