不好意思,老问题。

“iPad charger output is 5.1Volts, 2.1Amp. iPhone charger output is 5Volt,
1Amp. So the iPad charger is a higher output voltage, but only 2% higher.
These are what's written on them, I've not put a meter to them to verify.

还是可以读取value,一个loop就可以了。
也根本不用假设有且只有多少个hidden,取length就可以。
要找某个input出来,通过parent或者sibling的id或name或class都可以。
在这点上type=hidden其实跟设成readonly是差不多的。
你转换出来的这个问题,其实是强行多选一。
实际情况里,如果需要设置一个不用name或者id的input,很容易选,而如果设置多个
不用name或者id的input,那么必然也是对每个element都进行某种操作。所以技术上
不存在困难。事实上,页面总有其它element存在,所以挑出某一个input总是可以做到
的。即使页面上没有任何其它element存在,用下标操作也是适合某些business logic
的,比如表格。如果一个表格的每个cell里有几个input,包括一个hidden的。这样确实
没有必要给id或者name,因为给的id或者name也就是下标,直接用dom操作表格就可以
找到想要的hidden input了。

来自主题: CS版 - 问个VBA的问题
我用VBA写macro的时候,遇到了这个问题。在run这一行的时候:
dailyDS.SaveAs fileName:= _
outPath, FileFormat:=xlNormal, _
Password:="", WriteResPassword:="", ReadOnlyRecommended:=True, _
CreateBackup:=False
有可能出错,也有可能通过了。
outPath是一个ftp地址,包括了用户名和密码,这个用户名和密码肯定能够登陆的。
错误信息就是Runtime error 1004. Method ’SaveAs’ of object ’_Workbook’
failed.
出错以后如果选择debug,continue,这一行就可以通过。
如果一开始在这一行设了断点,手动continue,也没错,可以通过。
如果不出错的话,存下来的文件确实是readonly的。这个比较关键,因为我如果saveas
到本地的话,用bat文件也可以ftp到需要的地点,不过那样ft

this is normally because when u use Access2000 to open a mdb file created
by older version of Access, it will be ReadOnly. try converting the mdb

JUST BROWSE, NO ACCOUNT CREATION,NO SIGN UP
这个READONLY,接IN-MEMROY DATABASE,自己去玩了
ASK QUESTIONS/HELP ->CHAT 或者打电话,直奔CALL CENTER
INTEREST IN SIGN UP -》马上要求CREATE ACCOUNT,姓名等+SSN,BFFORE SHOW ANY

很多人可能知难而退了,SAVE退出。输入INCOME等具体信息完毕后,SHOW PLAN 和价格,
要求SIGN UP
SIGN UP NOW OR CONTINUE SIGN UP
这个是SERIOUS的,完成PROFILE SHOW PLAN和价格,SIGN UP

来自主题: DotNet版 - C# interview question
When you use const, it has to be known by compilation time.
readonly is better, you want to assign the size in initilization.
That size is determined at runtime.

谢谢, 我用的c++, 没用过c#, c++也有readonly吗? 难道是因为
大家都用一个.net环境? 觉得不会呀.
我把源码放在ftp上面, static和enum两个版本, 你们有兴趣
可以看一下其中static定义部分, 并用.net编译一下.
没空就不麻烦了. 我只是奇怪.net 2003 c++的编译器怎么
会不能识别static const unsigned int DEFAULT_CAPACITY = 30;

MSDN 说得很清楚了,static const不能一起用,static readonly可以。和和。
C++也有这个,我查的vs.net 2003带的msdn,你难道不用msdn么?

来自主题: DotNet版 - 好像c#为了DotNet牺牲了不少
readonly
new (as a modifier)
sealed
I know they all have their usage and meanings. It looks like the designer of
C# likes to give only one meaning for a keyword other than make fewer
keywords but give them different meanings in different situations.

i think the idea is to make things very explicit to
cut down on errors and confusion. also, i think keywords
like readonly and sealed are more descriptive of
their nature and thus are more readable.

来自主题: DotNet版 - 好像c#为了DotNet牺牲了不少
I assumed that you are comparing public variable and property. Think about
the followings:
1. What if you want to make a field readonly to other classes while writable
in the in the class it's defined.
2. What if you want to do something else(logging some information for
example) before writing to the field?
3. Think about the differences in reflection, intellisense and the
generation of the library documentation

You could use dd for windows: http://www.chrysocome.net/dd.

Or you can just use PhotoRec since it's readonly so should be fairly safe.

估计主板上的电容完蛋了。电容完蛋就是这个现象。
如果想省电,弄个dockstar之类的,自己装debian或者用原生系统,大概都能达到
usb 系统的极限:26MB /s。不过要求所有的硬盘都是USB硬盘。
我用的是GoFlex Home,自己带了2TBSATA,另外配了一个500GB的USB装系统以及一些
readonly 的share,SATA的性能稍微高点,大概读写比dockstar快50%左右。SATA的
硬盘可以spin down,进一步节能以及延寿。
上述方案优点是省电,缺点是性能一般,不过播放高清之类已经可以了。如果用PC来
做,应该可以在1000M 网络上达到100MB/s或以上的速度。
如果是24小时开机,弄一堆老硬盘还不如买个新的大硬盘,能耗上不划算。1W*24h*365
大概是$1--电费如果是12c左右的话。

看上去几位都觉得中间这个参数有问题,我是拷贝的一个网上例子,原函数是:
function showhint(menucontents, obj, tipwidth){
...
dropmenuobj.x=getposOffset(obj, "left")
dropmenuobj.y=getposOffset(obj, "top")
dropmenuobj.style.left=dropmenuobj.x-clearbrowseredge(obj, "rightedge")+obj.
offsetWidth+"px"
dropmenuobj.style.top=dropmenuobj.y-clearbrowseredge(obj, "bottomedge")+"px"
dropmenuobj.style.visibility="visible"
obj.onmouseout=hidetip
}
在我的另外一个JSP(works fine)里我是这样使用showhint()的,但我的确不清楚这
儿的'this'是什么涵义,只是照猫画虎而已:

You are seeing the downstream side of stuff, which is readonly for the most
part or the loss of data is no big deal. The billing and supply chain are
heavily relying on RDBMS and moving to cloud is really difficult.

我想解决的问题是dd-wrt用ssh似乎不能显示中文,找了很久没找到解决办法,
很多系统目录都是readonly,所以想上open-wrt,这个应该都可以改吧。
这跟open-source有关吗?
flash应该不小,我装dd-wrt都是装最大的。
驱动不知道,有其他人做的一些open-wrt 的build可以用,
但据说有很多问题,就没去试。
