REGEXP
函数可以匹配标准的URL格式。如果需要提取URL,可以使用SUBSTRING_INDEX()
和LOCATE()
等字符串函数。REGEXP
函数可以匹配标准的URL格式。如果需要提取URL,可以使用SUBSTRING_INDEX()
和LOCATE()
等字符串函数。asp,Function CheckLink(url), Dim httpRequest, Set httpRequest = Server.CreateObject("MSXML2.ServerXMLHTTP"), httpRequest.Open "GET", url, False, On Error Resume Next, httpRequest.Send, If Err.Number 0 Then, CheckLink = False, ElseIf httpRequest.Status = 200 Then, CheckLink = True, Else, CheckLink = False, End If, On Error GoTo 0, Set httpRequest = Nothing,End Function,
`,,这个函数使用
MSXML2.ServerXMLHTTP`对象发送HTTP请求到指定的URL,并根据响应状态码来判断链接是否正常。如果状态码是200,则表示链接正常;否则,表示链接不正常。asp,Function IsValidEmail(email), Dim regEx, Match, Set regEx = New RegExp, regEx.Pattern = "^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$", regEx.IgnoreCase = True, regEx.Global = True, Set Match = regEx.Execute(email), If Match.Count > 0 Then, IsValidEmail = True, Else, IsValidEmail = False, End If,End Function,
``,,这个函数使用正则表达式来验证输入的邮箱地址是否符合标准格式。asp,,
``asp,Function RemoveNonNumeric(str), Dim regEx, Set regEx = New RegExp, regEx.Pattern = "\D", regEx.Global = True, RemoveNonNumeric = regEx.Replace(str, ""),End Function,
``,,这个函数会将输入字符串中的所有非数字字符替换为空。Replace()
函数逐个替换常见的HTML标签。,2. 使用正则表达式和RegExp
对象来匹配并删除所有HTML标签。,3. 利用第三方组件或库,如Microsoft HTML Object Library
,来解析和清除HTML内容。asp,Dim str, arr,str = "apple,banana,cherry",arr = Split(str, ","),
`,,这段代码会将字符串
str按照逗号
,进行分割,并将结果存储在数组
arr`中。Powered By Z-BlogPHP 1.7.3
