我无法链接验证和表单提交需要帮助设置变量真或假，以便不发送空表格吗？

问题描述

const form = document.querySelector('.form__contact');
const name = document.querySelector('input[name=name]');
const email = document.querySelector('input[name=email]');
const btnSubmit = document.querySelector('.btn-submit')

两场验证功能

function checkInputs() {
    let nameValue = name.value.trim();
    let emailValue = email.value.trim();

    if (nameValue === '') {
        setErrorFor(name,'Name cannot be blank');

    } else if (!isName(emailValue)) {
        setErrorFor(name,'Not a valid name');
    } else {
        setSuccessFor(name);
    }
    if (emailValue === '') {
        setErrorFor(email,'Email cannot be blank');

    } else if (!isEmail(emailValue)) {
        setErrorFor(email,'Not a valid email');

    } else {
        setSuccessFor(email);
    }
}
function setErrorFor(input,message) {
    const inputBox = input.parentElement;
    const errorMessage = inputBox.querySelector('.errors');
    inputBox.className = 'form__field error';
    errorMessage.textContent = message;
}
function setSuccessFor(input) {
    const inputBox = input.parentElement;
    const errorMessage = inputBox.querySelector('.errors');
    inputBox.className = 'form__field success';
    errorMessage.textContent = "";
}

现场验证功能

function isName(name) {
    let regExpName = /^[]{}?/;
    return regExpName.test(name);
}
function isEmail(email) {
    let regExpEmail = /[])?/;
    return regExpEmail.test(email);
}

serialize-此函数生成一个字符串以发送到服务器。函数已经准备好了，很大，所以我没有把所有的东西都扔在后面

function serialize(form) {
    if (!form || form.nodeName !== "FORM") {
        return false;
    }
    -- ----   - - - - -
}

并提交自己

btnSubmit.addEventListener('click',event => {
    event.preventDefault();

在这里，需要使用“ if else”或“ const isValidate = false”的任何其他内容

    checkInputs();
    console.log(serialize(form));

});

解决方法

如果验证错误，则“返回假”，请尝试以下操作：

function checkInputs() {
  let nameValue = name.value.trim();
  let emailValue = email.value.trim();

  if (nameValue === "") {
    setErrorFor(name,"Name cannot be blank");
    return false; // return false
  } else if (!isName(emailValue)) {
    setErrorFor(name,"Not a valid name");
    return false; // return false
  } else {
    setSuccessFor(name);
  }
  if (emailValue === "") {
    setErrorFor(email,"Email cannot be blank");
    return false; // return false
  } else if (!isEmail(emailValue)) {
    setErrorFor(email,"Not a valid email");
    return false; // return false
  } else {
    setSuccessFor(email);
  }

  return true; // default true
}
const isValidate = checkInputs();
if (isValidate) {
  console.log(serialize(form));
}
