将字符串从客户端移动到服务器（JS - > ASPX） [英] Moving a string from client to server (JS -> ASPX)
问题描述
在client.js文件中，我声明
跟随变量。
...
var str =" ; info" ;;
...
在相应的ASP文件中，名为
server.aspx.cs我声明了两个以下
方法。
...
protected void Page_Load（
对象发送者，EventArgs e ）{...}
public void SomeThing（）{
...
字符串数据;
......}
...
目标是_SOMEHOW_确保
表示数据的价值（在CS中）文件）
是从str获得的（在JS文件中）。
请注意，我不需要数据
$ b一旦str改为
，$ b就会动态更新。每次我们传递
部分代码时，只需调用
" info"
" info" ;到str。
另请注意我需要通知
SomeThing关于str的值。
Of当然，实际情况很远
更复杂但我的问题可以是
归结为这个简单的案例。
如何应该设计SomeThing吗？怎么
需要我重建行后
赋值给str？

In the client.js file i declare the
following variable.
...
var str = "info";
...
In the corresponding ASP file called
server.aspx.cs i declare two following
methods.
...
protected void Page_Load (
object sender, EventArgs e){...}
public void SomeThing () {
...
String data;
...}
...
The objective is to _SOMEHOW_ ensure
that the value of data (in the CS file)
is obtained from str (in the JS file).
Note that i don''t need data to be
dynamically updated as soon as str is
changed. It''s sufficient to call the
method SomeThing each time we pass the
part of code where we assign the value
"info" to str.
Note also that i need to notify
SomeThing about the value of str.
Of course, the actual situation is far
more complicated but my problem can be
boiled down to this simple case.
How should SomeThing be designed? How
need i to reconstruct the lines after
the assignment to str?

如果没有其他HTTP请求（可以是XHR）就无法完成，因为两个

您的帖子不容易辨认。代词我总是拼写为
大写字母，你的行长约为预期的一半
使用网络中的
（建议每行80个字符）最大值，72到78到
允许报价而无需重新格式化）。此外，在顶级
层次结构上交叉发布是不明智的，因为新闻服务器可能在Big 8中有comp。*
（Usenet）但不包括microsoft。*不属于那个。所以
的讨论会变得支离破碎，TLH中的沟通惯例
也可能不同。

Prototype.js是由不懂javascript的人写的适合人们
谁不懂javascript。不知道javascript的人不是设计使用javascript的系统的最佳建议来源。

It cannot be done without another HTTP request (can be XHR) because the two
don''t know about each other. If you don''t know that by now, you should get
some basic knowledge about client-server architectures first, before messing
around with them.
Your posting was not easily legible. The pronoun `I'' is spelled with a
capital letter always and your line length is about half of what is expected
in Usenet (80 characters per line is the recommended maximum, 72 to 78 to
allow for quotation without reformat). Also, cross-posting over top-level
hierarchies is unwise as a news server may have comp.* within the Big 8
(Usenet) but not microsoft.* which does not belong to that. So the
discussion is going to be fragmented, and the conventions of communication
in the TLHs may also differ.

谢谢！试着不要不礼貌我仍然需要指出问题
是怎么做，而不是相反。您是否建议
是从
服务器请求（另一个）页面的唯一（推荐）方式？当然，这在我的情况下是可行的，但我不想使用 file.aspx？str = infotarget =_ blank> http：//.../file.aspx？str = info 。
也许我可以烘烤它在发件人对象中。你觉得怎么样？

Thanks! Trying not to be impolite i still need to point that the question
was "how can it be done", not the opposite. Are you suggesting that
the only (recommended) way to to request (another) page from the
server? It would be doable in my case, of course, but i''d prefer not to
send in the string using http://.../file.aspx?str=info.
Perhaps i could bake it in the sender object. What do you think?

欢迎使用HTTP ;-)这是一个无状态协议，因此在页面为客户端提供
后，有_no_连接
页面与服务器之间的任何类型：无。
HTTP之后的唯一通信方式是新请求
已启动由客户端：服务器无法发起任何事情。
Welcome to HTTP ;-) It is a stateless protocol, so after the page is
served to the client, there is _no_ connection of any kind between the
page and the server: none.
The only way of communication HTTP has after that is a new request
initiated by the client: the server has no way to initiate anything.
当然，在我的情况下这是可行的，但我不想
使用 http：// ...发送字符串/file.aspx?str=info 。
你不必这样做。使用AJAX或ol''ood隐藏的iframe
连接到服务器并报告新的src值。
You don''t have to do that. Use AJAX or ol''good hidden iframe to
connect to the server and to report new src values.
