新闻if-then-else问题 [英] newsbie if-then-else question
问题描述
你好，
我刚刚转向ASP。我过去两年一直在用PHP开发
年。我必须说，我对
初学者教程的质量有点失望。他们没有进一步教学
<％Response.Write（Hello World）％>
我还缺少一个官方网站，所有ASP命令都解释过，比如
你有php.net for PHP。
无论如何，我走了，这段代码包含一个错误：
If（lang2 =" DUT" OR lang2 =" dut" OR lang2 =" NL" OR lang2 =" nl"）
然后（
left =" column_left_nl.html"
top =" top_nl.html"
）
否则if（lang2 =" FRE" OR lang2 =" fre" OR lang2 =" FR" OR
lang2 =" fr"）然后（
left =" column_left_fr.html"
top =" top_fr.html"
）
否则if（lang2 = " ENG"或lang2 =" eng"）然后（
left =" column_left_eng.html"
top =" top_eng.html"
）
结束如果
没有教程可以解释我是否使用括号
以及我应该使用哪种括号。那么，我需要所有这些
括号吗？
为什么：
lang =" DUT" ;
a声明，还有几行比较？
我真的很困惑，请帮帮我。
格雷茨，
巴顿
你可能会更快乐...更开心，用C＃。这是一个更加特殊/硬性的语言，没有那么多的假设，比如
VB。使用ASP.NET，您可以使用任何符合CLR的语言编写应用程序
（VB.NET，C＃，J＃，托管C ++？）..这里是C＃中的代码：
if（lang2 ==" DUT" || lang2 ==" dut" || lang2 ==" NL" || lang2 ==" nl"）
{
left =" column_left_nl.html";
top =" top_nl.html";
}
elseif（lang2 ==" FRE" || lang2 ==" fre" || lang2 ==" FR" || lang2 ==" fr"）
{
left =" column_left_fr.html";
top =" top_fr.html";
}
elseif（lang2 ==" ENG"
|| lang2 ==" eng"）
{
left = " column_left_eng.html";
top =" top_eng.html";
}
没有假设。 =用于分配，==用于比较..
分号终止一条线等等......

Hello,
I just made to move to ASP. I have been developing in PHP the past two
years. I must say that I''m a little disappointed in the quality of the
beginners tutorials. They don''t go further then teaching
<% Response.Write("Hello World") %>
I also lack an official website with all ASP commands explained, like
you have php.net for PHP.
Anyway, here I go, this piece of code contains a bug:
If (lang2 = "DUT" OR lang2 = "dut" OR lang2 = "NL" OR lang2 = "nl")
Then (
left = "column_left_nl.html"
top = "top_nl.html"
)
Else if (lang2 = "FRE" OR lang2 = "fre" OR lang2 = "FR" OR
lang2 = "fr") Then (
left = "column_left_fr.html"
top = "top_fr.html"
)
Else if (lang2 = "ENG" OR lang2 = "eng") Then (
left = "column_left_eng.html"
top = "top_eng.html"
)
End If
There is no tutorial that explains me whether to use brackets or not
and which kind of brackets I should use. So, do I need all these
brackets?
And why is:
lang = "DUT"
a declaration, and a couple lines further a comparison?
I''m really confused, please help me out.
Greetz,
Barton
You might be happier... much happier, with C#. It''s a much more
specific/hard-lined language where there aren''t as many assumptions, like in
VB. With ASP.NET, you can write your app in any CLR-compliant language
(VB.NET, C#, J#,managed C++?).. here''s that code in C#:
if (lang2 == "DUT" || lang2 == "dut" || lang2 == "NL" || lang2 == "nl")
{
left = "column_left_nl.html";
top = "top_nl.html";
}
elseif (lang2 == "FRE" || lang2 == "fre" || lang2 == "FR" || lang2 == "fr")
{
left = "column_left_fr.html";
top = "top_fr.html";
}
elseif (lang2 == "ENG"
|| lang2 == "eng")
{
left = "column_left_eng.html";
top = "top_eng.html";
}
There are no assumptions. = is for assignment, == is for comparison..
semi-colons terminate a line, etc, etc...
