我选择“选择”哪些选项是“编辑”，“删除”。当我点击“编辑”时，页面会很好地转到“edit_product.jsp”。但是当我点击“删除”时，页面再次转到“edit_product.jsp”，而不是“delete_product.jsp”。我想只点击选择选项，即其他页面 - “编辑”是“edit_product.jsp”，“删除”是“delete_product.jsp” - 。
这是代码。
[]我使用jQuery和jsp。 <%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<% request.setCharacterEncoding("utf-8"); %>
<%@ page language="java" import="java.sql.*,java.util.*" %>

只能使用一个吗？我使用的是window.location.href，但没有对if else if采取任何措施。我该怎么用？请回答我。

是的，您可以多次使用window.location.href。
window.location.href="edit_product.jsp?code="+$('.edit_select option[name=edit]:selected').val();
您也可以使用jQuery - load
$( "#result" ).load( "ajax/test.html" );

要获取所选值名称属性，请使用此
cout << iter->segment << endl;这应该会将您重定向到相应的页面。
