変数を表示したいときは "<%=con("notes")%>" を使用しますが、if ステートメントでそれを使用するにはどうすればよいですか? 例えば:

<% if con("notes") = "" then
  response.write("")
  else
  response.write("<tr><td colspan='8'><strong>Notes:</strong> ") 
  response.write(con("notes"))
  response.write("</td></tr>")
  end if
  %>

うまくいかないようです。エラーは発生しませんが、多くのメモが空であることはわかっているため、コードで response.write("") を頻繁に使用する必要があります。

誰でもアイデアはありますか?

以下のコード全体:

<%@CODEPAGE=65001%> 
<%
pagetitle="Aircraft and Simulator Multi-use List 06/074"
%>
<!--#INCLUDE VIRTUAL="/_lib/include/header.htm"-->
<!--#INCLUDE VIRTUAL="/_lib/include/menu.htm"-->
<script>
$(document).ready(function() {
    $("#state").change(function () {
    this.form.submit();
})
$('#supplier_name, #aircraft_type').focus()
$("#supplier_name").val($("#supplier_name").val());
$("#aircraft_type").val($("#aircraft_type").val());
var typingTimer;                
var doneTypingInterval = 800;  

$('#supplier_name, #aircraft_type').keyup(function(){
    clearTimeout(typingTimer);
    if ($('#supplier_name, #aircraft_type').val) {
        typingTimer = setTimeout(doneTyping, doneTypingInterval);
    }
});

function doneTyping () {
    $("form").submit();
}

});

「Notes:」を含むテーブル行を大量に受け取っていますか? データベースからデータを読み取るときに、TRIM「」と等しいかどうかを確認するときに結果が必要になることがあります。

if Trim(con("notes") & "") = ""

または、データベースのメモ フィールドに改行などの他の文字が格納されている可能性があります。ソースを表示して、何が印刷されているかを確認できるはずです。

お役に立てれば。

幸運を。

sgeddesの回答でうまくいかない場合はわかりませんが、MicrosoftTextDriverがnullを返す可能性があると思います。nullもチェックできます(これはClassic ASPの「IsNull(arg)」関数だと思います)。
