首先,我要说我知道此站点上至少还有十个其他几乎相同的问题。我看到了所有这些内容,并尝试了许多答案,但问题仍然存在,可能是因为我试图以错误的方式实现答案。无论如何,只要我在一个MAC输入中插入一个字符,它就会失去焦点。接下来是带有所述输入和onChange方法的代码段。

            {
                user.MACs.map
                (
                    (MAC, index) =>
                    {
                        return (
                            <div className = "singleMAC" key = {"singleMAC"+index}>
                                <label htmlFor = "MAC">MAC {index+1}</label>
                                <input
                                    form = "userEdit"
                                    className = "MACInput"
                                    value = {MAC || ""}
                                    placeholder = "MAC"
                                    onChange = {(e) => handleChangeMAC (index, e)}
                                />
                                <button
                                className = "buttonMACRemove"
                                type = "button"
                                onClick = {() => handleRemoveMAC (index)}
                                >
                                    X
                                </button>
                            </div>
                        );
                    }
                )
            }

然后...

function handleChangeMAC (index, e)
{
    const values = [...user.MACs];
    values[index] = e.target.value;
    var newUser = Object.assign ({}, user);
    newUser.MACs = values;
    setUser (newUser);
}
