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

   2.struts.xml相关配置

 
   
   
  UTF-8 
  /WEB-INF/jsp/manage/black.jsp 
   
 

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('
'); 
    } 
    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("") 
 .append("" + parseInt(j + 1) 
     + "").append("" + dataRoot[j].mobile 
     + "").append("" + dataRoot[j].province 
     + "").append("" + dataRoot[j].gateway 
     + "").append("" + dataRoot[j].insertTime 
     + "").append("" + dataRoot[j].remark 
     + "") 
      } 
    } 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("") 
 .append("" + parseInt(j + 1) 
     + "").append("" + dataRoot[j].mobile 
     + "").append("" + dataRoot[j].province 
     + "").append("" + dataRoot[j].gateway 
     + "").append("" + dataRoot[j].insertTime 
     + "").append("" + dataRoot[j].remark 
     + "") 
      } 
    } 
    $(".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~
