ASP 检测字符串是否包括汉字、数字、韩文、日文,以及其他语种字符的方法
网页要用utf-8编码方式,用GB2312编码无法检测。

文件内容如下,请存为Test.asp
<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%> <%Session.CodePage=65001%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>测试字符属性</title> </head> <body> <%Response.Charset = "utf-8"%> <%Dim HasHZ, HasEn, HasNum, KeyWord KeyWord = Request("KeyWord") If KeyWord<>"" Then HasHZ = 0 HasEn = 0 HasNum = 0 HasJP = 0 HasKR = 0 ‘判断汉字 If RegExpTest("[\u4e00-\u9fa5]", KeyWord) Then HasHZ = 1 End If ‘判断英文 If RegExpTest("[a-zA-Z]", KeyWord) Then HasEn = 1 End If ‘判断数字 If RegExpTest("[0-9]", KeyWord) Then HasNum = 1 End If ‘判断日语 If RegExpTest("[\u0800-\u4e00]", KeyWord) Then HasJP = 1 End If ‘判断韩语 If RegExpTest("[\u3130-\u318F]", KeyWord) Then HasKR = 1 ElseIf RegExpTest("[\uAC00-\uD7A3]", KeyWord) Then HasKR = 2 End If Response.write "<BR>关键词:" & KeyWord & "<BR>汉字 = " & HasHZ & "<BR>英文 = " & HasEn & "<BR>数字 = " & HasNum & "<BR>日文 = " & HasJP & "<BR>韩文 = " & HasKR End If Function RegExpTest(patrn, strng) Dim regEx, retVal ‘ 建立变量。 Set regEx = New RegExp ‘ 建立正则表达式。 regEx.Pattern = patrn ‘ 设置模式。 regEx.IgnoreCase = False ‘ 设置是否区分大小写。 retVal = regEx.Test(strng) ‘ 执行搜索测试。 If retVal Then RegExpTest = True Else RegExpTest = False End If End Function%> <form method="POST" action="Test.asp"> <p><input type="text" name="KeyWord" size="20" value="<%=KeyWord%>"><input type="submit" value="提交" name="B1"><input type="reset" value="重置" name="B2"></p> </form> </body> </html>
附上:Unicode编码布局如下,如需判断其它编码字符,只需将正则表达式中的编码范围替换为以下对应的编码范围及可。
Unicode 到目前为止所定义的五个平面中,第0平面(BMP)最为重要,其编码分布如下:
