好的......好的......事實證明你必須自己動手。
以下代碼告訴您如何獲取全球化腳本並進行安裝。此外,它還爲您提供了一種便捷的擴展方法,允許您在View或Master Page上注入MS AJAX參考,並啓用或不啓用腳本全球化。
特點: -
- 注入MS AJAX到查看以最小的努力
- 調試或發佈版本根據組件是否 編譯在調試或發佈模式選擇
- 任選使腳本全球化
- 可選地向Sys.Application.initialize()函數注入調用
- 可選內聯啓用腳本全球化的代碼,如ScriptManager所做的 (需要條件編譯符號);默認情況下參考到注入全球化腳本文件。
享受!

// Include Microsoft Ajax In Your ASP.NET MVC Projects, Optionally With Script Globalization Enabled
// -------------------------------------------------------------------------------------------------
//
// Written by Andrew Webb, 4th May 2009.
//
// Feel free to use in your ASP.NET MVC projects.
// Written for ASP.NET MVC 1.0 and .NET Framework 3.5 SP1.
//
// With thanks to Bertrand LeRoy and Steven Sanderson.
// http://weblogs.asp.net/bleroy/
// http://blog.codeville.net/
//
// Example usage of 'IncludeMicrosoftAjax':-
// <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" Culture="auto" UICulture="auto" %>
// <%@ Import Namespace="AspNetMvcHelper" %>
// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
// <html xmlns="http://www.w3.org/1999/xhtml" >
// <head runat="server">
// <!-- Include Ms Ajax, with script globalization enabled -->
// <%= Html.IncludeMicrosoftAjax (true, false) %>
// <!-- other script references here, e.g. jQuery -->
// </head>
// etc.
//
// Note: for script globalization, the method in this file gets the current thread's current culture.
// The Culture="auto" setting in the Page directive (above) causes this to be set to the browser's
// preferred language. Alternatively you can set the current thread's current culture manually.
//
// NOTA BENE: for script globalization, the 205 globalization scripts from the MS AJAX Library must be
// obtained from Microsoft and added to your ASP.NET MVC project, as follows:
// 1) Download the Microsoft AJAX Library 3.5 from:
// http://www.asp.net/ajax/downloads/
//
// 2) Extract all files from the Zip, and locate the "Globalization" folder. It should have 205 script files
// in it, from "af-ZA.js" to "zu-ZA.js". Copy this folder inside your website/project, under the "Scripts"
// folder. Rename the folder to "MsAjaxGlobalization". The resulting structure should be:
// <project>\
// Scripts\
// MsAjaxGlobalization\
// <205 files>
// <jQuery, Ms Ajax and Ms Mvc Ajax files>
//
// Be sure to include the "MsAjaxGlobalization" folder in your web project. The easiest way is to click
// "Show All Files" button in the Solution Explorer's toolbar so that all files are shown, then right-click
// on "MsAjaxGlobalization" folder and select 'Include In Project' menu item. You can now unshow all files
// again.
