dataTables基础函数变量

DataTable下有四个命名空间（namespace），分别是defaults，ext,models,oApi。

Defaults：主要是用于初始化表格的一些选项。

Ext：拓展项，提供额外的表格选项

Models：类模型容器，这些模型定义用于保存表的活动状态和信任的对象

oApi： 一些其他人开发的额外函数，引用插件开发人员使用的内部函数。

1个静态变量 version，3个静态方法：fnIsDataTable，fnTables，fnVersionCheck。

22个方法：

$(sSelector, oOpts) → {object}	对table的TR elemente执行jQuery选择器操作
_(sSelector, oOpts) → {array}	几乎与$完全相同
fnAddData(mData, bRedraw) → {array}     bRedraw是个bool值	向表中添加单个新行或多个行数据
fnAdjustColumnSizing(bRedraw)	这个函数使DataTabales重新计算列大小
fnClearTable(bRedraw)	快速简单的清空table
fnClose(nTr) → {int}	与“打开”opening"完全相反。这个函数将关闭当前“打开”的任何rovs。
fnDeleteRow(mTarget, fnCallBack, bRedraw) → {array}	删除表中一行
fnDestroy(bRemove)	完全从DOM中删除表。
fnDraw(bComplete)	重绘table
fnFilter(sInput, iColumn, bRegex, bSmart, bShowGlobal, bCaseInsensitive)	根据数据过滤
fnGetData(mRow, iCol) → {array|object|string}	根据提供的参数获取整个表、单个行或单元格的数据。
fnGetNodes(iRow) → {array|node}	获取表主体中使用的TR节点的数组。
fnGetPosition(nNode) → {int}	Get the array indexes of a particular cell from it's DOM element and column index including hidden columns
fnIsOpen(nTr) → {boolean}	Check to see if a row is 'open' or not.
fnOpen(nTr, mHtml, sClass) → {node}	This function will place a new row directly after a row which is currently on display on the page, with the HTML contents that is passed into the function.
fnPageChange(mAction, bRedraw) mAction   ：string | int Paging action to take: "first", "previous", "next" or "last" or page number to jump to (integer), note that page 0 is the first page.	Change the pagination - provides the internal logic for pagination in a simple API function
fnSetColumnVis(iCol, bShow, bRedraw)	Show a particular column
fnSettings() → {object}	Get the settings for a particular table for external manipulation
fnSort(iCol)	Sort the table by a particular column
fnSortListener(nNode, iColumn, fnCallback)	Attach a sort listener to an element for a given column
fnUpdate(mData, mRow, iColumn, bRedraw, bAction) → {int}	Update a table cell or row - this method will accept either a single value to update the cell with, an array of values with one element for each column or an object in the same format as the original data source.
fnVersionCheck(sVersion) → {boolean}	Provide a common method for plug-ins to check the version of DataTables being used, in order to ensure compatibility.

11个事件：

destroy	Destroy event, fired when the DataTable is destroyed by calling fnDestroy or passing the bDestroy:true parameter in the initialisation object.
draw	Draw event, fired whenever the table is redrawn on the page, at the same point as fnDrawCallback
filter	Filter event, fired when the filtering applied to the table (using the build in global global filter, or column filters) is altered.
init	DataTables initialisation complete event, fired when the table is fully drawn, including Ajax data loaded, if Ajax data is required.
page	Page change event, fired when the paging of the table is altered.
processing	Processing event, fired when DataTables is doing some kind of processing (be it, sort, filter or anything else).
sort	Sort event, fired when the sorting applied to the table is altered
stateLoaded	State loaded event, fired when state has been loaded from stored data and the settings object has been modified by the loaded data.
stateLoadParams	State load event, fired when the table is loading state from the stored data, but prior to the settings object being modified by the saved state - allowing modification of the saved state is required or loading of state for a plug-in
stateSaveParams	State save event, fired when the table has changed state a new state save is required.
xhr	Ajax (XHR) event, fired whenever an Ajax request is completed from a request to made to the server for new data

接下来在defaults命名空间下包含三个命名空间columns，oLanguage，oSearch，以及58个static properties（静态选项），主要用于初始化      的，给几个重要的看一下。

aaData :array	An array of data to use for the table, passed in at initialisation which will be used in preference to any data which is already in the DOM（就是给一些初始化数据）
aaSorting :array	You can define which column(s) the sort is performed upon, and the sorting direction, with this variable（初始化时选择排序的对象，如何排序，例如"aaSorting": [[2,'asc'], [3,'desc']]）
aLengthMenu :array	This parameter allows you to readily specify the entries in the length drop down menu that DataTables shows when pagination is enabled.（就是显示每页多少项，例如"aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]]）
bJQueryUI :boolean	Enable jQuery UI ThemeRoller support（但是需要加一些文件，目前正在研究中）
bStateSave :boolean	Enable or disable state saving. When enabled a cookie will be used to save table display information such as pagination information, display length, filtering and sorting.（这个功能挺有用的）
fnDrawCallback :function	This function is called on every 'draw' event, and allows you to dynamically modify any aspect you want about the created DOM
fnHeaderCallback :function	This function is called on every 'draw' event, and allows you to dynamically modify the header row.
fnRowCallback :function	This function allows you to 'post process' each row after it have been generated for each table draw, but before it is rendered on screen.

在defaults命名空间下的columns命名空间下又有21个static properties（静态选项），选几个重要的看一下：

aDataSort :array	Allows a column's sorting to take multiple columns into account when doing a sort.（多项配合排序时有用）
asSorting :array	You can control the default sorting direction, and even alter the behaviour of the sort handler
bSearchable :boolean，bSortable :boolean， bVisible :boolean	这三个都差不多，看变量名就应该知道它们的意思了。
mData :string|int|function|null	This property can be used to read data from any JSON data source property, including deeply nested objects / properties.
mRender :string|int|function|null	和上面一个差不多，我觉得都是非常重要的函数，如果我要在表格中插入一些标签的，比如input，a，button等，就会用到，而且挺方便的。
sClass :string，sName :string，sTitle :string，sWidth :string	基础的东西，sClass为每个td设置一个class，sName：只能在dataTable服务端使用，sTitle就是表格header，swidth：调节每个td宽度

在defaults命名空间下的oLanguage，oSearch命名空间下的变量，命名空间就不说了。

在models命名空间下又有5个namespace，分别是ext，oColumn，oRow，oSearch，oSettings。如果有人也在看datatable的doc的话，                 我非常希望有人能具体的跟我说说这个models命名空间有什么作用，我只是有一个模糊的概念。

在oApi命名空间下（Reference to internal functions for use by plug-in developers）是为了方便进行二次开发用的，有85个static methods，涵盖了defaults命名空间里所有的函数。

ext命名空间由models命名空间下的ext继承了，所以所有内容都在models/ext下。

看乱了吧，说实话我也乱了，然后我就总结了一些，画了一个思维导图
