jquery在页面第二次加载的时候触发不了下拉框的change事件,启动tomcat,地址栏输入localhost:8080/aa/list.jsp时能够触发下拉框的change事件,但是从servlet过来后就不起作用了,怎么回事?

信息界面$(document).ready(function(){
$("#sel_emp").live('change',function(){
var value = $('#sel_emp').val();
alert(value);
window.location = "/aa/servlet/Test1Servlet";
});
});
编号
姓名
编号 | 姓名 |
---|---|
${element.uid } | ${element.username } |
------------------------servletprotected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Employee employee_01 = new Employee();
employee_01.setUid("1");
employee_01.setUsername("张三");
Employee employee_02 = new Employee();
employee_02.setUid("2");
employee_02.setUsername("李四");
List list = new ArrayList();
list.add(employee_01);
list.add(employee_02);
request.setAttribute("list", list);
request.getRequestDispatcher("/list.jsp").forward(request, response);
问题补充:
你是指,在从servlet 跳转至该页面后,点击下拉菜单,选择一个值的时候,不会触发这下面这个:
引用# function(){
#
# $("#sel_emp").live('change',function(){
# var value = $('#sel_emp').val();
# alert(value);
# window.location = "/aa/servlet/Test1Servlet";
# }
是么?
是的
