how to validate field right after the data is entered

Hi,

 

We want to validate the field data right after the data is entered. So
that the user can fix the error right away instead of waiting until the
whole form is submitted.

We thought that struts2 and ajax can help us on that. But what would be
the best way to do?

 

Any helps or guidance are appreciated.

 

Thanks,

Mei

i dont think ull run into problems atleast as long as u reatain the theme as
ajax.

try using theme as simple and give onblur="validate(this);". Also include
the necessary .js files (make the necessary ajax configurations and view
source in browser, ull see the .js files). check if the .js files are being
served to the browser. (fire bug of mozilla would help u)

basically a new node <td> is created and error is written into it (addError
of validate.js)

function addError(e, errorText) {
    try {
        // clear out any rows with an "errorFor" of e.id
        var row = e.parentNode.parentNode;
        var table = row.parentNode;
        var error = document.createTextNode(errorText);
...

so this approach should resolve ur issues.

regards,
ravi

Thank you!! This is a really detailed document. I finally got this
problem solved.
But now I noticed that the javascript creates html nodes to display
error message dynamically. If I changed the layout then it does not work
well.
For example, if I have 4 columns in the table to display two fields.
Do you or anyone have any experience about this?

Thanks,
Mei

Thanks, I looked at this document. I think it is more referring to 2.1
which does not have a stable release yet.
We prefer to use 2.0.11 since it is the latest stable release.

I was thinking about something like in the showcase example (quiz-ajax).
That we need to write a javascript function to listen to onblur() event
on the input text field. But I am not sure how to ask struts to validate
for this particular field, and how to get the error message back from
the response.
Can anyone help me on this?

Thanks,
Mei
