## Description of data passed to callbacks (onChange and etc.)
Result is object type and passed to callback as first argument:
```javascript
Obj: {
    "input": object,            // jQuery-link to input
    "slider": object,           // jQuery-link to sliders container
    "min": 1000,                // MIN value
    "max": 100000,              // MAX values
    "from": 10000,              // FROM value
    "from_percent": 10,         // FROM value in percents
    "from_value": 0,            // FROM index in values array (if used)
    "to": 90000,                // TO value
    "to_percent": 90,           // TO value in percents
    "to_value": 0,              // TO index in values array (if used)
    "min_pretty": "1 000",      // MIN prettified (if used)
    "max_pretty": "100 000",    // MAX prettified (if used)
    "from_pretty": "10 000",    // FROM prettified (if used)
    "to_pretty": "90 000"       // TO prettified (if used)
}
```

## Creating slider (all params)
An example of a customised slider:
```javascript
$("#example").ionRangeSlider({
    skin: "big",
    min: 0,
    max: 10000,
    from: 1000,
    to: 9000,
    type: 'double',
    prefix: "$",
    grid: true,
    grid_num: 10
});
```

You can also initialise slider with <code>data-*</code> attributes of input tag:
```html
data-min="0"
data-max="10000"
data-from="1000"
data-to="9000"
data-type="double"
data-prefix="$"
data-grid="true"
data-grid-num="10"
```

## Public methods

To use public methods, at first you must save slider instance to variable:
```javascript
// Launch plugin
$("#range").ionRangeSlider({
    type: "double",
    min: 0,
    max: 1000,
    from: 200,
    to: 500,
    grid: true
});

// Saving it's instance to var
var slider = $("#range").data("ionRangeSlider");

// Fire public method
slider.reset();
```

There are 3 public methods:
```javascript
// UPDATE - updates slider to any new values
slider.update({
    from: 300,
    to: 400
});

// RESET - reset slider to it's first values
slider.reset();

// DESTROY - destroys slider and restores original input field
slider.destroy();
```
