请教：在html里我怎摸样才能把表单的内容向二个页面里提交呢？

1<form action="a1.jsp" method="post" name="f1">
2<form action="a1.jsp" method="post" name="f2">
3<input name="ss" type="text"/>
4<input type="submit"/>
5<input type="submit"/>
6</form>
7</form>

1<input name="B1" onclick="this.form.action='a1.jsp';this.form.submit()" type="button" value="提交1"/>

1<input name="B2" onclick="this.form.action='a1.jsp';this.form.submit()" type="button" value="提交2"/>
