1 Object.defineProperty(global, '__stack', { 2   get: function(){ 3     var orig = Error.prepareStackTrace; 4     Error.prepareStackTrace = function(_, stack){ return stack; }; 5     var err = new Error; 6     Error.captureStackTrace(err, arguments.callee); 7     var stack = err.stack; 8     Error.prepareStackTrace = orig; 9     return stack;10   }11 });12 13 Object.defineProperty(global, '__line', {14   get: function(){15     return __stack[1].getLineNumber();16   }17 });18 19 console.log(__line);

上面的代码应该输出 19

 

另外

__dirname　　当前路径   /Users/dev08/test

__filename　　当前文件名  /Users/dev08/test/sc.js
