datatables使用示例

datatables的用法：

Initialisation code

$(document).ready(function() { $('#example').dataTable( { "bProcessing": true, "bServerSide": true, "sAjaxSource": "../examples_support/server_processing.php" } ); } );

Server side (PHP) code

1、datatables分页显示

html代码： <table class="table table-bordered table-striped table-hover table-heading beauty-table" id="usertable">                          <thead>                               <tr>                                    <th>编号</th>                                    <th>用户名</th>                                    <th>状态</th>                                    <th>头像</th>                                    <th>邮箱</th>                               </tr>                          </thead>                          <tbody>                          <!-- Start: list_row -->                                                       <!-- End: list_row -->                          </tbody>                          <tfoot>                               <tr>                                    <th>编号</th>                                    <th>用户名</th>                                    <th>状态</th>                                    <th>头像</th>                                    <th>邮箱</th>                               </tr>                          </tfoot>                     </table> <script type="text/javascript"> // Run Datables plugin and create 3 variants of settings function AllTables(){      userTable();      LoadSelect2Script(MakeSelect2); } function MakeSelect2(){      $('select').select2();      $('.dataTables_filter').each(function(){           $(this).find('label input[type=text]').attr('placeholder', 'Search');      }); } $("#usersubmit").click(function() {      var artdata=$("#userform").serialize();      $.ajax({        type: 'POST',        url: "{:U('Index/adduser')}",        datatype:'text',        data: artdata      })      .done(function( msg ) {           alert( "Data Saved: " + msg );      }); }); $('#myshow').click(function(){      $('#myModal').modal({         show:true,         backdrop:'static',      }); }); $(document).ready(function() {     LoadFineUploader(FileUpload);      // Add tooltip to form-controls      $('.form-control').tooltip();      LoadSelect2Script(DemoSelect2);      // Load Datatables and run plugin on tables      LoadDataTablesScripts(AllTables);      // Load example of form validation      LoadBootstrapValidatorScript(DemoFormValidator);      WinMove(); }); </script> js代码： function userTable(){      $('#usertable').dataTable({           "aaSorting": [[ 0, "asc" ]],           "processing":true, //          "serverSide": true,           "bServerSide": true,      //     "paginate": true,         "sAjaxSource": "Index/userlist",           "sServerMethod": "POST",//特别注意该项设置。当在本地调试的时候没有设置此项，表格正常显示。当放在线上的时候分页数据可以显示，表格内容为空。查看发现aaData数据能从php中获取，但是前台页面就是不显示。最后加上此项才得以显示           "sDom": "rt<'box-content'<'col-sm-6'i><'col-sm-6 text-right'p><'clearfix'>>",           "sPaginationType": "bootstrap",      //     "iDisplayLength": 5,           "oLanguage": {                "sSearch": "",                "sInfo": "从 _START_ 到 _END_ /共 _TOTAL_ 条数据",                "sInfoFiltered": "(筛选自 _MAX_ 条数据)",                "sProcessing": "正在加载数据...",                "sLengthMenu": '_MENU_',                "oPaginate": {                "sFirst":      "First",                "sLast":       "Last",                "sNext":       "下一页",                "sPrevious":   "上一页"              }           },           "aoColumns": [             { "mData": 'id'},             { "mData": 'name'},             { "mData": 'status'},             { "mData": 'avata'},             { "mData": 'email'}           ]      }); } php代码： public function userlist(){           header("Content-type: text/html; charset=utf-8");           $sth = $this->dbh->query("select count(*) as counts from pos_user");//id name password status avata email             $count=$sth->fetch(PDO::FETCH_ASSOC);           $iTotal = $count['counts'];           $sLimit = "";           if ( isset( $_GET['iDisplayStart'] ) && $_GET['iDisplayLength'] != '-1' )           {                $sLimit = "LIMIT ".mysql_real_escape_string( $_GET['iDisplayStart'] ).", ".                     mysql_real_escape_string( $_GET['iDisplayLength'] );           }           if ( isset( $_GET['iSortCol_0'] ) )           {                $sOrder = "ORDER BY  ";                for ( $i=0 ; $i<intval( $_GET['iSortingCols'] ) ; $i++ )                {                     if ( $_GET[ 'bSortable_'.intval($_GET['iSortCol_'.$i]) ] == "true" )                     {                          $sOrder .= $aColumns[ intval( $_GET['iSortCol_'.$i] ) ]."                               ".mysql_real_escape_string( $_GET['sSortDir_'.$i] ) .", ";                     }                }                              $sOrder = substr_replace( $sOrder, "", -2 );                if ( $sOrder == "ORDER BY" )                {                     $sOrder = "";                }           }                $stmt = $this->dbh->prepare("select SQL_CALC_FOUND_ROWS id,name,status,avata,email from pos_user $sLimit ");           $stmt->execute();           $data=$stmt->fetchAll(PDO::FETCH_ASSOC);           $rResultFilterTotal=$this->dbh->prepare("SELECT FOUND_ROWS() as resultsrows");           $rResultFilterTotal->execute();           $aResultFilterTotal = $rResultFilterTotal->fetchAll(PDO::FETCH_ASSOC);           $iFilteredTotal = $aResultFilterTotal[0]['resultsrows'];          $aaData = array();        foreach($data as $k=>$v){           $aaData[$k]['id']=$v['id'];           $aaData[$k]['name']=$v['name'];           $aaData[$k]['status']=$v['status'];           $aaData[$k]['avata']=$v['avata'];           $aaData[$k]['email']=$v['email'];        }        $outputs=array();        $outputs['sEcho']= intval($_GET['sEcho']);        $outputs['iTotalRecords']=$iTotal;        $outputs['iTotalDisplayRecords']=$iFilteredTotal;        $outputs['aaData']=$aaData;        echo(json_encode($outputs));               }

2、自定义列的内容，使用mRender

$('#usertable').dataTable({           "aaSorting": [[ 0, "asc" ]],           "processing":true, //          "serverSide": true,           "bServerSide": true,      //     "paginate": true,         "sAjaxSource": "Index/userlist",           "sServerMethod": "POST",           "sDom": "rt<'box-content'<'col-sm-6'i><'col-sm-6 text-right'p><'clearfix'>>",           "sPaginationType": "bootstrap",      //     "iDisplayLength": 5,           "oLanguage": {                "sSearch": "",                "sInfo": "从 _START_ 到 _END_ /共 _TOTAL_ 条数据",                "sInfoFiltered": "(筛选自 _MAX_ 条数据)",                "sProcessing": "正在加载数据...",                "sLengthMenu": '_MENU_',                "oPaginate": {                "sFirst":      "First",                "sLast":       "Last",                "sNext":       "下一页",                "sPrevious":   "上一页"              }           },           "aoColumns": [             { "mData": 'id'},             { "mData": 'name'},             {               "mData": 'status',               "mRender": function ( data) {                     if (data==1)                     return '<font color="green">正常</font>';                   else                     return '<font color="red">禁用</font>';             }             },             {               "mData": 'avata',               "mRender": function ( data) {//注意，mData不为空的时候，data代表了该属性的值，可以直接使用                     return '<img class="img-rounded" src="/Uploads/'+data+'" alt="" width="75px" height="60px">';             }             },             { "mData": 'email'},             {             "mData": null,//注意，当mData为空（null）的时候data参数代表的是整个数据对象，就可以使用data.id来获取属性             "mRender": function ( data, type, full ) {                     return '<a href="#"  onClick="alert('+data.id+'); return false">修改</a>&nbsp;&nbsp;<a href="#"  onClick="alert('+data.id+'); return false">删除</a>';             }            }           ]      });
