I am trying to add a message in my jsp after the process is done by hitting the submit button.
function onSubmit() {
alert("Master_Data.xlsx and Consistency_Check_Data.xlsx are located under d:/stage/MasterDataReports");
}
</script>
<body>
<form name="input" action="getMasterData" method="get">
<br />
<br />
<h1 align='center'>Master Data File</h1>
<br />
<br />
<table border="0" align='center'>
<tr>
<td>
<h2>Site Name</h2>
</td>
<td align='left'>
<jsp:useBean id="masterDao" class="master.dao.MasterDataDao"/>
<select name="siteId" id="siteId">
<option value="0">ALL</option>
<c:forEach items="${masterDao.allSites}" var="siteDto">
<option value="${siteDto.id}">${siteDto.name}</option>
</c:forEach>
</select></td>
</tr>
<tr>
<td>
<h2>Division</h2>
</td>
<td align='left'>
<jsp:useBean id="masterDaoUtil" class="master.dao.util.MasterDataConstants"/>
<select name="divisionId" id="divisionId">
<option value="33"><%=MasterDataConstants.DIVISION_TYPE_AUDIT_MANAGEMENT_GLOBAL_NAME%></option>
<option value="31"><%=MasterDataConstants.DIVISION_TYPE_CHANGE_MANAGEMENT_GLOBAL_NAME%></option>
<option value="34"><%=MasterDataConstants.DIVISION_TYPE_DEA_MANAGEMENT_GLOBAL_NAME%></option>
<option value="35"><%=MasterDataConstants.DIVISION_TYPE_EHS_MANAGEMENT_GLOBAL_NAME%></option>
<option value="23"><%=MasterDataConstants.DIVISION_TYPE_EVENT_MANAGEMENT_GLOBAL_NAME%></option>
</select></td>
</tr>
</table>
<br />
<br />
<div style="text-align: center">
**strong text**<input type="submit" value="Submit" OnClick="onSubmit()">
</div>
Right now the submit process will only happen after I clear the alert. Is there a way that I can either pop an alert after the submit process is done or if I can add a message to the jsp page? Thanks in advance Sonny
Here is my updated Servlet that is causing error:
package master.service;
import java.io.IOException;
import java.sql.SQLException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
**strong text**import javax.servlet.http.HttpSession;
@SuppressWarnings("serial")
public class MasterDataServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response, HttpSession session)
throws IOException, ServletException {
MasterDataService masterDataService = new MasterDataService();
try {
int siteId = Integer.parseInt(request.getParameter("siteId"));
int divisionId = Integer.parseInt(request.getParameter("divisionId"));
//For master data file
masterDataService.createMasterDataFile(siteId, divisionId,false);
//For consistency checker file
masterDataService.createMasterDataFile(siteId, divisionId,true);
request.getRequestDispatcher("/masterDataQueryScreen.jsp").forward(request, response);
**strong text**session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
**strong text**response.sendRedirect("/masterDataQueryScreen.jsp");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
To create a JSP error page, we need to set page directive attribute isErrorPage value to true, then we can access exception jsp implicit object in the JSP and use it to send customized error message to the client.
So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.
In test.jsp
Create a javascript
<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
}
</script>
and than at the bottom
<script type="text/javascript"> window.onload = alertName; </script>
Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to
Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.
To do that i would highly recommendation to use session!
So what you want to do is in your servlet:
session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);
than in the test.jsp
<%
session.setMaxInactiveInterval(2);
%>
<script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
if (Msg != "null") {
function alertName(){
alert("Form has been submitted");
}
}
</script>
and than at the bottom
<script type="text/javascript"> window.onload = alertName; </script>
So everytime you submit that form a session will be pass on! If session is not null the function will run!
