hi try this

var objSeatNo = <pre lang="xml">document.getElementById(&#39;&lt;%=txtSeatNo.ClientID %&gt;&#39;);

change the above line to

var objSeatNo = document.getElementById("txtSeatNo").val();

you can get the value of txtSeatNo to ObjSeatNo.

indx is the selected index no of datalist which i saved on a lable

XML

var clienttype = document.getElementById('<%=lblDivlastIndx_Itm.ClientID %>').value;
var indx = parseInt(clienttype);
indx=indx+1;

$("#ctl00_ContentPlaceHolder1_dlRouts_ctl0"+indx+"_txtSeatNo").val('New Value');

Now its working fine.
