下面一段代码是关于datatable增加跳转到指定页功能，具体代码如下所示：
var mytable = $('#datatables'); mytable.dataTable( { "sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>", "sPaginationType": "bootstrap", "bProcessing": true, "bServerSide": true, "sAjaxSource": "/user/list", "aoColumns": [ { "mData": "Id" }, { "mData": "Username" }, {"mData":function(obj){ return obj.group; }}, {"mData":"yiyuan"}, {"mData":function(obj){ return obj.keshi; }}, {"mData":function(obj){ if(obj.Status==1){ return "使用中"; }else{ return "禁用"; } }}, {"mData": function(obj){ var del=""; if(isAdmin){ del='<a data-title="' + obj.Id + '"><i ></i>删除</a>'; } return '<a data-title="' + obj.Id + '" href="#" ><i></i>修改</a>' +' '+del; },bSortable : false} ], "fnDrawCallback": function(){ var oTable = $("#datatables").dataTable(); $('#redirect').keyup(function(e){ if($(this).val() && $(this).val()>0){ var redirectpage = $(this).val()-1; }else{ var redirectpage = 0; } oTable.fnPageChange( redirectpage ); }); } }); bootstrap插件形式： /* Set the defaults for DataTables initialisation */ $.extend( true, $.fn.dataTable.defaults, { "sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>", "sPaginationType": "bootstrap", "oLanguage": { "sSearch": "快速搜索:", "bAutoWidth": true, "sLengthMenu": "每页显示 _MENU_ 条记录", "sZeroRecords": "Nothing found - 没有记录", "sInfo": "_START_ 到 _END_ 条,共 _TOTAL_ 条", "sInfoEmpty": "显示0条记录", "sInfoFiltered": "(从 _MAX_ 条中过滤)", "sProcessing":"<div><img src='https://www.jb51.net/static/img/loader.gif'><span>加载中...</span></div>", "oPaginate": { "sPrevious": "", "sNext": "", "sLast": ">>", "sFirst": "<<" } } } ); /* Default class modification */ $.extend( $.fn.dataTableExt.oStdClasses, { "sWrapper": "dataTables_wrapper form-inline" } ); /* API method to get paging information */ $.fn.dataTableExt.oApi.fnPagingInfo = function ( oSettings ) { return { "iStart": oSettings._iDisplayStart, "iEnd": oSettings.fnDisplayEnd(), "iLength": oSettings._iDisplayLength, "iTotal": oSettings.fnRecordsTotal(), "iFilteredTotal": oSettings.fnRecordsDisplay(), "iPage": Math.ceil( oSettings._iDisplayStart / oSettings._iDisplayLength ), "iTotalPages": Math.ceil( oSettings.fnRecordsDisplay() / oSettings._iDisplayLength ) }; }; /* Bootstrap style pagination control */ $.extend( $.fn.dataTableExt.oPagination, { "bootstrap": { "fnInit": function( oSettings, nPaging, fnDraw ) { var oLang = oSettings.oLanguage.oPaginate; var fnClickHandler = function ( e ) { e.preventDefault(); if ( oSettings.oApi._fnPageChange(oSettings, e.data.action) ) { fnDraw( oSettings ); } }; $(nPaging).addClass('pagination').append( '<ul>'+ '<li><a href="#" >'+oLang.sFirst+'</a></li>'+ '<li><a href="#" >← '+oLang.sPrevious+'</a></li>'+ '<li><a href="#" >'+oLang.sNext+' → </a></li>'+ '<li><a href="#" >'+oLang.sLast+'</a></li>'+ '<input type="text">'+ '</ul>' ); //datatables分页跳转 $(nPaging).find(".redirect").keyup(function(e){ var ipage = parseInt($(this).val()); var oPaging = oSettings.oInstance.fnPagingInfo(); if(isNaN(ipage) || ipage<1){ ipage = 1; }else if(ipage>oPaging.iTotalPages){ ipage=oPaging.iTotalPages; } $(this).val(ipage); ipage--; oSettings._iDisplayStart = ipage * oPaging.iLength; fnDraw( oSettings ); }); var els = $('a', nPaging); $(els[0]).bind( 'click.DT', { action: "first" }, fnClickHandler ); $(els[1]).bind( 'click.DT', { action: "previous" }, fnClickHandler ); $(els[2]).bind( 'click.DT', { action: "next" }, fnClickHandler ); $(els[3]).bind( 'click.DT', { action: "last" }, fnClickHandler ); }, "fnUpdate": function ( oSettings, fnDraw ) { var iListLength = 5; var oPaging = oSettings.oInstance.fnPagingInfo(); var an = oSettings.aanFeatures.p; var i, ien, j, sClass, iStart, iEnd, iHalf=Math.floor(iListLength/2); if ( oPaging.iTotalPages < iListLength) { iStart = 1; iEnd = oPaging.iTotalPages; } else if ( oPaging.iPage <= iHalf ) { iStart = 1; iEnd = iListLength; } else if ( oPaging.iPage >= (oPaging.iTotalPages-iHalf) ) { iStart = oPaging.iTotalPages - iListLength + 1; iEnd = oPaging.iTotalPages; } else { iStart = oPaging.iPage - iHalf + 1; iEnd = iStart + iListLength - 1; } for ( i=0, ien=an.length ; i<ien ; i++ ) { // Remove the middle elements ($('li:gt(1)', an[i]).filter(':not(:last)')).filter(':not(:last)').remove(); // Add the new list items and their event handlers for ( j=iStart ; j<=iEnd ; j++ ) { sClass = (j==oPaging.iPage+1) ?
