创建一个MVC项目，它的“脚本”文件夹将包含MicrosoftAjax.js (发行版和调试版)。

至少在Visual Web Developer 2008速成版中，scripts文件夹不包含任何全球化脚本，即为该区域性定义和设置“__cultureInfo”的205个文件(例如"af-ZA.js")。

在MVC项目模板Zip文件中也缺少它们。

我想你可以分开下载，但是...

在MsAjax的__cultureInfo针对浏览器首选语言进行定制的情况下，实现脚本全球化的MVC方法是什么？

ajax

asp.net-mvc

scripting

globalization

好的..。好吧..。事实证明你必须自己去做。

下面的代码告诉您如何获取和安装全球化脚本。此外，它还为您提供了一个方便的扩展方法，允许您在启用或不启用脚本全球化的情况下，在视图或母版页上注入对MS AJAX的引用。

特点：-

enable script globalization

optionally inject call

Sys.Application.initialize() function

optionally

inline

Sys.Application.initialize()inline inline用于启用脚本全球化的代码(需要条件编译符号)；默认情况下，将注入全球化脚本文件的引用。

<代码>F215

享受吧！

// 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.

我们已经在CDN上发布了更新的全球化脚本。这篇博文将带你了解如何利用globalization with ASP.NET MVC client validation。
