javaScript解决Form的嵌套

HTML是不允许FORM嵌套的，用一个简单的JAVASCRIPT就可以解决问题了

  <script   language=javascript>
  function   process(v){
  if(v=="in"){
  document.theForm.action="in.jsp";
  }else{
  document.theForm.action="out.jsp";
  }
  document.theForm.submit();
  }
  </script>   

  <form   name=theForm   method=post>
  <input   type=text   name=username>
  <input   type=text   name=password>
  <input   type=button   name=login   value=LOGIN   onclick="process('in')">
  <input   type=button   name=logout   value=LOGOUT   onclick="process('out')">
