我试图通过javascript警告框显示异常消息.
这是示例代码.
public static void HandleException(Page page, Exception ex)
{
string message = ex.Message.ToString();
ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "", "alert('"+message+"');", true);
}
如果我给字符串变量提供文字值,它就会运行.例如
string message = "Hello World";
但如果我给message = ex.Message,它就会失败;
任何的想法？

参考这个答案,我尝试使用命令增加缓冲区大小
set-option -g history-limit 10000
set -g history-limit 10000
但它对我不起作用.我想增加所有窗口的缓冲区大小或至少增加tmux中的当前窗口.我在Putty打开tmux会话.
注意:我试图使用鼠标滚动.我能够使用"前缀["但不使用鼠标向上滚动

提前致谢.
1)我怎么能一个符号转换成它的4位数Unicode转义表示在Python 2.7如"¥"要"\u00a5"？
2)我如何转换为Unicode表示在Windows平台上7/8例如象征符号"\u00a5"来"¥"？
我想以相反的顺序在UITableView中显示数据.我设法用很少的努力去做,但任何人都可以提供更好的方法.提前致谢.
哪个是开发跨平台应用程序的最佳框架.特别是对于Android和iPhone.我已经通过互联网上的评论,但那些似乎已经很老了.我相信Titanium和Rhodes在过去几年里都发展得很好.
我想创建3个div,使整个页面的大小与窗口大小相同(即页面不应滚动),每个div的高度应为整个高度的百分之几.例如
|--------------------------------------|
| Body height=window's height |
| |----------------------------------| |
| | Header height:10% | |
| |----------------------------------| |
| | | |
| | Content height:85% | |
| | | |
| | | |
| |----------------------------------| |
| | Footer height:5 % | |
| |----------------------------------| |
|--------------------------------------|
这是我使用的代码没有任何成功
<body style="width: 100%; height:100%">
<div style="width: 100%; height:100%;">
<div id="headerDiv" style="width: 100%; height:10%; background-color: #ff0000">
<!-- some content -->
</div>
<div style="width: 100%; height:85%;" >
