JSP Form Validation

[aarushi2001]

Hi,

I have created a form, which takes and displays user information. I want to add form validation to my form. So far I have been able to validate email, text fields but I dont know how to validate a drop-down (list) field.

I have been able to prompt the user for error if no value is selected but even if user selects a value, it still asks user to select.

Thanks

Are you talking about client-side or server-side validation?

I want to validate my form using JSP and beans. I am not able to validate drop-down box (been able to validate check box, textfield and stuff).

Perhaps you should say in what ways you are failing to validate :

Does the required value come through ?
What do you determine as "valid" ?
What data are you getting ?
If getting no data, what are you expecting.

its hard to diagnose a problem when all you say is "It doesn't work" ...

I did mention what exactly is the problem in my first post of this thread.

In detail:
a user has to select a state. If a user does not select a state, then he should be prompted for an error.

My problem:
even if a user selects a state, he is prompted to select a state.

Data expectation:
If a user selects a state, when he submits or clicks on submit, a page is being dispayed which displays the values entered by the user. In state section, state name should be displayed.
I am not getting any value, cos, till the time user doesnt select the state, he cannot proceed onto next section (basically submit info)

Thanks

I still think this is a job for client-side validation, ie, prior to submitting. Javascript is your language.

So, as I asked before, what values are you getting ? What values are you expecting.

I would like to see something like this :

Here is my form variable :

<select name="myVar">
  <option value="one">one</option>
  <option value="two">two</option>
</select>

In my Java/JSP (or whatever) I do :

String myVar = request.getParameter("myVar");

Now what I get is "blahbla", but what I really need is "blaBLA".

If you don't get specific - then how can we help you ?
My advise without any info like above would be "it seems broken - I would suggest fixing it" !

I did explain properly...

 

[Diancecht]

Sure, you did explain ok, but no one understood you.

Glad you got it to work, because with your explanations and attitude I doubt anyone could offer any help.

Cheers,
Dian

 

[aarushi2001]

Dian, sorry if my explanation was bad and for my attitude but ppl can also ask ques in a better way.

No offense..

 

[Diancecht]

No problem, I'm not offended at all, just trying to say that if people don't understand your questions, will be very difficult that can provide any answers.

Cheers,
Dian
