剛才又有人問到用JavaScript來驗證日期,回想起自己寫了一堆函數(shù)來驗證日期,而且還沒有涉及到閏年的問題,近來看 到ASP 3.0關于On Error Resume Next的用法,靈機一動,嘿嘿……。真爽呀! <% Option Explicit Dim strDate '記錄輸入的日期,字符型 Dim datDate '測試輸入的日期是否正確,日期型<html> %> <head> <title>日期選擇</title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <link rel="stylesheet" href="../Css/export.css" type="text/css"> </head>
<body bgcolor="#FFFFFF" text="#000000">
<Form name="InputDate" ACTION="<% = Request.ServerVariables("SCRIPT_NAME") %>" METHOD="POST"> <table width="500" border="1" cellpadding="0" cellspacing="0" align="center"> <tr> <td background="../Pic/br.jpg"> <table width="500" border="0" cellpadding="4" cellspacing="4" class="9p"> <tr> <td colspan="2"> </td> </tr> <tr> <td colspan="2" height="60"> <div align="center">請輸入所要查詢的日期: <input type="text" name="strDate" value="<% = Cstr(Year(Now())) & "-" & Cstr(Month(Now())) & "-" & Cstr(Day(Now()))%>" size="10" maxlength="10"> </div> </td> </tr> <tr> <td width="50%"> <div align="center"> <input type="submit" name="Submit" value="確 認"> </div> </td> <td> <div align="center"> <input type="reset" name="Submit2" value="取 消"> </div> </td> </tr> </td> </tr>
</Form> <% strDate = Request.Form("strDate") If strDate <> "" Then On Error Resume Next datDate = CDate(strDate) If Err.Number = 0 Then %> <Script Language="JavaScript"> <!-- InputDate.action="TypeAlert.asp" InputDate.submit() //--> </Script> <% Else %> <Script Language="JavaScript"> <!-- alert ("你輸入的日期不正確,請重新輸入!") //--> </Script> <% End If End If %> </body> </html>
