submitting two forms with one button click from JSP

[DeepakN kumar]

Hi,

I have a requirement to submit two forms ( each form to a different strut action class ) on click of a submit button from JSP. Any idea how this can be achieved? Is it OK if i write a java script method and inside the method i write the two form submit as below?

function formSubmit()
{
document.form1.submit();
document.form2.submit();
}

Please let me know if there is any other way of doing it.By the way form1 will submit to a different url (different application) and form2 will submit to an action class on the same application.
Also i have read that two forms can't be submitted from a JSP at the same time.

You cannot submit two requests at the same time. Which one's response would show up in the browser?

Back up. Why do you need to do this. There is surely a better way.

(P.S. You could possibly use Ajax, but I'm not sure that's the best approach.)

That's impossible! Why don't you combine two forms into one, and two actions into one?

[DeepakN kumar]

ok. Let me explain my requirement in detail.

I have an OK button on my JSP and on click of that OK button, i am suppose to send some parameter as POST to another application in a new window( i.e. a new browser window should open on click of OK). At the same time, i also need to forward the request to another screen which is a summary screen on the same application. So it is not possible for me to combine these two activities into one.

Also how Ajax can help here?

If you submit 2 forms, the last one will get submit . so this is not correct approach. and I think, I got your requirement. just follow the below steps,

create 2 forms like below, first one will be your main window and second form will be submitted to your popup(see the target attribute)

<form action="/A/abc" id="main">
<input type="text" name="user"/>
<input type="button" value="Go" onclick="doPopup(this); return false;"/>
</form>
<form action="/A/xyz" id="hidden" target="popup">
<input type="hidden" name="code" value="Hidden" style="display:none;"/>
<input type="submit" value="Enter" id="go"/>
</form>

and onclick javascript

function doPopup(source)
{		
	document.getElementById("main").submit();//it submit the first form	
	popup = window.open("", "popup","width=200,height=200");	
        //if you want to pass some value then 
        //introduce hidden field in 2nd form set the value from here
	document.getElementById("go").click();//it submit the 2nd form
}

does that make sense?

thanks i will try this. But i have one question. Here also there is two form submit right? So in this case also only the last submit will work right? (document.getElementByID('go').click) ? Please could you explain?

[Seetharaman Venkatasamy]

but there are 2 windows . form per window. i.e, submit per window.

[DeepakN kumar]

thanks alot. Also is there a difference between submitting the form by document.getElementById("go").click() and document.getElementById("hidden").submit()? both are same?
