ASP.NET揭秘读书笔记2

原来validation在这里．．

The Validation controls make use of a JavaScript script library that is automatically installed on your server when you install the .NET framework. This library is located in a file named WebUIValidation.js.

By default, WebUIValidation.js is installed in a directory named aspnet_client located beneath your Web server's wwwroot directory. If you change the location of your root directory, you need to copy the aspnet_client directory to the new directory; otherwise, the validation script will not work. If WebUIValidation.js can't be found, you receive the error Warning! Unable to find script library 'WebUIValidation.js' (see Figure 3.1).

Figure 3.1. Error from missing validation file.

NOTE

The exact location of the WebUIValidation.js file is determined by your machine.config file (in the <webControls clientScriptsLocation> section). To learn more about the machine.config file, see Chapter 15, "Creating ASP.NET Applications."

Microsoft includes a command-line tool with the ASP.NET Framework named aspnet_regiis that you can use to automatically install and uninstall the script library. To install the script library execute aspnet_regiis -c, to uninstall the library execute aspnet_regiis -e. The aspnet_regiis tool is located in your /WINNT/Microsoft.NET/Framework/[version]/directory.
