Repopulating fields?

[rajesh mara]

Hi everyone,

I have a doubt of how to repopulate fields with error messages below the fields when one of the fields left with blank.


For example

User name -------(Text Box)
Password ------ (Text Box)
Submit(Button)
if user doesn't enters user name or password i should get display like the following

User name -------(Text Box)
Password ------ (Text Box)
Submit(Button)
- User Name Required(in red marks)
please help me anyone how to get display like above instead of getting an alert prompt.

Thank You.

What are you using on the server? This is something easily accomplished in JSP.

You have all the information on the server -- including the nature of the error that your code just detected. It's an easy matter to use JSP technology to format the HTML as appropriate. You can conditionally create an error message on the page, and fill in the form fields with the previous submitted value for a parameter.

For example, assuming that the JSP is being generated in the same request as the form submission (not always true):

<input type="text" name="fieldName" value="${param.fieldName}"/>    

Conditional markup is easy with the JSTL <c:if> action:

<c:if test="${not empty errorMessage}">
  <div class="errorBlock">${errorMessage}</div>
</c:if>
