hi,plz send me the code for me using search button bind the data from data base in dropdownlist
Here is a jsp code that allow the user to search the particular employee details by selecting name of the employee.
1)selectname.jsp:
<%@page import="java.sql.*"%> <html> <head> <script type="text/javascript"> function showEmp(emp_value){ if(document.getElementById("address").value!="-1"){ xmlHttp=GetXmlHttpObject() if (xmlHttp==null){ alert ("Browser does not support HTTP Request") return } var url="getvalue.jsp" url=url+"?name="+emp_value xmlHttp.onreadystatechange=stateChanged xmlHttp.open("GET",url,true) xmlHttp.send(null) } else{ alert("Please Select Employee Id"); } } function stateChanged(){ document.getElementById("email").value =""; document.getElementById("address").value =""; if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete") { var showdata = xmlHttp.responseText; var strar = showdata.split(":"); if(strar.length==1){ document.getElementById("address").focus(); alert("Please Select Employee Id"); document.getElementById("email").value =" "; document.getElementById("address").value =" "; } else if(strar.length>1) { var strname = strar[1]; document.getElementById("address").value= strar[1]; document.getElementById("email").value= strar[2]; } } } function GetXmlHttpObject(){ var xmlHttp=null; try{ xmlHttp=new XMLHttpRequest(); } catch (e) { try { xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; } </script> </head> <body> <form name="employee"> <br><br> <table border="0" width="400px" align="center" bgcolor="#CDFFFF"> <div id="mydiv"></div> <tr><td><b>Select Employee Name to Search</b></td><td> <select name="name" onchange="showEmp(this.value);"> <option value="-1">Select</option> <% Class.forName("com.mysql.jdbc.Driver").newInstance(); Connection conn = DriverManager.getConnection( "jdbc:mysql://localhost:3306/test","root","root"); String query = "select * from employee"; Statement st = conn.createStatement(); ResultSet rs = st.executeQuery(query); while(rs.next()) { %> <option value="<%=rs.getString("name")%>"><%=rs.getString("name")%></option> <% } %> </select> </td></tr> <tr><td ><b>Employee Address:</b></td><td> <input type="text" name="address" id="address" value=""></td></tr> <tr><td><b>Employee Email:</b></td><td> <input type="text" name="email" id="email" value=""></td></tr> </table> </form> <table border="0" width="100%" align="center"> <br> <br> </table> </body> </html>
2)getvalue.jsp:
<%@page import="java.sql.*"%> <% String emp_id = request.getParameter("name").toString(); String data=""; int sumcount=0; Statement st; try { Class.forName("com.mysql.jdbc.Driver").newInstance(); Connection conn = DriverManager.getConnection( "jdbc:mysql://localhost:3306/test","root","root"); String query = "select * from employee where name='"+emp_id+"'"; st = conn.createStatement(); ResultSet rs = st.executeQuery(query); while(rs.next()) { data = ":" + rs.getString("address") +":"+ rs.getString("email"); } out.println(data); } catch (Exception e) { e.printStackTrace(); } %>
3)For the above code, we have created following table:
CREATE TABLE `employee` ( `id` bigint(255) default NULL, `name` varchar(255) default NULL, `address` varchar(255) default NULL, `contactNo` int(255) default NULL, `email` varchar(255) default NULL )
