具有冒号问题的__doPostback方法 [英] __doPostback method with colons problem

问题描述

我在javascript中遇到了冒号这里讨论的问题
http://www.bdragon.com/条目/ 000324.shtml 。


基本上，我有嵌套控件并在以下行中获取错误：


theform = document._ctl0：frmPage;


我注意到了一个解决方案
http://msdn.microsoft.com/msdnmag/issues/02/10/WebQA/

但是，对于每个页面来说，这似乎是一个开销！


有没有人得到任何关于是否/何时以及如何修复这些更新的更新

求助于这些修复？对我来说似乎是一个相当基本的问题，

所以希望它已经修复了，我只是缺少一些升级或

热修复!!


谢谢，

史蒂文

解决方案

FWIW：


我发现基本的问题是我在用户控件中定义了

。

然后结果是ucForm。在__doPostBack方法中被引用为

：


theform = document._ctl0：ucForm;


失败JavaScript :(


任何修复？

确定 - 我找到了1个方法（基于早期的uri）。


覆盖控件中的render方法并替换：对于控制名称

带有_。


到目前为止工作 - 有人试过这个并遇到任何问题吗？


仍然不是我想投入的东西：S $

JD JD - 我实际上已经编写了一个框架，它使用核心用户控件来实现
外观和感觉任何应用程序和所有它（可重复使用）sub

控件。我尝试了很多方法，但这是我能看到的唯一方式

它工作且仍然可以扩展。


这个主要控件托管另一个控件和页面充当一个简单的

容器，< form>包装在里面。所以控制本身永远不会在其父页面之外重复使用。


在其他情况下，我可能会编写完整的封装轮询控制。将

表单元素放入任何asp页面。我不在我的情况下，但是

我希望ASP.Net支持这种可能性！


干杯，

史蒂文。

用户控件中声明一个表单。在开发控件时，您不应该假设您的控件将被使用或不被使用。在你的情况下如果有人想在现有表格中使用你的

I am running into the "colon in javascript" problem as discussed here
http://www.bdragon.com/entries/000324.shtml.

Basically, i have nested controls and get the error on a line such as :

theform = document._ctl0:frmPage;

I noticed a solution at
http://msdn.microsoft.com/msdnmag/issues/02/10/WebQA/
However, this seems like a heck of an overhead for every page!

Has anyone got any updates on if/when and how this can be fixed without
resorting to these kind of fixes? Seems a fairly fundamental problem to me,
so hopefully it has already been fixed and i''m just missing some upgrade or
hot fix!!

thanks,
Steven

FWIW :

I have discovered that the basic problem is that i have the FORM defined
within a usercontrol.
It then turns out that "ucForm" is referenced in the __doPostBack method as
:

theform = document._ctl0:ucForm;

Fails in JavaScript :(

Any fixes?

ok - 1 way around it i have found (based on an earlier uri).

Override the render method in the control and replace ":" for control names
with "_".

Works thus far - anyone tried this and run into any probs?

Still is not something i want to put into prod :S

Hi JD - I have actually written a framework which uses a core usercontrol to
implement the look and feel any application and all it''s (reusable) sub
controls. I tried a whole host of ways, but this is the only way i can see
it working and still be extensible.

This main control hosts the other controls and the page acts as a simple
container which the <form> wrapper in it. So that control itself is never
reused outside its parent page.

In other cases i may well write a full encapsulated "poll control" with the
form element to be just dropped into any asp page. I don''t in my case, but
i''d like ASP.Net to support that possibility!

Cheers,
Steven.

The idea here is that you never declare a form within a
user control. When developing controls you should never
assume where your controls will or will not be used. In
your case what happens if someone wants to use your
control inside an existing form?
