again for variable from js to xslt

the variable to be transfered(bSwitch) is a globle variable in a1.js.
and the input xml file is in a function(getfile(sXMLinput)) in a2.js.
how to put these sentences:

var source = new ActiveXObject("MSXML2.DOMDocument.3.0");
source.async = false;
source.load("http://localhost/Display.xsl");
var XSLTemplate = new ActiveXObject("MSXML2.XSLTemplate.3.0");
XSLTemplate.stylesheet = source.documentElement
var myProc = XSLTemplate.createProcessor();
myProc.input = sXMLinput;
myProc.addParameter("Switch",bSwitch,"");
myProc.transform;

Thank you very much!
