在开发工作共我们往往会遇到一个表单需要包含多个action不同的提交动作，这时候就不能在使用submit按钮来进行提交了，下面提供通过js来实现这一功能的方法.

示例代码:

<form name="demo" method="post">

<!--YOUR DATA AREA-->

<input type="button" value="添加" onclick="addAction()">

<input type="button" value="删除" onclick="deleteAction()">

<input type="button" value="保存" onclick="saveAction()">

<input type="button" value="查询" onclick="searchAction()">

</form>

<script type="text/javascript">

function addAction(){

    document.demo.action="your add method url";

    document.demo.submit();

}

function deleteAction(){

    document.demo.action="your delete method url";

    document.demo.submit();

}

function saveAction(){

    document.demo.action="your add save url";

    document.demo.submit();

}

function searchAction(){

    document.demo.action="your serach method url";

    document.demo.submit();

}

</script>

//==================

demo中的代码(JSP中的hidden):

 <%@ page language="java" contentType="text/html; charset=UTF-8"

     pageEncoding="UTF-8"%>

 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

 <html>

 <head>

 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

 <title>Insert title here</title>

 <script type="text/javascript">

     function trimStr(str){

         return str.replace(/(^\s*)|(\s*$)/g,"");

     }

     function redisSearchSubmit(){

         document.getElementById("searchtype").value = "Redis查询";

         document.form1.submit();

     }

     function jdbcSearchSubmit(){

         document.getElementById("searchtype").value = "JDBC查询Mysql";

         document.form1.submit();

     }

     function hibernateSearchSubmit(){

         document.getElementById("searchtype").value = "Hibernate查询Mysql";

         document.form1.submit();

     }

     function check(){

         // 节目名

         var assetname = document.form1.assetname.value;

          if(trimStr(assetname) == ""){

             alert("您输入的节目名是空格,请重新输入");

             return false;

         }

         // 导演

         var director = document.form1.director.value;

         // 编剧

         var screenwriter = document.form1.screenwriter.value;

         //主演

         var actor = document.form1.actor.value;

     }

 </script>

 </head>

 <body>

     <FORM name="form1" METHOD=POST ACTION="${ pageContext.request.contextPath }/redisSqlSearch" onsubmit="return check();">

     <input type="hidden" name="searchtype" id="searchtype" value="" />
