我想判斷表單獲取的procompare為空時返回上乙個頁面，不為空時之行下一句compare=trim(subid&","&trim(request.form("procompare")))，或者把procompare引數用alert彈出來！
if request.form("procompare").value="" then
response.write( "")
response.end()
else
compare=trim(subid&","&trim(request.form("procompare")))
end if
本人初學asp，可能問起有些幼稚，還望理解！請教高手，謝謝
