Button as link and submitter

[Mr Jimmy，修改在9 年前。]

Excuse me please to post again a problem, but then I will be done with my UI and with alloy it already looks great

I want a button as a link and as a submitter of a value to a method in my MVCPortlet class.
The link is inside a java array.
The attribute that is passed to the java method is inside a input field.

It works if I do just one of this two (for both).
I tried to combine them but it doesn't work.
I tried this:

<a href="<%=unread[i][k]%>" target="_blank">
<aui:button type="submit" />
</a>

It calls the method but it doesnt opens a new tab in my browser. In my browser I can see that it is a link, if I click right on it -> new tab, it opens it correctly in a new tab. But not if I just click on the button.
Second way:

<aui:button type="submit" onclick="window.open('http://www.google.de', '_blank', ''); return false;" />

It just opens google but doesn't calls the method. Also it seems not possible to get an Java attribute inside of a javascript, but maybe I could get the value out of a hidden input field.

I hope you understand my problem, would be fantastic to get this very good help again,

Sincerely Mr.Jimmy

In the second way, you mentioned above make changes as below.

<aui:button type="submit" onclick="window.open('http://www.google.de', '_blank', '');" />

Here I removed return false statement which was restricting form to submit .
You can get your java attributes/variables inside javascript using EL or scriptlet.
In your case it would be like window.open('<%=unread[k]%>', '_blank', '');

absolutely right!

That hasn't worked for me with

window.open('<%=unread[i][k]%>', '_blank', '');

so I used EL and JSTL, that worked:

<c:set var="url" scope="session" value="<%=unread[i][k]%>" />
<aui:button type="submit" onclick="window.open('${url}', '_blank', '');" />

Thank you a lot Pankaj!
