js的hover实现方法。

onMouseEnter={(utils.isiPad() || utils.isPhone()) ? () => { } : () => this.toggleHoverEnter(modules.length, index)}

onMouseLeave={(utils.isiPad() || utils.isPhone()) ? () => { } : () => this.toggleHoverLeave(modules.length, index)}

 

toggleHoverEnter = (length, index) => {

let _num = new Array(length + 1).join(0).split('');

    _num[index] = 1;

    this.setState({

        num: _num

     })

}

toggleHoverLeave = (length, index) => {

let _num = new Array(length + 1).join(0).split('');

    _num[index] = 0;

    this.setState({

        num: _num

     })
