RE: Way tho highlight error form field

[Joao Batistella]

But, how about server side errors that I can't not validate in Javascript?

I tought about something like this:

<html:text property="test" styleClass="normal_class"
styleClassOnError="error_class"/>
So, if I return an ActionError about the property test, the style class to
use would be error_class, otherwise, normal_class.

I know this doesn't exist in Struts but is there something that can do
something like this?

Thanks

You could modify the client-side validation stuff to do this rather 
than just alerting.

An easy way of layering this on is to define a compulsory array of 
fields and then loop through the form on validation. changing the 
borderColor style attribute when you have a match between the element 
name and your array.


compulsary = ["name","email"];

function validate(form) {
        for(i = 0;i < compulsary.length;i++) {
                field = compulsary[i];
                value = form.elements[field].value;
                if(value == "") {
                        form.elements[field].style.borderColor = "#ff0000";
                }
        }
}

Then you can think about having your compulsary array populated in the 
same way as the struts validator client-side stuff. In fact you could 
use the array then it defines.
