REACT 多步骤形式：下一步按钮不起作用，第一个圆圈已经是绿色的

Question

我是 REACT 的初学者，我正在尝试在 React 中创建一个多步骤表单。如何隐藏第一页的返回按钮（请看图片）。

export default function StepperControl({ handleClick, currentStep, steps }) {
    return (
        <div className="container mt-4 mb-8 flex justify-around">
            <button
                onClick={() => handleClick()}
                className={`cursor-pointer rounded-xl border-2 border-slate-300 bg-white py-2 px-4 font-semibold uppercase text-slate-400 transition duration-200 ease-in-out 
                hover:bg-slate-700 hover:text-white  ${currentStep === 1 ? " cursor-not-allowed opacity-50 " : ""
                    }`}
            >

                Back
            </button>

            <button
                onClick={() => handleClick("next")}
                className="cursor-pointer rounded-lg bg-blue-700 py-2 px-4 font-semibold uppercase text-white transition duration-200 ease-in-out hover:bg-slate-700 hover:text-white"
            >
                {currentStep === steps.length - 1 ? "Confirm" : "Next"}
            </button>
        </div>
    );
}

非常感谢您的帮助

我想这就是你需要的。

export default function StepperControl({ handleClick, currentStep, steps }) {
    return (
        <div className="container mt-4 mb-8 flex justify-around">
            {
                currentStep > 1 &&
                    <button
                        onClick={() => handleClick()}
                        className={`cursor-pointer rounded-xl border-2 border-slate-300 bg-white py-2 px-4 font-semibold uppercase text-slate-400 transition duration-200 ease-in-out 
                        hover:bg-slate-700 hover:text-white cursor-not-allowed opacity-50`}
                    >

                        Back
                    </button>
            }

            <button
                onClick={() => handleClick("next")}
                className="cursor-pointer rounded-lg bg-blue-700 py-2 px-4 font-semibold uppercase text-white transition duration-200 ease-in-out hover:bg-slate-700 hover:text-white"
            >
                {currentStep === steps.length - 1 ? "Confirm" : "Next"}
            </button>
        </div>
    );
}

此外，您应该将 currentStep 作为 number/integer 而不是对象发送。
