为什么当我点击“添加到购物车”时，即使我点击了很多次，我也只得到一次更改，而且 cout 没有进入购物车，我该如何解决这个问题？我希望如果点击了按钮，那么“购物车”数组将保存该值，有一次更改，但只有一次更改，并且许多项目没有加起来

                    <div className="btn">
                      <img src={minus} onClick={this.props.handleMinus} />
                      <h1>{this.props.cout}</h1>
                      <img src={plus} onClick={this.props.handlePlus} />

    }else if(action.type === 'minus_button' && state.cout > 1){
        return {...state, cout: state.cout - 1}
    }
//I want if the button is clicked then the 'cart' array will hold the value,

      return state
