我在移动菜单中向上和向下滚动无法正常工作。我将在下面显示源代码:
className = { classNames( { icon: true, scrollActive: this.state.vPos > 0,
mobileNavActive: this.state.mobileToggle })}
onClick={this.toggleMobileNav.bind(this)}>
className={classNames({ nav_wrap: true, scrollActive: this.state.vPos > 0,
mobile_active: this.state.mobileToggle })}>
怎么了?
