推荐答案
(document).ready(function(){{
(document).ready(function(){{
.prompt('{0}！ '，{1});}});</script>"; 字符串 message = 字符串.Format(提示，str，" {前缀:'impromptu'}"); // 在页面上注册JavaScript并使用回发控件 此 .Page.ClientScript.RegisterStartupScript( typeof (页面)，" ，消息)； } }
.prompt('{0}!',{1});}});</script>"; string message = string.Format(prompt, str, "{ prefix: 'impromptu' }"); // registering the JavaScript on the page and controls with postback this.Page.ClientScript.RegisterStartupScript(typeof(Page), "alert", message); } }

我猜想，您的脚本无法加载，原因是它们保存在"App_Data"文件夹中(Asp.net工作进程可能没有权限.在该文件夹上).要验证这一点，请将两个JQuery脚本存储在另一个文件夹中(例如，"scripts")，然后在Aspx页面中更新脚本路径.即:
I guess, your scripts are failing to load due to the fact that these are maintained within the "App_Data" folder (TheAsp.networker process may not have permission on that folder). To verify that, store the twoJQueryscripts inside a different folder (Say, "scripts") and update the script paths in theAspxpage. That is:
<script src="scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="scripts/jquery-impromptu.3.1.min.js" type="text/javascript"></script>
如果现在在页面输出中看到所需的消息，则意味着您的Asp.net工作进程缺少对"App_Data"文件夹的读取权限. (您也可以在浏览器中点击javascript的直接URL，以验证浏览器是否可以加载这些脚本).如果是这样，则需要为工作进程(或运行Asp.net应用程序的用户帐户)分配足够的权限，并确保浏览器可以在URL中加载这些脚本.这应该可以解决您的问题.
If you see the desired message in the page output now, that means, your Asp.net worker process lacks enough read permission on the "App_Data" folder. (You can also hit a direct URL of the javascripts in the browser to verify whether browser can load these scripts). If that is so, you need to assign enough permission on the worker process (Or, on the user account under which the Asp.net application is running) and make sure that your browser can load those scripts in the URL. This should solve your problem.
