上周因为需要使用了datatable,可是网上搜索到的要么就是一点点的参数介绍,要么就是几个回调函数的介绍,极少数有比较全面的,所以把自己用到的总结了一下,这其中涉及到服务端的分页,其实datatable都给我们集成好了,用起来是很方便的,话不多说,如下:
关于datatable使用详解:
1、基本参数配置:
要注意的是,要被dataTable处理的table对象,必须有thead与tbody,而且,结构要规整(数据不一定要完整),这样才能正确处理。以下是在进行dataTable绑定处理时候可以附加的参数:

属性名称取值范围解释bAutoWidthtrue or false, default true是否自动计算表格各列宽度bDeferRendertrue or false, default false用于渲染的一个参数bFiltertrue or false, default true开关,是否启用客户端过滤功能bInfotrue or false, default true开关,是否显示表格的一些信息bJQueryUItrue or false, default false是否使用jquery ui themeroller的风格bLengthChangetrue or false, default true开关,是否显示一个每页长度的选择条(需要分页器支持)bPaginatetrue or false, default true开关,是否显示(使用)分页器bProcessingtrue or false, defualt false开关,以指定当正在处理数据的时候,是否显示“正在处理”这个提示信息bScrollInfinitetrue or false, default false开关,以指定是否无限滚动(与sScrollY配合使用),在大数据量的时候很有用。当这个标志为true的时候,分页器就默认关闭bSorttrue or false, default true开关,是否让各列具有按列排序功能bSortClassestrue or false, default true开关,指定当当前列在排序时,是否增加classes 'sorting_1', 'sorting_2' and 'sorting_3',打开后,在处理大数据时,性能有所损失bStateSavetrue or false, default false开关,是否打开客户端状态记录功能。这个数据是记录在cookies中的,打开了这个记录后,即使刷新一次页面,或重新打开浏览器,之前的状态都是保存下来的sScrollX'disabled' or '100%' 类似的字符串是否开启水平滚动,以及指定滚动区域大小sScrollY'disabled' or '200px' 类似的字符串是否开启垂直滚动,以及指定滚动区域大小------选项  aaSortingarray array[int,string], 如[], [[0,'asc'], [0,'desc']]指定按多列数据排序的依据aaSortingFixed同上同上。唯一不同点是不能被用户的自定义配置冲突aLengthMenudefault [10, 25, 50, 100],可以为一维数组,也可为二维数组,比如:[[10, 25, 50, -1], [10, 25, 50, "All"]]这个为选择每页的条目数,当使用一个二维数组时,二维层面只能有两个元素,第一个为显示每页条目数的选项,第二个是关于这些选项的解释aoSearchColsdefault null, 类似:[null, {"sSearch": "My filter"}, null,{"sSearch": "^[0-9]", "bEscapeRegex": false}]给每个列单独定义其初始化搜索列表特性(这一块还没搞懂)asStripClassesdefault ['odd', 'even'], 比如['strip1', 'strip2', 'strip3']指定要被应用到各行的class风格,会自动循环bDestroytrue or false, default false用于当要在同一个元素上执行新的dataTable绑定时,将之前的那个数据对象清除掉,换以新的对象设置bRetrievetrue or false, default false用于指明当执行dataTable绑定时,是否返回DataTable对象bScrollCollapsetrue or false, default false指定适当的时候缩起滚动视图bSortCellsToptrue or false, default false(未知的东东)iCookieDuration整数,默认7200,单位为秒指定用于存储客户端信息到cookie中的时间长度,超过这个时间后,自动过期iDeferLoading整数,默认为null延迟加载,它的参数为要加载条目的数目,通常与bServerSide,sAjaxSource等配合使用iDisplayLength整数,默认为10用于指定一屏显示的条数,需开启分页器iDisplayStart整数,默认为0用于指定从哪一条数据开始显示到表格中去iScrollLoadGap整数,默认为100用于指定当DataTable设置为滚动时,最多可以一屏显示多少条数据oSearch默认{ "sSearch": "", "bRegex": false, "bSmart": true }又是初始时指定搜索参数相关的,有点复杂,没搞懂目前sAjaxDataProp字符串,default 'aaData'指定当从服务端获取表格数据时,数据项使用的名字sAjaxSourceURL字符串,default null指定要从哪个URL获取数据sCookiePrefix字符串,default 'SpryMedia_DataTables_'当打开状态存储特性后,用于指定存储在cookies中的字符串的前缀名字sDomdefault lfrtip (when bJQueryUI is false) or <"H"lfr>t<"F"ip> (when bJQueryUI is true)这是用于定义DataTable布局的一个强大的属性,另开专门文档来补充说明吧sPaginationType'full_numbers' or 'two_button', default 'two_button'用于指定分页器风格sScrollXInnerstring default 'disabled'又是水平滚动相关的,没搞懂啥意思


对于服务器来说,可以通过请求参数来获得当前的操作信息。[也就是说以下这个列表中的属性值都是可以在服务器端的方法中获取到!]这些在下面的例子中aodata中都可以获取得到

类型名称说明intiDisplayStart显示的起始索引intiDisplayLength显示的行数intiColumns显示的列数stringsSearch全局搜索字段booleanbEscapeRegex全局搜索是否正则booleanbSortable_(int)表示一列是否在客户端被标志位可排序booleanbSearchable_(int)表示一列是否在客户端被标志位可搜索stringsSearch_(int)个别列的搜索booleanbEscapeRegex_(int)个别列是否使用正则搜索intiSortingCols排序的列数intiSortCol_(int)被排序的列stringsSortDir_(int)排序的方向 "desc" 或者 "asc".stringsEchoDataTables 用来生成的信息

 
服务器返回的数据格式如下所示类型名称说明intiTotalRecords实际的行数intiTotalDisplayRecords过滤之后,实际的行数。stringsEcho来自客户端 sEcho 的没有变化的复制品,stringsColumns可选,以逗号分隔的列名,array array mixedaaData数组的数组,表格中的实际数据。
 

回调函数名称参数返回值默认功能fnCookieCallback1.string: Name of the cookie defined by DataTables 2.object: Data to be stored in the cookie 3.string: Cookie expires string 4.string: Path of the cookie to setstring: cookie formatted string (which should be encoded by using encodeURIComponent())null当每次cookies改变时,会触发这个函数调用fnDrawCallback无无无在每次table被draw完后调用,至于做什么就看着办吧fnFooterCallback1.node : "TR" element for the footer 2.array array strings : Full table data (as derived from the original HTML) 3.int : Index for the current display starting point in the display array< 4.int : Index for the current display ending point in the display array 5.array int : Index array to translate the visual position to the full data array无无用于在每次重画的时候修改表格的脚部fnFormatNumber1.int : number to be formattedString : formatted string for DataTables to show the number有默认的用于在大数字上,自动加入一些逗号,分隔开fnHeaderCallback1.node : "TR" element for the header 2.array array strings : Full table data (as derived from the original HTML) 3.int : Index for the current display starting point in the display array 4.int : Index for the current display ending point in the display array 5.array int : Index array to translate the visual position to the full data array无无用于在每次draw发生时,修改table的headerfnInfoCallback1.object: DataTables settings object 2.int: Starting position in data for the draw 3.int: End position in data for the draw 4.int: Total number of rows in the table (regardless of filtering) 5.int: Total number of rows in the data set, after filtering 6.string: The string that DataTables has formatted using it's own rulesstring: The string to be displayed in the information element.无用于传达table信息fnInitComplete1.object:oSettings - DataTables settings object无无表格初始化完成后调用fnPreDrawCallback1.object:oSettings - DataTables settings objectBoolean无用于在开始绘制之前调用,返回false的话,会阻止draw事件发生;返回其它值,draw可以顺利执行fnRowCallback1.node : "TR" element for the current row 2.array strings : Raw data array for this row (as derived from the original HTML) 3.int : The display index for the current table draw 4.int : The index of the data in the full list of rows (after filtering)node : "TR" element for the current row无当创建了行,但还未绘制到屏幕上的时候调用,通常用于改变行的class风格fnServerData1.string: HTTP source to obtain the data from (i.e. sAjaxSource) 2.array objects: A key/value pair object containing the data to send to the server 3.function: Function to be called on completion of the data get process that will draw the data on the page.void$.getJSON用于替换默认发到服务端的请求操作fnStateLoadCallback1.object:oSettings - DataTables settings object 2.object:oData - Object containing information retrieved from the state saving cookie which should be restored. For the exact properties please refer to the DataTables code.Boolean - false if the state should not be loaded, true otherwise无在cookies中的数据被加载前执行,可以方便地修改这些数据fnStateSaveCallback1.object:oSettings - DataTables settings object 2.String:sValue - a JSON string (without the final closing brace) which should be stored in the state saving cookie.String - the full string that should be used to save the state无在状态数据被存储到cookies前执行,可以方便地做一些预操作



其中,涉及到服务器端分页的地方还需要实例来解释:
$("#" + tableId).dataTable({    "aLengthMenu": [10,15,20], //更改显示记录数选项"bAutoWidth": true, //是否自适应宽度"bFilter": false,"columns": [{"data": "id","sDefaultContent": "", //此列默认值为"",以防数据中没有此值,DataTables加载数据的时候报错"bVisible": false //此列不显示},{"data": "CallCount","sTitle": "访问次数","sClass": "left"},{"data": "update","sTitle": "编辑","sClass": "left"}],"oLanguage": { //国际化配置"sProcessing": "正在获取数据,请稍后...","sLengthMenu": "显示 _MENU_ 条","sZeroRecords": "没有您要搜索的内容","sInfo": "从 _START_ 到 _END_ 条记录 总记录数为 _TOTAL_ 条","sInfoEmpty": "记录数为0","sInfoFiltered": "(全部记录数 _TOTAL_ 条)","sInfoPostFix": "","sSearch": "搜索","sUrl": "","oPaginate": {"sFirst": "第一页","sPrevious": "上一页","sNext": "下一页","sLast": "最后一页"}},//fnInitComplete:当datatable初始化完成之后,我显示了我自己添加的日期的搜索,以及审核按钮,主要目的是用户体验优化"fnInitComplete": function () {$('#time_select').css("display", "inline-block");$('#audit_pass').css("display", "inline-block");},"bProcessing": false, //是否显示加载"sAjaxSource": '/admin/Developer/getDeveloperData', //请求资源路径"serverSide": true, //开启服务器处理模式"fnDrawCallback":function(){//修改事件$('.update-span').click(function () {var oTable = $('#'+tableId).dataTable();var b = oTable.fnGetData($(this).parent().parent());$('#son_form').css('display', 'block');addFormData(b);});},"fnServerParams": function (aoData) {aoData.push({ "name": "status", "value": $('#audit').val() });aoData.push({ "name": "beginTime", "value": $('#start_date').val() });aoData.push({ "name": "endTime", "value": $('#end_date').val() });},"fnServerData": function (sSource, aoData, fnCallback) {$.ajax({'type': 'post',"url": sSource,"dataType": "json","data": { 'aoData': JSON.stringify(aoData) },//"aodata": JSON.stringify(aoData)"success": function (resp) {var msgJson = new Object();msgJson = packagingdatatabledata(resp);var msgString = JSON.stringify(msgJson);var a = eval('(' + msgString + ')');fnCallback(a);}});}});


而在我自己的事件请求中,可以直接调用datatable的方法完成页面的重绘

$.ajax({type: 'post',//可选geturl: '/admin/Developer/checkData',data: { 'user_Id': JSON.stringify(a) },dataType: 'json',//服务器返回的数据类型 可选XML ,Json jsonp script htmltext等success: function (msg) {$('#' + tableId).dataTable().fnDraw();},error: function () {}});


对datatable()进行输出以后,可以发现这些

fnDraw:(a)
fnFilter:(a,b,c,e,d,h)

随便找一个试试,果然是的
再找一个验证一下
OK
