Question

我在jsp（Welcome.jsp）页面上有一个Submit按钮，通过该按钮我可以将请求发送到myservlet（Import Parts）。我在servlet中进行了一些验证，验证失败后，我将用户重定向到error.jsp页面，该页面提供了适当的消息。我将响应转发到error.jsp之后，此error.jsp也具有关闭按钮，该按钮不起作用。

如果我直接在浏览器中启动error.jsp并尝试单击关闭按钮，它将起作用。

// Below is the piece of code written in my Servlet on doPost() method which perform some validation and upon failing the validation check redirects user to error.jsp page.

if(!UserDetails.checkValidUser(asession))  //a Validation method returning true or false
            {
                logger.info("User do not have necessary role");
                request.setAttribute("error", EMSImportConstants.NO_PRIVILEGE_USER_ERR_MESSAGE);
                RequestDispatcher rd = request.getRequestDispatcher("/Error.jsp");
                rd.forward(request, response);
            }

//Below is my error.jsp page code

<% 
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<html>
<head>
<title>Error in EMS BOM Import</title>
        <link href="<%=basePath %>/css/netapps.css" rel="stylesheet" type="text/css" /> 
</head>
<body bgcolor="#ffffff" class="borderless">
<form method="post" action="Error.jsp">

 <center>
            <div id="banner">
                <div id="logo"></div>

                <div id="rightbg">
                    <div id="bannerTitle"><br>EMS BOM Import</div>
                </div>
                <div id="bannerImage"> </div>
            </div>
</center>
<br />
<br />
<br />
<br />
<center>
<font size = "2px" color="red">
<%=request.getAttribute("error") %>
</font>
<table>
<tr>
<td align="center"><input type="button" value="Close"  onclick="window.close();"/></td>
</tr>
</table>
</center>
</form>
</body>
</html>


I click on close button but nothing happens.

Answer 1

在表单中，要提交详细信息，input类型应为submit，而不是button。以此方式更改代码。它应该可以工作:)

<form>
  <td align="center"><input type="submit" value="Close" onclick="window.close();" /></td>
</form>

将响应从servlet重定向到jsp后，jsp页面中的“关闭”按钮不起作用
