摘要：是一款表格插件。當你打開服務(wù)器模式的時候，每次繪制表格的時候，會給服務(wù)器發(fā)送一個請求包括當前分頁，排序，搜索參數(shù)等等。開啟服務(wù)器模式需要使用和不定時一講選項，進一步的信息，請參考下面的配置選項。
一、簡單使用Datatables 是一款jquery表格插件。它是一個高度靈活的工具，可以將任何HTML表格添加高級的交互功能，可以很方便的實現(xiàn)分頁，即時搜索和排序。
怎樣簡單地使用DataTables？使用下方簡單的幾行代碼，一個方法初始化table。
$(document).ready(function(){
$("#myTable").DataTable();
});
開始使用DataTables很簡單，只需要引入兩個文件， 一個css樣式文件和DataTables本身的腳本文件。在DataTables CDN上，可以使用下面這兩個文件：
http://cdn.datatables.net/1.10.15/css/jquery.dataTables.min.css http://cdn.datatables.net/1.10.15/js/jquery.dataTables.min.js二、選項
datatables中大量的選項可以用來定制你的表格展現(xiàn)給用戶。
1. 設(shè)置選項(Setting options)datatables的配置是通過設(shè)置你定義的選項來完成的，如下：
$("#example").DataTable( {
paging: false
} );
通過設(shè)置paging選項，禁止表格分頁(默認是打開的)
假設(shè)你要在表格里使用滾動，你需要加上scrollY選項：
$("#example").DataTable( {
scrollY: 400
} );
當然你可以組合多個選項來初始化datatables，啟動滾動條，禁用分頁
$("#example").DataTable( {
paging: false,
scrollY: 400
} );
如果你有其他需要可以加入更多的選項來配置你的表格，更多datatables選項，請參考
常用選項(Common options)
下面列舉了一些比較有用的選項:
ajax - 異步數(shù)據(jù)源配置 data - javascript數(shù)據(jù)源配置 serverSide - 開啟服務(wù)器模式 columns.data - 配置每一列的數(shù)據(jù)源 scrollX - 水平滾動條 scrollY - 垂直滾動條 默認設(shè)置(Setting defaults)
在實際項目中，可能需要用到多個表格，你使用dom選項把所有的表格設(shè)置為相同的布局，這時你可以使用$.fn.dataTable.defaults 對象處理。
在這個例子中,我們禁用datatable中默認的搜索和排序功能,但當表初始化時啟用了排序(重寫默認選項)。
// 默認禁用搜索和排序
$.extend( $.fn.dataTable.defaults, {
searching: false,
ordering: false
} );
// 這樣初始化，排序?qū)蜷_
// 搜索功能仍然是關(guān)閉
$("#example").DataTable( {
ordering: true
} );

三、服務(wù)器處理(Server-side processing)服務(wù)器處理
是不是發(fā)現(xiàn)在處理太多 DOM 數(shù)據(jù)或者 AJAX 一次性把數(shù)據(jù)獲得后，DataTables 表現(xiàn)的不是很滿意？這是肯定的， 因為 DT 需要渲染，創(chuàng)建 tr/td ,所以數(shù)據(jù)越多，速度就越慢。 為了解決這個問題 DataTables 提供了 服務(wù)器模式，把本來客戶端所做的事情交給服務(wù)器去處理， 比如排序（order）、分頁（paging）、過濾（filter）。對于客戶端來說這些操作都是比較消耗資源的， 所以打開服務(wù)器模式后不用擔心這些操作會影響到用戶體驗。
當你打開服務(wù)器模式的時候，每次繪制表格的時候，DataTables 會給服務(wù)器發(fā)送一個請求（包括當前分頁，排序，搜索參數(shù)等等）。DataTables 會向 服務(wù)器發(fā)送 一些參數(shù) 去執(zhí)行所需要的處理，然后在服務(wù)器組裝好 相應(yīng)的數(shù)據(jù) 返回給 DataTables。
開啟服務(wù)器模式需要使用 serverSideOption 和 ajaxOption ajax不定時一講 選項，進一步的信息，請參考下面的 配置選項。
1、DT自動請求的參數(shù)(Sent parameters)當開啟了 服務(wù)器模式時，DataTables 會發(fā)送如下參數(shù)到服務(wù)器
一旦 DataTables 發(fā)送了請求，上面的參數(shù)就會傳送給服務(wù)器，那么你需要接受到這些參數(shù)并做相應(yīng)的邏輯處理然后按照下面的格式講組裝好的JSON數(shù)據(jù)返回 （不是每個參數(shù)都需要接受處理，根據(jù)自己的業(yè)務(wù)需要）
除了上面的返回參數(shù)以外你還可以加入下面的參數(shù)，來實現(xiàn)對表格數(shù)據(jù)的自動綁定
