concat string in dynamic feild : I have the following code, where partial functionality is completed. 
but what I need to do next is to concat all the feild's that the user input in this form. 

    <HTML>
    <HEAD>
    	<TITLE> Add/Remove dynamic rows in HTML table </TITLE>
    	<SCRIPT language="javascript">
    	
    		function addRow(tableID) {
    
    			var table = document.getElementById(tableID);
    
    			var rowCount = table.rows.length;
    			var row = table.insertRow(rowCount);
    
    			var cell1 = row.insertCell(0);
    			var element1 = document.createElement("input");
    			element1.type = "checkbox";
    			element1.name="chkbox[]";
    			cell1.appendChild(element1);
    
    			var cell2 = row.insertCell(1);
    			cell2.innerHTML = rowCount + 1;
    
    			var cell3 = row.insertCell(2);
    			var element2 = document.createElement("input");
    			element2.type = "text";
    			element2.name = "txtbox[]";
    			cell3.appendChild(element2);
    
    
    		}
    
    		function deleteRow(tableID) {
    			try {
    			var table = document.getElementById(tableID);
    			var rowCount = table.rows.length;
    
    			for(var i=0; i<rowCount; i++) {
    				var row = table.rows[i];
    				var chkbox = row.cells[0].childNodes[0];
    				if(null != chkbox && true == chkbox.checked) {
    					table.deleteRow(i);
    					rowCount--;
    					i--;
    				}
    
    
    			}
    			}catch(e) {
    				alert(e);
    			}
    		}
    
    	</SCRIPT>
    </HEAD>
    <BODY>
    
    	<INPUT type="button" value="Add Row" onclick="addRow('dataTable')" />
    
    	<INPUT type="button" value="Delete Row" onclick="deleteRow('dataTable')" />
    	
    	
    	<TABLE id="dataTable" width="350px" border="1">
    		<TR>
    			<TD><INPUT type="checkbox" name="chk"/></TD>
    			<TD> 1 </TD>
    			<TD> <INPUT type="text" /> </TD>
    		</TR>
    	</TABLE>
    
    </BODY>
    </HTML>

 

-> for example if the user click on add row 4 times, the form will create 4 rows now while he click some button (to be made) the result should be concatination of all the inputs in one large text area.
