    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;iblackList.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(){
