#this 是我想對道具執(zhí)行 Dispacth() 操作的地方我相信我正確連接了組件。第一個參數(shù)將 state 映射到 props，第二個參數(shù)映射到 dispatch。這樣當(dāng)我分派操作然后記錄 getState 時，我可以看到商店已更新。import React from "react";import { Modal, Button } from "react-bootstrap";import { connect } from "react-redux"function AddCart(props) {  console.log("AddCart Props", props);  function handleClick(e) {    e.preventDefault();    props.addtocard()    // props.addtocard((props.count * props.price))  }  return <Modal    {...props}    size="md"    aria-labelledby="contained-modal-title-vcenter"    centered  >    <Modal.Header closeButton    >      <Modal.Title id="contained-modal-title-vcenter">        Successful!          </Modal.Title>    </Modal.Header>    <Modal.Body>      <p>        <b>count:{props.count} size:{props.size}  x   title:{props.title} price:{(props.count * props.price).toFixed(2)}</b> added to your cart!          </p>    </Modal.Body>    <Modal.Footer >      <Button className="edit-btn" onClick={props.onHide}>Close</Button>      <Button className="edit-btn" href="/cart" onClick={handleClick}>Go to Cart</Button>    </Modal.Footer>  </Modal>}function mapDispatchToProps(dispatch, props) {  return {    addtocard: () => dispatch({ type: "ADD_ITEM", price: (props.count * props.price) })  }}export default connect(null, mapDispatchToProps)(AddCart);
