条件response.write的问题 [英] problem with conditional response.write

问题描述

您好


当我检查数据库中是否有值时，我需要能够在屏幕上打印


< td> ;

<％if（（Recordset1.Fields.Item（" profile1"）。Value）<>

""）then response.Write" ; Pro1的<峰; br>" &

Recordset1.Fields.Item（" profile1"）。Value％>


< / td>

我正在检查profile1是否包含任何文本，如果不打印任何内容。如果

是，那么打印标题和内容。

现在问题是我似乎无法检查值并打印相同的

价值。

如果我检查profile2而不是profile1（包含一个值）那么打印

profile1。

目前只有Pro1是写入屏幕但是

profile1的内容不是，尽管profile1不是空的。


可能出错了什么？


谢谢

Hi there

I need to be able to print on screen when I check if a value within a db

<td>
<% if ((Recordset1.Fields.Item("profile1").Value) <>
"") then response.Write"Pro1<br>" &
Recordset1.Fields.Item("profile1").Value%>

</td>

I am checking if profile1 contains any text if not don''t print anything. If
yes then print the heading and the contents .
Now the problem is that I cannot seem to check the value and print the same
value.
If I check profile2 instead of profile1 (which contains a value) then
profile1 is printed.
At the moment only Pro1 is written to the screen but the contents of
profile1 is not, eventhough profile1 is not empty.

What could be wrong ??

Thanks

推荐答案

现在我将从写作开始：

Response.Write Recordset1.Fields .Item（" Profile1"）。value =""

以确保这不是一个空字符串。


如果不是，它可能是null或包含空格的字符串（特别是如果DB字段使用CHAR而不是VARCHAR，则为
）...

For now I would start by writing :
Response.Write Recordset1.Fields.Item("Profile1").value=""
to make sure this is not an empty string.

If not it could be null or a string that contains white spaces (especially
if the DB field uses CHAR instead of VARCHAR)...

Hi there are no emty strings..
Also the text ''Pro1'' is written to screen meaning that part of it executes
but not the Recordset1.Fields.Item("profile1").Value bit in its current
surroundings..

不确定这是不是回应我的建议。


我的意思是如果profile1持有 "它将打印Pro1（因为这

不是"），但你看不到任何可见的东西。同样地，如果值为

null并且如果我记得我的ASP日期很好，它将打印Pro1（因为这不是

""）但是你赢了''什么都看不到。


我真的会仔细检查。如果仍然无法打印这些值并向我们报告

：

Value<>"" ''它肯定会允许找出值

是否为空字符串

IsNull（Value）''它将允许查找是否为NULL

Len（Value）''它可以查找是否包含不可见的

字符

Not sure if this is a response to my suggestion.

What I meant is that if profile1 holds " " it will print Pro1 (as this
is not "") but you won''t see anything visible. Similarly if the value is
null and if I remember well my ASP days, it will print Pro1 (as this is not
"") but you won''t see anything either.

I would really double check. If it still fails print those values and report
them to us :
Value<>"" '' It would definitely allows to find out if the value
is an empty string or not
IsNull(Value) '' It would allow to find is this is NULL
Len(Value) '' It would allow to find if it contains non visible
characters
