Translate REGEXP from AutoIt to JavaScript

[Iczer]

How it should be done?

Autoit regexp:

$sHeader = "attachment; filename*=UTF-8''cURL.au3"

$sFilename = StringRegExpReplace($sHeader, "(?i)(\A.*?filename)(\*?\=.*?)([^']+)$","$3")

JavaScript:

$sJavascript &= 'var responseHeaders = request.getResponseHeader("Content-Disposition");'
$sJavascript &= 'var expr = new RegExp(".*=.+?"(.+)");'
$sJavascript &= 'var fileName = responseHeaders.replace(expr,"$3");'

it working well in most cases, but if filename encoded as defined by RFC 2231, JavaScript version give wrong result and this

$sJavascript &= 'var expr = new RegExp("(\\A.*?filename)(\\*?\\=.*?)([^\\x27\\x60]+)$");'
$sJavascript &= 'var fileName = responseHeaders.replace(expr,"$3");'

also fail.

How i can correctly reproduce auto-it regexp in  JavaScript?

Could you please specify which browsers you use as the implementations have slight differences

Try this

 

var expr = /(^.*?filename)(\*?\=.*?)([^']+)$/mg;
fileName = responseHeaders.replace(expr, "$3");
