Question

ASP网站，如何提取文章页的前50字作为Description标签？

Answer 1

比如内容字段是 content

先消除 content的HTML代码 然后调用前50个字

response.write(left(stripHTML(content),50))

'消除HTMI代码
Function stripHTML(strHTML)
'Strips the HTML tags from strHTML
Dim objRegExp, strOutput
Set objRegExp = New Regexp
objRegExp.IgnoreCase = True
objRegExp.Global = True
objRegExp.Pattern = "<.+?>"
'Replace all HTML tag matches with the empty string
strOutput = objRegExp.Replace(strHTML, "")
'Replace all < and > with < and >
strOutput = Replace(strOutput, "<", "<")
strOutput = Replace(strOutput, ">", ">")
stripHTML = strOutput 'Return the value of strOutput
Set objRegExp = Nothing
End Function

Answer 2

content.substring(0,50)
或者
单独提供输入“文章摘要”的地方
