Crockford's code concerning the Constructor Invocation Pattern
function-prototypes, javascript
Solution
You're adding the method to the `Quo` function object, not to its prototype, so it will not be inherited by instances created with `new Quo()`. A function added in this way is a bit like a static method in classic OOP languages - it can be called with `Quo.get_status()`, but it won't be inherited by instances and `this` will refer to the `Quo` function itself.
Quo.status = "foo";
Quo.get_status(); // "foo"
Problem
The below code is almost identical to some code from Douglas Crockford's superb book JavaScript: The Good Parts, from pages 29-30. The only difference is that he adds the get_status property like so: ``` Quo.prototype.get_status=function() { this.status=string; } ``` My question is why his code runs OK but my little change, below, results in an error that says myQuo has no get_status method? ``` <script> var Quo=function(string) { this.status=string; } Quo.get_status=function() { return this.status; } var myQuo=new Quo("confused"); alert(myQuo.get_status()); </script> ```
