复现步骤

<ScrollView onScroll={this.onScroll.bind(this)}>
xxx
</ScrollView>
onScroll(evt, event){
    console.log(evt) // 打印出来是 "this" 字符串
    console.log(event) // 打印出来是滚动事件
}

其他尝试

  1. 将方法名改为 onListScroll等都会复现
  2. 但将方法名改为 onPageScroll,可正常执行,但onPageScroll是小程序滚动页面的事件
  3. 如果在bind后面增加参数,如this.onScroll.bind(this, 'xxx')。打印:第一个参数是"xxx",第二个参数是 "this",第三个参数是 event

期望行为
evt即为滚动事件,而非第二个参数

@figo-fe 事件对象排在所有参数最后是正常现象。

@Chen-jj 我也遇到了...

44001547173697_ pic
44041547173736_ pic_hd
44031547173720_ pic

绑不绑定this , 输出都是第一个为字符串的this,第二个才是event details

不合理...不用...来聚合args的话,拿到的是this字符串

@crper 这是因为cli和依赖包版本不一致导致,开发前必须确保他们版本一致
