Hi,

This is really very basic question but I am not clear. This is my signIn.jsp file:



How can I send three different events from the same form?

In other words, There are three buttons at my page and I want different action on each click of each button. How could I do this??? or how can I know at server side that which button has been clicked by user???

I am sure there must be many ways of doing this, please tell me the simpler one and best one.

Thanks a lot.

Or, use Javascript to change the action of the form upon clicking one of the submit buttons.

But all the requests are going first to MainController servlet so action is same in all the cases.

Sounds like you are using Front Controller Pattern. You can make the decision in your MainController on the basis of button value, as Oswald King already suggest said.

Think of implementing Command Pattern.

in the same way for below two also.
<INPUT type="submit" value="Sign Up" action="b.html">
<INPUT type="submit" value="Forgot Password" action="c.html">



Nonsense. There is no action attribute on the input tag.

this is where the beauty of struts comes into play (or any standardized framework for that matter). Struts has a DispatchAction w/ an actionMethod defined in the struts action definition for this use case. why try to reinvent the wheel instead of using the wheel for leverage.

Because sometimes the wheel becomes a monster truck tire when a bicycle tire would have sufficed. Sometimes reinventing the wheel is a good thing.

Adopting a bloated behemoth like Struts in order to accomplish a simple switch would be a tad bit of overkill, in my opinion.

hey, don't shoot the messenger. j/k. I agree that this single example here doesn't provide enough of a business case to switch a bunch or adding a bunch of code around. here's some stuff to keep in mind. if he was using a standardized framework he most likely wouldn't be posting this question, he'd be posting a much more difficult question Ha Ha!. But seriously, this problem has already been addressed by someone else and solved. secondly, this is the signIn.jsp. sounds like he's doing more than a 20 action application, so it starts to warrant a standardized approach for long term maintainability, not some home-grown application... of course I could be completely off base.. I did join the party late.

ps.. one other thing.. struts isn't bloated.. JSF is bloated

Hey, dont say a word to JSF.

I always did with my own fabricated framework. After JSF, I joined the JSF team and still working with JSF. Its good a bit immature but real good, simple, sensible. Its a component based framework and easily digestable. JSF is something really works and has a great future.

By the way, the discussion is going off topic.

I guess you dont know what she is doing. From her previous posts I got to know that she made her own mini web framework based on MVC architecture and going great with that, I hope. So, struts, or something else is meaningless for her right now.

I would also suggest the same, what Adeel and Oswald already suggested.

Try This....

<HTML>
<HEAD>
<SCRIPT language="JavaScript">
function processForm(action)
{
if(action == "Sign In")
{
document.frm.action = "MainController";
}
else if(action == "Sign Up")
{
document.frm.action = "MainController1";
}
else if(action == "Forgot Password")
{
document.frm.action = "MainController2";
}
else
{
return;
}
document.frm.submit();

}
</SCRIPT>
</HEAD>
<BODY>
<FORM name="frm" method="post">
username<INPUT type="text" name="username"/><br>
password <INPUT type="text" name="password"/><br>
<br>
<INPUT type="button" value="Sign In" onClic="processForm('Sign In')">
<INPUT type="button" value="Sign Up" onClic="processForm('Sign Up')">
<INPUT type="button" value="Forgot Password" onClic="processForm('Forgot Password')">
</FORM>
</BODY>
</HTML>
