sammyjs optional parameters

Question

Just wondering if there is anyway to specify a parameter as optional in a sammy js route.

I\'ve seen somewhere that you can use

route/:foo/?:bar

Sammy actually dropped the ball when it comes to optional parameters and querystrings. The only way I could get this to work fairly well is to use regular expressions and the splat object. In your example, you would write :

this.get(/\#\/route\/(.*)\/(.*)/, function (context) {
        var result = this.params['splat'];
});

The downside is that you need the backslash at the end of the URL when the optional parameter is omitted.

The splat object is the actual result of the JavaScript match method and is an array.

'#/route/test/' => {result[0]: 'test', result[1]: ''}
'#/route/test/chicken' => {result[0]: 'test', result[1]: 'chicken'}
