使用Jquery+Ajax+Json如何实现分页显示附JAVA+JQuery实现异步分页

先给大家展示下运行效果图：

 1.后台action产生json数据。

List blackList = blackService.getBlackInfoList(mobileNum, gatewayid, startDate, endDate); int totalRows = blackList.size(); StringBuffer sb = new StringBuffer();      sb.append("{\"totalCount\":\""+totalRows+"\",");      sb.append("\"jsonRoot\":[");      for (int i=0;i<blackList.size();i++) {        LBlack blackInfo = (LBlack)blackList.get(i);        sb.append("{\"id\":\""+ blackInfo.getId());        sb.append("\",");         sb.append("\"mobile\":\""+ blackInfo.getMobile());        sb.append("\",");         sb.append("\"province\":\""+ blackInfo.getProvince());        sb.append("\",");         sb.append("\"gateway\":\""+ blackInfo.getGateway());        sb.append("\",");        sb.append("\"insertTime\":\""+ blackInfo.getInsertTime());        sb.append("\",");        sb.append("\"remark\":\""+ blackInfo.getRemark());        sb.append("\"");        sb.append("},");      }      sb.deleteCharAt(sb.lastIndexOf(",")); // 删去最后一个逗号      sb.append("]}");       HttpServletResponse response = ServletActionContext.getResponse();           response.setContentType("text/plain");      response.getWriter().print(sb); 

   2.struts.xml相关配置

<action name="blackList" class="blackAction" method="blackList">   <!--plaintext用于显示页面原始代码的结果类型-->   <result type="plainText">   <param name="charSet">UTF-8</param>   <param name="location">/WEB-INF/jsp/manage/black.jsp</param>   </result> </action> 

3.js获取json数据分页显示

function getJSONData(pn) {   // alert(pn);   $.getJSON("blackList.ce", function(data) {     var totalCount = data.totalCount; // 总记录数     var pageSize = 10; // 每页显示几条记录     var pageTotal = Math.ceil(totalCount / pageSize); // 总页数     var startPage = pageSize * (pn - 1);     var endPage = startPage + pageSize - 1;     var $ul = $("#json-list");     $ul.empty();     for (var i = 0; i < pageSize; i++) {       $ul.append('<li class="li-tag"></li>');     }     var dataRoot = data.jsonRoot;     if (pageTotal == 1) {   // 当只有一页时       for (var j = 0; j < totalCount; j++) {         $(".li-tag").eq(j).append("<span class='col1'><input type='checkbox' value='"+parseInt(j + 1)+"'/></span>")         .append("<span class='col2'>" + parseInt(j + 1)             + "</span>").append("<span class='col3'>" + dataRoot[j].mobile             + "</span>").append("<span class='col4'>" + dataRoot[j].province             + "</span>").append("<span class='col5'>" + dataRoot[j].gateway             + "</span>").append("<span class='col6'>" + dataRoot[j].insertTime             + "</span>").append("<span class='col7'>" + dataRoot[j].remark             + "</span>")       }     } else {       for (var j = startPage, k = 0; j < endPage, k < pageSize; j++, k++) {         if( j == totalCount){           break;    // 当遍历到最后一条记录时，跳出循环         }         $(".li-tag").eq(k).append("<span class='col1'><input type='checkbox' value='"+parseInt(j + 1)+"'/></span>")         .append("<span class='col2'>" + parseInt(j + 1)             + "</span>").append("<span class='col3'>" + dataRoot[j].mobile             + "</span>").append("<span class='col4'>" + dataRoot[j].province             + "</span>").append("<span class='col5'>" + dataRoot[j].gateway             + "</span>").append("<span class='col6'>" + dataRoot[j].insertTime             + "</span>").append("<span class='col7'>" + dataRoot[j].remark             + "</span>")       }     }     $(".page-count").text(pageTotal);   }) } function getPage() {   $.getJSON("blackList.ce", function(data) {         pn = 1;         var totalCount = data.totalCount; // 总记录数         var pageSize = 10; // 每页显示几条记录         var pageTotal = Math.ceil(totalCount / pageSize); // 总页数         $("#next").click(function() {               if (pn == pageTotal) {                 alert("后面没有了");                 pn = pageTotal;               } else {                 pn++;                 gotoPage(pn);               }             });         $("#prev").click(function() {               if (pn == 1) {                 alert("前面没有了");                 pn = 1;               } else {                 pn--;                 gotoPage(pn);               }             })         $("#firstPage").click(function() {               pn = 1;               gotoPage(pn);             });         $("#lastPage").click(function() {               pn = pageTotal;               gotoPage(pn);             });         $("#page-jump").click(function(){           if($(".page-num").val() <= pageTotal && $(".page-num").val() != ''){             pn = $(".page-num").val();             gotoPage(pn);           }else{             alert("您输入的页码有误！");             $(".page-num").val('').focus();           }         })         $("#firstPage").trigger("click");       }) } function gotoPage(pn) {   // alert(pn);   $(".current-page").text(pn);   getJSONData(pn) } $(function() {   getPage(); }) 

ps：JAVA+JQuery实现异步分页

最近一个项目要求实现异步分页，简单的写了一下，不好的请指出~
