Accessing local variables defined in outer function inside callback

[Ram Mulage]

Hi All,

Sorry, I posted my previous question bit prematurely and I will delete it after I find it.  I am asking that question again,  can we access variables defined inside outer function inside the callback?

router.get('/', function(req, res)

{

utils.dump("viewer::get - " + __filename);

dbutils.fetchMasterConfig(function(config)

{

                var ip = req.ip;

                someClass.someFunc(par1, par2, function(err, file)

                {

                     console.log("ip = " + ip); // is ip accessbile at this scope?

                   

                )};

         });

});

TIA

Hi Ram,

It is accessible because the callback function has been defined in the context of callback of router.get().

Perfectly valid. The callback will have its own context, however this does not effect the scope.

Thank you all. I was using very old NodeJS (0.15 I think) and looks like it is some kind of bug in nodejs. I fixed it using a global variable but I guess the latest NodJS may have fixed this issue/
