那是不是.Net Framework的错误。

完全相同的事情发生在没有.Net Framework的Javascript中。


scriptString构建一个JavaScript客户端函数。分离结束标记可以防止Javascript被动态解释：

scriptString + ="< / script&quot ;;
scriptString + =">&quot ;;


如果在呈现页面时执行JavaScript，

而不是点击按钮时，你会遇到更糟糕的问题。 />

嗨Juan，


非常感谢你回答我的问题。


我对此进行了进一步检查。我发现了一些东西。


1.重申一下：当脚本的声明分开时

"< / script"和>在Test.aspx中：

- 文件在Web Matrix的设计视图中显示正常;

- 在Web Matrix的关联Web服务器中正常运行;最终

- 在Firefox中显示一个表单正常工作。


2.但是，如果我双击Test.aspx，Visual Web Developer会来

up和barfs立刻。除其他外，它标记行：

scriptString + ="< / script&quot ;;

投诉：

无法切换views：验证（Internet Explorer 6）：字符

''"''在结束标记内无效。


3.努力了解你的评估完全相同的事情

发生在没有.Net Framework参与的Javascript中，我的b $ b组成了下面显示的HTML文件，在Firefox和IE中运行良好

（关闭脚本标签正常写入。）


如果你有时间，可以进一步了解我的经历和

进一步评估。


再次，感谢您花时间考虑我的困惑。


您真的，

Hi All,

The ASPX file below runs fine in ASP .NET WebMatrix 0.6 under WinXP/SP2
with IIS 5.1 and .NET Framework 1.0, 1.1 and 2.0.

But if the last scriptString line is eliminated after appending the
closing ">" to the preceding line, the compiler flags that last line in
the browser (Firefox 5.0) with the message:

Compiler Error Message: CS1010: Newline in constant

The same line is flagged immediately in Visual Web Developer 2005 Expr.
Ed., version 8.0.50727.42, with "Newline in constant". VWD also
complains that the final </script> had no matching start tag.

Is this a "universal bug" :-), or are both caused by a bug in the .NET
C# compiler?

An ideas? Is this too trivial to worry about?

TIA,
Richard

That is not a .Net Framework bug.
The exact same thing happens in Javascript without the .Net Framework being involved.

scriptString builds a JavaScript client function.

Separating the closing tag prevents the Javascript from being interpreted on the fly:

scriptString += "</script";
scriptString += ">";
If the JavaScript executed when the page is rendered,
instead of when the button''s clicked, you''d have worse problems.

Hi Juan,

Thank you very much for responding to my question.

I checked further on this. I''ve discovered a few things.

1. Just to reiterate: When the declartion of of the script separates
"</script" and ">" in Test.aspx:
-- the file displays fine in Web Matrix''s Design view;
-- runs fine in Web Matrix''s associated Web Server; and ultimately
-- displays a form in Firefox which works fine.

2. However, if I double-click Test.aspx, Visual Web Developer comes
up and barfs immediately. Among other things, it flags the line:
scriptString += "</script";
with the complaint:
Cannot switch views: Validation (Internet Explorer 6): Character
''"'' is not valid inside closing tags.

3. In an effort to understand your assessment "The exact same thing
happens in Javascript without the .Net Framework being involved", I
composed the HTML file shown below which runs fine in Firefox and IE
(with the closing script tag written normally.)

If you have time, could you take a further look at my experiences and
assess it further.

Again, thanks for taking the time to consider my confusion.

Yours truly,
Richard

You need to understand the difference between writing a Javascript block in a file
which will only be rendered and displayed, and writing a Javascript block in a file,
like in ASP and ASP.NET, which needs to be interpreted, compiled and displayed.
