                # Scrubbing.js

Highly customizable mouse scrubbing implementation for numbers and custom data.

[More info on GitHub](https://github.com/FWeinb/Scrubbing.js)


## Horizontal 

This is the default behaviour

    new Scrubbing ( document.querySelector ( '#scrubbing-horizontal') );

<p class="center">
  <span class="big" id="scrubbing-horizontal">20</span>
</p>

## Horizontal / with mouse wheel

It is possible to add more than on driver. 

    new Scrubbing ( document.querySelector ( '#scrubbing-horizontal-wheel')
                  , { driver : [ Scrubbing.driver.Mouse,
                                 Scrubbing.driver.MouseWheel,
                                 Scrubbing.driver.Touch
                               ]});

<p class="center">
  <span class="big" id="scrubbing-horizontal-wheel">20</span>
</p>

## Vertical 

You change the scrubbing to vertical by using the passing `'DefaultVertical'` 

    new Scrubbing ( document.querySelector ( '#scrubbing-vertical' )
                  , { resolver : 'DefaultVertical' } );

or using `Scrubbing.resolver.DefaultVertical` 
    
    new Scrubbing ( document.querySelector ( '#scrubbing-vertical' )
                  , { resolver : Scrubbing.resolver.DefaultVertical } );


<p class="center">
  <span class="big" id="scrubbing-vertical">20</span>
</p>


## Vertical / with friction 

By using a the `Scrubbing.resolver.VerticalProvider ( friction )` you can change the `friction` of the Scrubber.

    new Scrubbing ( document.querySelector ( '#scrubbing-vertical-friction' )
                  , { resolver : Scrubbing.resolver.VerticalProvider ( 50 ) } )
                 
<p class="center">
  <span class="big" id="scrubbing-vertical-friction">20</span>
</p>

## Horizontal / with custom Values

By implementing your own `adapter` you can output custome values. 
Here it is a Excel like letter iterator. 

    new Scrubbing ( document.querySelector ( '#scrubbing-horizontal-custom')
                  , { adapter  : MyOwnAdapter 
                    , resolver : Scrubber.resolver.HorizontalProvider ( 30 ) });

<p class="center">
  <span class="big" id="scrubbing-horizontal-custom">B</span>
</p>


## Horizontal / width array values

Another `adapter` could be an ArrayAdapter that would scrub though array values.

    new Scrubbing ( document.querySelector ( '#scrubbing-horizontal-array')
                  , { adapter  : new ArrayAdapter(["Test",  "Test1", "Test2"
                                                  ,"Test3", "Test4", "Test5"
                                                  ,"Test6"])
                    , resolver : Scrubbing.resolver.HorizontalProvider ( 50 )})

<p class="center">
  <span class="big" id="scrubbing-horizontal-array">A</span>
</p>
