我想通過點擊id =「test」的href鏈接加載Ajax加載器圖像。點擊這個href後,我想調用一個Jsp Servlet,它會發送一個新的請求來加載一個新的.jsp頁面。Ajax調用servlet並加載新頁面
現在的問題是該servlet將被調用,但他不會對新頁面發出請求。有人可以幫我嗎?
我的代碼如下所示:
jsp頁面:HREF鏈接和裝載機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調用:
<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
$('#laden').removeClass('loader');
}
});
});
</script>
這是該部分將包括一個新的jsp頁面由servlet responseDispatcher:因爲我用的JavaEE但據我記得標準的方式來呈現JSP是使用RequestDispatcher.forward()
方法,如果你不串聯輸出
<c:when test="${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>
我想使用裝載程序img加載新的jsp頁面。我將使用requestDispatcher設置此頁面的位置。 – CodeWhisperer
