Setting all jsp fields to null...database data...Javaranch trigger

[Tokunbo Oke]

Please, what is the most efficient way to set all fields to null in my jsp?

I have just noticed that the reset button - HTML:RESET only clears unsubmitted data. It does not clear data retrieved from the database. Can you please shed some light on why this is the case?

I am wondering if I have to add an on click event to the reset button that forward to a mapping-->class.method-->formBean that sets all the fields to null in the formBean.

Note: My action class, extends MappingDispatchAction.


Furthermore, is there a trigger in Javaranch that I can switch on, so that when I log in, all my postings and the ones that I have responded to will automitically come into view?

Thank you.

Ola.

Usually resets in a browser don't clear the values, they reset them to the originals from when the page loaded.

If you view the source of the html in your browser you will notice that many of the input tags have a value attribute. This is the value that the forms "resets" to.

Noted. Thanks.

on reset you can drop the bean reference from the session or have a clearValues method in your bean that will clear all bean values.
