do i have to submit all the time

[Leonardo Go]

i made a page with a form and button in it.
is it possible? that when i click on the button something will happen
(process stuffs) without submitting the form ?
thnx ...

Not Exactly,

you may do your processing using a javascript function. When you click on
the button, invoke the javascript function.

Hi Leo,

Like Vijay has replied, write a JavaScript function that will return either true or false based on what you want to do (I mean, the processing that you spoke about). Then, have the following syntax for your form's onsubmit() function:

<form name="myForm" onSubmit="return validateForm()">
 
</form>

So, the form will be submitted only if the JavaScript function validateForm( ) returns true

but can i call a java function i wrote in the jsp using javascript ?
because i was thinking of reacting events using java code instead of javascript.
but i think its not posible right ?

As far as I know, you cannot call a Java method from a JavaScript function.

the JSPs are residing on the server and can only be reached trough HTTP(S) calls so there is no way to invoke your JSPs but to send a HTTP request (by clicking a link or by submitting a form or by some javascript code).

I suppose this thread could find a home in either the JSP forum or the HTML and JavaScript forum.

(Flipping coin...)

Moving this to the HTML and JavaScript forum...

Leonardo,

What you want to do is to submit each action (e.g. add, remove, save, close, etc.) to the server side (your JSP) and handle it there with a controller. The controller, another JSP or perhaps a servlet, which is on the server-side, can then get the supplied action from the request object and call the appropriate Java method to handle the action (do the processing).

You might want to Google for the "Model View Controller" design pattern, which is a time-honoured tradition of achieving the above.
