Include global variable into action execute javascript?

Do I have anyway to sneak in a global variable into 'browser execute javascript' action?

Some thing like, for example

var ref = cordova.InAppBrowser.open('http://===INSERT VARIABLE HERE===', '_blank', 'location=yes');

try:

Global variable c2Var = "https://www.scirra.com/"

"var myUrl ='"&c2Var&"';
var ref = cordova.InAppBrowser.open( myUrl, '_blank', 'location=yes');"[/code:2puzxi7q]

try:

Global variable c2Var = "https://www.scirra.com/"

"var myUrl ='"&c2Var&"';
var ref = cordova.InAppBrowser.open( myUrl, '_blank', 'location=yes');"[/code:1r9zr6hv]

Thank you. I'll try it out.
