试一下呗
我对react研究不深
按道理instance也是有onchange的
回复好快,大佬不用上班吗

大佬这种情况怎么处理,一个输入框,没有监听器
尝试了这个,
这样试试：
const prop = Object.keys(ele).find(p => p.startsWith('__reactInternalInstance'));
ele.pendingProps.onChange(evt);

这样试试：
{:4_93:}感谢大佬,pendingProps里面没有onChange这个函数,昨天尝试了下,这句可以成功输入
const prop = Object.keys(ele).find(p => p.startsWith('__reactInternalInstance'));
ele._wrapperState.onChange(evt);
,但是报错
VM697 next.js:12 Uncaught Invariant Violation: ReactUpdates.asap: Can't enqueue an asap callback in a context whereupdates are not being batched.

console.log(ele._currentElement)
这个感觉是对的，你试试_currentElement.props.onChange吧。
都是大佬
