推荐答案
问题是由该JScript1.js文件存储在浏览器高速缓存中的事实而引起的。你运行应用程序时，都会在文件的缓存版本是用来代替目前的版本。例如，如果你改变了code表示：
The problem is caused by the fact that the JScript1.js file is stored in the browser cache. Every time you run the application, the cached version of the file is used instead of the current version. For example, if you change the code for:
function notify() {
alert('Notify 2');
}
和再次运行应用程序，你不会看到这个新的消息，除非你清除浏览器缓存（或如果浏览器被设置为自动清除它）。
and run your application again, you will not see this new message unless you clear your browser cache (or if the browser is set to clear it automatically).
您可以强制浏览器每个应用程序启动时附加一个不同的查询字符串的文件名来加载新的JavaScript文件：
You can force the browser to load the new Javascript file by appending a different query string to the file name each time the application starts:
<script type="text/javascript" src="JScript1.js?<%# DateTime.Now.Ticks.ToString() %>"></script>
在实际应用中，它是preferable强制浏览器下载JScript1.js只有当它的内容已被修改。这可以通过附加的文件版本的文件名（代替一个时间刻度计数）来完成。该脚本报关行看起来是这样的：
In real world applications, it is preferable to force the browser to download JScript1.js only when its content has been modified. This can be done by appending the file version to the file name (instead of a time tick count). The script declaration line could look like this:
<script type="text/javascript" src="JScript1.js?version=<%# AppVersion %>"></script>
这将使用定义的AppVersion属性code-背后：
which would use an AppVersion property defined in code-behind:
public string AppVersion
{
get
{
return System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();
}
}
大会文件的版本应该再被更新（在项目的属性），当变化JScript1.js而成。
The version of the assembly file should then be updated (in the properties of the project) when a change is made in JScript1.js.
