执行“查看源代码”时隐藏字段丢失
我的 jsp 表单中有两个隐藏字段。当我在浏览器中获取页面并执行“查看源代码”时，我只能看到第一个隐藏字段，而看不到第二个字段。
<input type="hidden" name="url" id="url" value="<%=url%>" />
<input type="hidden" name="age" id="age" value="<%=age%>" />
语法有错误吗？请帮助
更新：
代码：
<form name="displayForm" action="javascript: submitPage();">
<input type="hidden" name="url" id="url" value="<%=url%>" />
<input type="hidden" name="age" id="age" value="<%=age%>" />
<span class="notice required">* indicates required field</span> Source in the browser is
<form name="displayForm" action="javascript: submitPage();">
<input type="hidden" name="url" id="url" value="unix.com"; />
<span class="notice required">* indicates required field</span>
I have two hidden fields in my jsp form. When i get the page in browser and do 'view source', I could see only the first hidden field, not the second field.
<input type="hidden" name="url" id="url" value="<%=url%>" />
<input type="hidden" name="age" id="age" value="<%=age%>" />
Is the syntax wrong? Please help
Update:
Code:
<form name="displayForm" action="javascript: submitPage();">
<input type="hidden" name="url" id="url" value="<%=url%>" />
<input type="hidden" name="age" id="age" value="<%=age%>" />
<span class="notice required">* indicates required field</span> Source in the browser is
<form name="displayForm" action="javascript: submitPage();">
<input type="hidden" name="url" id="url" value="unix.com"; />
<span class="notice required">* indicates required field</span>

确保为 JSP 提供服务的 tomcat 已实际部署您的更改。尝试找到文件“jspfilename_jsp.java”并查看隐藏字段语句是否确实在其中。您可能想看看 Lambda Probe for Tomcat，它只需单击鼠标即可清理缓存，强制重建。
Make sure that the tomcat serving the JSP has actually deployed your changes. Try to locate the file "jspfilename_jsp.java" and look if your hidden field statements are actually in there. You might want to take a look at Lambda Probe for Tomcat, which cleans the cache with a click of a mouse, forcing a rebuild.
不，它一定在那里。您可能有条件地渲染它。
No. It must be there. You might be conditionally rendering it.
您使用哪种浏览器？您是否尝试使用某种“开发人员工具”（Chrome - 开发人员工具、FF - Firebug、IE8+ - 开发人员工具）来检查它？
当您提交表格时会发生什么，您会得到什么“年龄”？
which browser do you use? Did you try to inspect it with some sort of "developer tool" (Chrome - Developer tools, FF - Firebug, IE8+ - Developer tools)?
When you submit the form what happens, what do you get for "age"?
