我想在点击带有id =" test"的href链接时加载Ajax加载器图像。单击此href后,我想调用一个Jsp Servlet,它将发送一个新的请求来加载一个新的.jsp页面。
此时的问题是servlet将被调用,但他没有对新页面发出请求。有人可以帮帮我吗?
我的代码如下所示:
jsp页面:href link和loader div
<div id="load"></div>
<a href="#" id="test" title="#" class="mainLink">link</a>
的Servlet
public class TestController extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
// redirect to post
doPost(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
// send to new jsp page
request.setAttribute(getServletContext().getInitParameter("DynamicContentLoader"),"/secure/pages/test/testPage.jsp");
request.getRequestDispatcher("/collector.jsp").include(request, response);
}
}
Ajax电话:
<script type="text/javascript">
$("#test").click(function(e){
e.preventDefault();
$.ajax({
type: "POST",
url: "secure/TestController.do",
beforeSend : function(xhr, opts){
//show loading gif
$('#load').addClass('loader');
},
success: function(){
// nothing to do at this time
},
complete : function() {
//remove loading gif
$('#laden').removeClass('loader');
}
});
});
</script>
这是servlet responseDispatcher将包含一个新的jsp页面的部分:
<c:when test="${not empty requestScope.includeJspContent}">
<!-- start Dynamic Generated Context -->
<jsp:include page="${requestScope.includeJspContent}" />
<!-- end Dynamic Generated Context -->
</c:when>
<c:otherwise>
<!-- start no dynamic data found -->
<jsp:include page="/error/no_dynamic_content.jsp" />
<!-- end no dynamic data found -->
</c:otherwise>
答案 0 :(得分:0)
自从我使用JavaEE以来已经过了太多年,但据我记得,渲染jsp的标准方法是使用RequestDispatcher.forward()
方法,如果不连接输出。也许这也是问题所在。
但我可以肯定的是,您不会将您的回复包括在您的网页中。将其添加到您的success
处理程序:
success: function(resp){
$('#load').removeClass('loader');
$('#load').html(resp);
},
