Hi biswa2ray,

Here's a simple sample vanilla javascript and jQuery I created on how to add, delete and view the values of a dynamic input elements.
You can review the sample on this link:
JSFiddle Vanilla JS Sample
JSFiddle jQuery Sample

Here's also the code:
VANILLA

//get the form element
var myForm =  document.getElementById("myForm"),
    //gets the div-container of the inputs
    ctrlGroup = document.getElementById("ctrl-group"),
    //get the add button
    addButton = document.getElementById("addInput"),
    //get the delete button
    deleteButton = document.getElementById("deleteInput"),
    //get the show value button
    showButton = document.getElementById("showVal");

// adds a new input when "add new input" button is clicked
addButton.onclick = function(){
    var newInput = document.createElement("div");
    newInput.setAttribute("name","myInput");
    newInput.innerHTML = '<label>Input ' + (ctrlGroup.childElementCount + 1) + '</label><input type="text" name="myInputA" /><input type="text" name="myInputB" /><input type="text" name="myInputC" />';
    ctrlGroup.appendChild(newInput);
};

//delete the last input when "delete input" is clicked
deleteButton.onclick = function(){
    ctrlGroup.removeChild(ctrlGroup.lastElementChild);
};

//show the value of the elements when clicked
showButton.onclick = function(){
    var inputA = document.getElementsByName("myInputA"),
        inputB = document.getElementsByName("myInputB"),
        inputC = document.getElementsByName("myInputC"),
        inputStr = "",
        i=0,
        len=ctrlGroup.childElementCount;
    for(;i<len;i++){
        inputStr += ("INPUT" + i +": " + inputA[i].value + " " + inputB[i].value + " " + inputC[i].value + "\n");
    }
    alert(inputStr);
};

JQUERY

$(document).ready(function(){
    // adds a new input when "add new input" button is clicked
    $("#addInput").on("click",function(){
        var $container = $("#ctrl-group"),
            len = $container.children().length,
            $newInput = $('<div name="myInput"><label>Input ' + (len + 1) + '</label><input type="text" name="myInputA" /><input type="text" name="myInputB" /><input type="text" name="myInputC" />');
        $("#ctrl-group").append($newInput);
    });

    //delete the last input when "delete input" is clicked
    $("#deleteInput").on("click",function(){
        $("#ctrl-group div:last-child").remove();
    });

    //show the value of the elements when clicked
    $("#showVal").on("click",function(){
        var inputVal = "";
        $("div[name=myInput]").each(function(){
            var buff="",
                $this = $(this);
            $this.children("input").each(function(){
                buff+= (this.value + " ");
            });
            inputVal += ($this.children("label").text() + ": " + buff + "\n");
        });
        alert(inputVal);
    });
});

Please let me know if you need claifications.
Also, please take note that live has been removed in the new version of jQuery. I'd suggest to use "on" instead.

@gon1387! thanks..

Hi Biswa2ray,

Here's a tweaked one from you code and js script. JS Fiddle Tweaked
I rearranged the code and structure to suit it to what assume is your want. Just add the event on the button.

Hi gon1387,
I want the rightside of button "Remove" which is creating with new line. it should be delete the same rows...
I have modified the code...

hi Biswa2ray,

I think it would be better with this:

insertRow can be used with tbody and table, and will accept an argument as the position where it should be inserted, it's the same as insertCell on a Table Row element. Both returns the inserted element, so you can modify them as you please. Those returned element can be modified like any other HTML element.

var table = document.createElement("table"),
    row1,
    cell1,
    insertedCell;

//create a new row
row1 = table.insertRow();
/***************************************
//at this point table should look like this
<table>
    <tr></tr>
</table>
***************************************/

//create a new cell at row1
cell1 = row1.insertCell();
/***************************************
//at this point table should look like this
<table>
    <tr>
        <td></td>
    </tr>
</table>
***************************************/

//create new cells for insertion sample
row1.insertCell();
row1.insertCell();
/***************************************
//at this point table should look like this
<table>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
</table>
***************************************/

//insert the a new cell at the second td position
// it's a zero index so the 2nd position is in 1
insertedCell = row1.insertCell(1);
insertedCell.innerHTML = "Hi! I'm at the 2nd position.";
/***************************************
//at this point table should look like this
<table>
    <tr>
        <td></td>
        <td>Hi! I'm at the 2nd position.</td>
        <td></td>
        <td></td>
    </tr>
</table>
***************************************/
