帮我找个js脚本的bug

  • 772

我为注册和登录表单编写了代码。最初您需要注册。表单检查“邮件”、“密码”字段中输入数据的有效性以及复选框中是否存在复选标记(据我所知,这里的代码在某处失败),然后单击“注册”按钮,输入的数据保存在 localStorage 中,注册表切换到登录表单。在登录表单中,还应检查字段,但已检查是否符合存储在 localStorage 中的数据。但是在单击复选框时,该脚本在注册表单中停止工作。请帮我找出错误。

    const checkbox1 = document.querySelector('#box1'); //вход
    const checkbox2 = document.querySelector('#box2'); //регистрация
    

    Если не ошибаюсь тут напутали checkbox1 и checkbox2. В форма регистрации у вас сейчас checkbox1, а должно быть checkbox2, поменяйте на checkbox2 и должно сохраниться в localStorage

    function checkboxValid() {
    if (!checkbox1.checked === false) {
    checkbox1.style.borderColor = 'black';
    errorpass3.style.display = 'none';
    c = true;
    } else {
    checkbox1.style.borderColor = 'red';
    errorpass3.style.display = 'initial';
    star3.style.color = 'red';
    c = false;
    }
    }
    checkbox1.addEventListener('change', checkboxValid);
