javascript - Get all variables of the current function() scope -

i'm having problem. want current function scrope. have example code i'm working ok.

function nittle(){      var pen = new dot(); // generated dynamical through eval()     .....      for(key in window) {         if( window[key] instanceof dot ){             alert("found it");         }     }  } 

but seems not work within function scope. work outside of it. there work around ?

thanks.

i'm not aware of way determine programmatically variables have been declared inside function, except perhaps use nittle.tostring() , attempting parse find variables. maybe work you? (but it's messy me attempt here.) update: if variables created via eval() won't work, you'd see eval() statement in function's string representation.

is there work around ?

you declare single object in function , change variables properties of object:

function nittle() {   var nittlevars = {      var1 : "something",      pen : new dot(),      etc : "whatever"   };    (var key in nittlevars){     if( nittlevars[key] instanceof dot ){         alert("found it");     }   } } 

your update indicates variables created eval() - still object properties idea:

  eval("nittlevars.newvar = new dot()");  // inside function
