asp脚本中如何调用正则表达式

ASP中

VBscript示例
Function RegExpTest(patrn, strng)
Dim regEx, Match, Matches ' 建立变量。
Set regEx = New RegExp ' 建立正则表达式。
regEx.Pattern = patrn ' 设置模式。
regEx.IgnoreCase = True ' 设置是否区分字符大小写。
regEx.Global = True ' 设置全局可用性。
Set Matches = regEx.Execute(strng) ' 执行搜索。
For Each Match in Matches ' 遍历匹配集合。
RetStr = RetStr & "Match found at position "
RetStr = RetStr & Match.FirstIndex & ". Match Value is '"
RetStr = RetStr & Match.Value & "'." & vbCRLF
Next
RegExpTest = RetStr
End Function
MsgBox(RegExpTest("is.", "IS1 is2 IS3 is4"))

JScrept示例
function matchDemo(){
var s;
var re = new RegExp("d(b+)(d)","ig");
var str = "cdbBdbsbdbdz";
var arr = re.exec(str);
s = "$1 contains: " + RegExp.$1 + "\n";
s += "$2 contains: " + RegExp.$2 + "\n";
s += "$3 contains: " + RegExp.$3;
return(s);
}
