You should try like this.

var itemId = $('#<%=lblBookName.ClientID%>').val();
var itemName = $('#<%=lblPrice.ClientID%>').val();
var itemPrice =$('#<%=txtimg.ClientID%>').val();

hope it helps :)

If you are using .Net 4.0 I would recomment ClientIDMode="Predictable" to generat ID's which are easy to use with javascript.
