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

1. L'action en arrière-plan génère des données json.

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. Configuration associée à struts.xml

<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 récupère les données json et les affiche dans les pages

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(&#39;<li class="li-tag"></li>&#39;);
    }
    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=&#39;col1&#39;><input type=&#39;checkbox&#39; value=&#39;"+parseInt(j + 1)+"&#39;/></span>")
