| + | |||
| + | Private methods are possible as inline constructor functions: | ||
| + | |||
| + | <code javascript> | ||
| + | function MyClass() { // The constructor | ||
| + | var privateVariable= 10; // A private instance variable | ||
| + | var privMeth1= function {...} // A private method | ||
| + | fuction privMeth2 {...} // private method (shortcut) | ||
| + | var that= this; // To make this available for priv methods | ||
| + | } | ||
| + | </code> | ||
| + | |||
| + | Notes: | ||
| + | * Private methods possibly cause overhead, compared to the prototype way of public methods | ||
| + | * ''this'' seems only to be accessible in private methods by the ''that'' workaround variable above | ||
| + | * Public methods defined with the (recommended) ''prototype''-way doesn't seem to have access to private mehtods. You need privileged methods (see above) for that. | ||
