DataTable使用方便，快捷。但有时候用户需求对分页有需求，例如输入页数进行分页跳转。
这样就需要扩展功能了，datatable也支持自定义扩展，下面以使用DataTable bootstrap分页为例
1. 初始化DataTable
var $table = $('#listTable');
var listTable = $table.DataTable({
language: { url: path + '/resources/js/bootstrap/dtChinese.json' },
searching: false, //搜索栏
ordering: true, //排序
scrollX: true,
scrollY: scrollY, //表格滚动区高度
columns: columns,
serverSide: true, //打开后台分页
processing: true, //打开数据加载时的等待效果
lengthChange: false, //禁用每页显示的记录数
sPaginationType: "bootstrap", //bootstrap / full_numbers
// lengthMenu: [
// [20, 50, 100, -1],
// [20, 50, 100, "All"]
// ],
pageLength: 20,
ajax: path + '/searchBase?name=' + sqlStr + '&type=getSqlValues&dataBase=' + opt.dataBase
});2. 扩展功能
DataTable自定义分页（bootstrap分页）扩展代码如下
/* 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":"
加载中...",
"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(
''+
'- '+oLang.sFirst+'
'+
'- '+oLang.sPrevious+'
'+
'- '+oLang.sNext+'
'+
'- '+oLang.sLast+'
'+
''+
'
'
);
//datatables分页跳转
$(nPaging).find(".redirect").keyup(function(e){
var ipage = parseInt($(this).val());
var oPaging = oSettings.oInstance.fnPagingInfo();
var timer = null;
if(isNaN(ipage) || ipage<1){
ipage = 1;
}else if(ipage>oPaging.iTotalPages){
ipage=oPaging.iTotalPages;
}
$(this).val(ipage);
ipage--;
oSettings._iDisplayStart = ipage * oPaging.iLength;
clearTimeout(timer);

fnDraw( oSettings );
},600);
});

},

}
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'+j+'')
.insertBefore( $('.next', an[i])[0] )
.bind('click', function (e) {
e.preventDefault();
oSettings._iDisplayStart = (parseInt($('a', this).text(),10)-1) * oPaging.iLength;
fnDraw( oSettings );
} );
}
// Add / remove disabled classes from the static elements
if ( oPaging.iPage === 0 ) {
$('li:lt(2)', an[i]).addClass('disabled');
} else {
$('li:lt(2)', an[i]).removeClass('disabled');
}
if ( oPaging.iPage === oPaging.iTotalPages-1 || oPaging.iTotalPages === 0 ) {
$('.next', an[i]).addClass('disabled');
$('li:last', an[i]).addClass('disabled');
} else {
$('.next', an[i]).removeClass('disabled');
$('li:last', an[i]).removeClass('disabled');
}
}
}
}
} );
/*

if ( $.fn.DataTable.TableTools ) {
// Set the classes that TableTools uses to something suitable for Bootstrap
