Question

我有一个jsp视图页面，它使用datatable来显示使用serverSideSearch操作的数据列表。在jsp页面上，我有一个表单用于选择日期和其他一些字段，然后是Generate按钮用于显示数据表。现在的问题是，每当我点击Generate按钮时，它会刷新页面然后显示数据表。我不想刷新页面，数据表必须带来刷新的数据表。这是我的jsp文件：

<%@ page contentType="text/html; charset=ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%> 
<%@ taglib prefix="display" uri="http://displaytag.sf.net" %>
<html>
<head>

<script type="text/javascript">
    $(document).ready(function() {
         if('${pageVisitLogList}' == 'undefined' || '${pageVisitLogList}' == '[]' || '${pageVisitLogList}' == ''){
            $('.container').css('text-align', 'center');
        } 

         var dataTable; //reference to your dataTable

         $('#submitPageLog').click(function() {
             dataTable.fnReloadAjax('pageVisitReport.jsp');
         });

         dataTable= $('#row').dataTable(
        {
            "sDom" : "<'row'<'spanPag'l><'span6'p><'spanSer'f>r>t<'row'<'spanPage'i><'span6'p>>",
            "oLanguage" : {"sLengthMenu" : "_MENU_ records per page"},
            "bServerSide": true,
            "sAjaxSource": "serverSideSearch.action?dateFrom="+$('#fromDate').val()+"&dateTo="+$('#toDate').val(),

                              { "mDataProp": "facility"},
                              { "mDataProp": "visitTime"},
                              { "mDataProp": "module"},
                              { "mDataProp": "pageVisited"}, 

                          ]   

        }); 


        $("#fromDate").datepicker({
         showOn: 'both',
         buttonImage: "Reports/resources/images/calendar.gif",
         buttonImageOnly: false,
         changeMonth: false,
         changeYear: false,
         showAnim: 'slideDown',
         duration: 'fast'

        $("#toDate").datepicker({

我搜索并尝试使用fnReloadAjax()，但它不起作用。页面令人耳目一新......

首先应该尝试一个简单的Ajax示例并尝试理解它。您可以参考：A Simple AJAX with JSP example

或者可能是更精致的东西，这肯定会有所帮助 http://www.codecoffee.com/articles/ajax.html

在提交时避免在jsp中自动刷新页面。
