问题回答

由于<代码>ServletRequest只适用于服务器, your在浏览器上。 很容易混淆差异,因为服务器上运行的代码和浏览器上运行的代码经常在同一文档中写成(<>tServlet.java或somePage.jsp),因此,你必须记住,什么时候会坐下来。

您的can作为通过从<编码>request>检索到 Java本的的信息的一种方式,将数据放在服务器一侧的网页结构中。 该网页及其结构随后传至浏览器, Java本可以进入客户方的全页结构。 因此,你在<编码>servlet中提出了这样的内容:

<form name="data" action="" >
    <input type="hidden" id="parmEmpId"
        value= <%= request.getParameter( "EMPLOYEE_NUMBER" ) %>  />

    <input type="hidden" id="parmServerName"
        value="<%= request.getServerName() %>" />
</form>

然后,在 Java,你可以把数据从网页上删除:

var employeeId = $("#parmEmpId").val();    //Using jQuery
var server = $("#parmServerName").val();   //Using jQuery
