三、js提交请求加载启动动画、请求完成成功回调、注销加载动画

1、通过Query post方式进行异步请求方法

jQuery.post(url, [data], [callback], [type])

参数说明：

    url:发送请求地址

    data:待发送 Key/value 参数

    callback:发送成功时回调函数

    type:返回内容格式，xml, html, script, json, text, _default

2、要实现的功能描述：js提交请求加载启动动画、请求完成成功回调、注销加载动画
2.1 html页面代码

    <td colspan="10" align="right">

      <input  type="button" value="查询" onclick="seachPage('')">

    </td>

    <body>

    function seachPage(pageDirection) {

     var levs = getSelectOrglev();

     var sbType = $("#sbtype").val();

     var jyType = $("#jytype").val();

     var custname = $("#custname").val();

     var begindate = $("#begindate").val();

     var enddate = $("#enddate").val();

     if (!checkDate(begindate, enddate)) {

      alert('截止期必须大于或等于起始日期');

      return false;

     }

     var currentpagevalue = $("#currentpagevalue").val();

     initLoading();// 启动加载动画

     $.post("dataAuditAction.do?action=findAuditList",

            {

              orgLevel : levs,

              sbtype : sbType,

              jytype : jyType,

              begindate : begindate,

              enddate : enddate,

              pageDirection : pageDirection,

              currentPage : currentpagevalue,

              custName : encodeURI(custname)

             },

            function(data) {//回调函数

              var arr = data[0].auditList;

              if (arr.length > 0) {

               var html = "";

               for ( var i = 0; i < arr.length; i++) {// 更新列表

                var dataBean = arr[i];

                html += "<tr><td><input type='radio'  name='reportId' value='" + dataBean.dataId + "'/></td>";

                html += "<td align='center'>" + dataBean.finishDate + "&nbsp;</td>";

                html += "<td align='center'><input type='button' value='查看' onclick=searchAudit('auditAction.do?action=auditDetail&insurCode="+dataBean.dataId+"')>" + "&nbsp;</td></tr>";

               }

           //

           var allsize = data[0].allSize;

           var currentpage = data[0].currentpage;

           cleartable(0);// 清空表格

           $("#tablelist").append(html);

           hideLoading();// 取消动画

           $("#allSize").append(data[0].allSize);

           $("#currentpage").append((parseInt(data[0].currentpage) + parseInt(1)));

           changePage(allsize, currentpage);// 更新翻页

           $("#currentpagevalue").val(currentpage);

          } else

           cleartable(0);

          hideLoading();// 取消动画

         }, "json");

    }

        //1、对日期值进行比较

    function checkDate(beginDate, endDate) {

        if (beginDate != '' && endDate != '') {

        if (endDate >= beginDate)

         return true;

        else

         return false;

        } else

        return true;

    }

    //2、开启动画

    function initLoading(){

        var loadDiv = '<div id="loading" class="ol_loading">加载中····</div>';

        $('body').append(loadDiv);

        $.blockUI({fadeIn:1000,fadeOut:700,message:$('#loading'),overlayCSS:{backgroundColor:'#CECEC6',opacity:'0.2'}});

    }

    //3、注销动画

    function hideLoading(){

        $.unblockUI();

    }

    //4、类选择器

    .td-c{

        background-color:#c4d6ee;

        border-right:1px solid #3f79a3;

        border-bottom:1px solid #3f79a3;

        border-left:1px solid #ffffff;

        border-top:1px solid #ffffff;

        font-size: 13px;

        color:#004f79;

    }

<from>

  <table  id="tablelist" border="0" align="center" cellpadding="4" cellspacing="0">

   <tr>

   <td align="center" class="td-c">

    <font style="font-family: 宋体 ;font-size: 14px;">选择</font>

   </td>

   <td align="center" class="td-c">

    编号

   </td>

   <td align="center" class="td-c">

    操作

   </td>

   </tr>

  </table>

 </from>

 <div align="right">

  当前第<label class="page" id="currentpage" ></label>页/<label class="page" id="allSize" ></label>页

  <label id="first" style="display: inline;">首页 前一页</label>

  <span id="first1" style="display: none;">

   <a  style="display: inline" onclick="javascript:seachPage('first')" href="##"  class="a1">首页</a>

   <a  onclick="javascript:seachPage('previous')" href="##"  class="a1">前一页</a>

  </span>

  <label id="last" style="display: inline">后一页 末页</label>

  <span id="last1" style="display: none;">

         <a onclick="javascript:seachPage('next')" href="##" class="a1">后一页</a>

         <a onclick="javascript:seachPage('last')" href="##"  class="a1">末页</a>

  </span>

  <input id="currentpagevalue" type="hidden" value="0">

 </div>

</body>

2.2 java查询代码

  List auditList = kyDataAuditService.getAuditAllDataList(map, paper, currentPage, pageDirection, 10);

  map.put("auditList", auditList);

  map.put("currentpage", String.valueOf(paper.getCurrentpage()));

  map.put("allSize", String.valueOf(paper.getAllSize()));

  response.getWriter().write(JSONArray.fromObject(map).toString());

  response.getWriter().flush();

  response.getWriter().close();

  return null;
