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":"<div style=''><img src='../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 class="first disabled"><a href="#">'+oLang.sFirst+'</a></li>'+
'<li class="prev disabled"><a href="#">'+oLang.sPrevious+'</a></li>'+
'<li class="next disabled"><a href="#">'+oLang.sNext+'</a></li>'+
'<li class="last disabled"><a href="#">'+oLang.sLast+'</a></li>'+
'<input type="text"id="redirect"class="redirect">'+
'</ul>'
);
//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);
timer = setTimeout(function(){fnDraw( oSettings);
},600);
});
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) ? 'class="active"':'';
$('<li'+sClass+'><a href="#">'+j+'</a></li>')
.insertBefore($('.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
$.extend( true, $.fn.DataTable.TableTools.classes, {
"container": "DTTT btn-group",
