Running Jscript demo functions from MSDN samples.

I’ve tried to port Query Parser written in JScript from Integrating User Search with ASP and Microsoft SQL Server Full-text Search to C#. The “Converting JScript.NET to C#” tool is quite useful, but doesn’t do all the job. I wanted to understand  RegExp properties , but MSDN JScript  help example doesn’t show output. So I’ve wrote simple exampleRun.js using WScript.Echo:


WScript.Echo (matchDemo());


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 + “n”;


   s += “input returns : ” + RegExp.input + “n”;


   s += “lastMatch returns: ” + RegExp.lastMatch + “n”;


   s += “leftContext returns: ” + RegExp.leftContext + “n”;


   s += “rightContext returns: ” + RegExp.rightContext + “n”;


   s += “lastParen returns: ” + RegExp.lastParen + “n”;


   return(s);


}


Which produces the following output
$1 contains: bB


$2 contains: d


$3 contains:


input returns : cdbBdbsbdbdz


lastMatch returns: dbBd


leftContext returns: c


rightContext returns: bsbdbdz


lastParen returns: d

Update: I’ve noticed,that MSDN Jscript.NET  help includes the output, which is quite nice.
