datatables增加跳轉指定頁功能, datatable自定義分頁

DataTable使用方便，快捷。但有時候使用者需求對分頁有需求，例如輸入頁數進行分頁跳轉。
這樣就需要擴充套件功能了，datatable也支援自定義擴充套件，下面以使用DataTable bootstrap分頁為例
1. 初始化DataTable
var $table = $('#listTable');
var listTable = $table.DataTable({
language: { url: path + '/resources/js/bootstrap/dtChinese.json' },
searching: false, //搜尋欄
ordering: true, //排序
scrollX: true,
scrollY: scrollY,//表格滾動區高度
columns: columns,
serverSide: true, //開啟後臺分頁
processing: true, //開啟資料載入時的等待效果
lengthChange: false, //禁用每頁顯示的記錄數
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. 擴充套件功能
DataTable自定義分頁（bootstrap分頁）擴充套件程式碼如下
/* 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>>",

"bAutoWidth": true,
"sLengthMenu": "每頁顯示 _MENU_ 條記錄",
"sZeroRecords": "Nothing found - 沒有記錄",
"sInfo": "_START_ 到 _END_ 條,共 _TOTAL_ 條",
"sInfoEmpty": "顯示0條記錄",
"sInfoFiltered": "(從 _MAX_ 條中過濾)",
// "sProcessing":"<div style=''><img src='../static/img/loader.gif'><span>載入中...</span></div>",
"oPaginate": {
"sPrevious": "",
"sNext":"",
"sLast":">>",

}
}
} );
