Answer 1

您可以创建自己的const mapStateToProps = (state, props) => { return { mylist: state.mylist, }; }; const mapDispatchToProps = (dispatch, props) => { return { refreshStart: () => dispatch(recentRefreshStart()), mylistLoad: () => dispatch(mylistLoad()), }; }; export default connect(mapStateToProps, mapDispatchToProps)(MyList);功能 -

on()

或者您可以查看对象函数的原型 - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/prototype

document.getElementById("id").onclick = doSomething;
