Scaling function about react-slider HOT 9 CLOSED

I have implemented something similar to this using the existing code. I achieved it by separating the internal value and display value. I wanted to implement exponential scaling. So lets imagine I want only to have values 1, 2, 4, 8, ..., 1024. In this case I would hold in state the "internal" value (0, ..., 10) and calculate the rest on the fly:

var ExpSlider = React.createFactory(React.createClass({
    transformFromUI(value){
        return Math.pow(2, value)
    },
    transformToUI(value){
        return Math.log(value) / Math.log(2)
    },
    handleChange(value) {
        this.setState({
            value: value
        })

        this.props.handleChange(this.transformFromUI(value));
    },
    getInitialState() {
        return {
            value: this.tranformToUI(this.props.min)
        }
    },
    getDefaultProps(){
        min: 1,
        max: 1024,
        value: 1
    },
    componentWillReceiveProps(nextProps){
        this.setState({ value: this.transformToUI(nextProps.value) })
    },
    render() {
        return (
            <ReactSlider
                value={this.state.value}
                min={this.tranformToUI(this.props.min)}
                max={this.tranformToUI(this.props.max)}
                onChange={this.handleChange}
            >
                <div>{this.tranformToUI(this.state.value)}</div>
            </ReactSlider>
        );
    }
}))

With this approach you can create slider with 100 values between 0.0 and 1.0 just by dividing and multiplying by 100 and using Math.floor or similar scaling and step you want.

Please excuse any issues as I did not have time to to create an example. But something similar works quite well in my code.

I agree with @lukashlavacka's solution. A scaling function doesn't really need to be present in this plugin since you can just calculate that elsewhere.

has any of you come up with a solution since june @dmitry @raulmatei ?

@alexmugford how does this related to the #40?

@dmitry sorry, misunderstood the scaling being requested!

Is this something that the authors would be willing to accept a PR for? I'd happily implement the scaling function if it's something the authors would like to have in their project.
