DIV CSS 佈局教程網

先給大家展示下運行效果圖：

 1.後台action產生json數據。

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(",")); // 刪去最後一個逗號 
     sb.append("]}");  
     HttpServletResponse response = ServletActionContext.getResponse();      
     response.setContentType("text/plain"); 
     response.getWriter().print(sb); 

   2.struts.xml相關配置

<action name="blackList" class="blackAction" method="blackList"> 
  <!--plaintext用於顯示頁面原始代碼的結果類型--> 
  <result type="plainText"> 
  <param name="charSet">UTF-8</param> 
  <param name="location">/WEB-INF/jsp/manage/black.jsp</param> 
  </result> 
</action> 

3.js獲取json數據分頁顯示

function getJSONData(pn) { 
  // alert(pn); 
  $.getJSON("blackList.ce", function(data) { 
    var totalCount = data.totalCount; // 總記錄數 
    var pageSize = 10; // 每頁顯示幾條記錄 
    var pageTotal = Math.ceil(totalCount / pageSize); // 總頁數 
    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) {   // 當只有一頁時 
      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;    // 當遍歷到最後一條記錄時，跳出循環 
        } 
        $(".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; // 總記錄數 
        var pageSize = 10; // 每頁顯示幾條記錄 
        var pageTotal = Math.ceil(totalCount / pageSize); // 總頁數 
        $("#next").click(function() { 
              if (pn == pageTotal) { 
                alert("後面沒有了"); 
                pn = pageTotal; 
              } else { 
                pn++; 
                gotoPage(pn); 
              } 
            });

              }
