问题描述
往子组件传参,类型为函数,子组件调用 this.props.onXXX 无效。
复现步骤
[复现问题的步骤]
父组件:
handleAreaClick = () => { console.log('22222222222') } render() { return ( <View className='page page-index'> <Dropdown title={this.getAreaName()} onClick={this.handleAreaClick} /> </View> ) }

子组件:
` handleClick = () => {
const { onClick } = this.props
if (onClick) {
console.log('111')
onClick()
}
}

render() {
const { customStyle, className, title, open } = this.props

return (
  <View
    className={classNames('yt-dropdown', className)}
    style={customStyle}
    onClick={this.handleClick.bind(this)}
  >
  </View>
)

}`

子组件调用 this.props.onClick(),无效

期望行为

子组件能成功触发父组件传参进来的函数

@lansepan 如何解决呢?我发现taro似乎不支持子组件通过props调用父组件内的setState方法来更新?
