I try to create form for POST the new user but have a problem. I use the bootstrap form validation (Browser defaults). Have a button:
<button class="btn btn-primary btn-addUser" type="submit">Add User</button>
This button also has the function of creating a new post based on the data from the input:
const addUsersBtn = document.querySelector(".btn-addUser");
// post add button in html
addUsersBtn.addEventListener("click", postNewUser);
// Post a user
function postNewUser(e) {
e.preventDefault();
// write value from form inputs
const name = form.elements.namedItem("name").value;
const username = form.elements.namedItem("username").value;
const email = form.elements.namedItem("email").value;
const phone = form.elements.namedItem("phone").value;
const website = form.elements.namedItem("website").value;
// create our user object from data recorded in variables from form inputs
const newPost = {
name: name,
username: username,
email: email,
phone: phone,
website: website,
user_id: `id_${Math.random() * Math.random()}`,
};
// create a post
createPost(newPost, (response) => {
const card = newPostTemplate(response);
container.insertAdjacentElement("afterbegin", card);
form.reset();
initPopovers();
});
}
But if i use the function postNewUser validation has not work. If i delete the "btn-addUser" class from button validation works. My code from addUser.js file:
// получаем нашу форму
const form = document.forms["addUser"];
// create a “create post” function
function createPost(body, callback) {
return new Promise((resolve, reject) => {
const request = new XMLHttpRequest();
request.open("POST", "https://jsonplaceholder.typicode.com/posts");
request.addEventListener("load", () => {
const response = JSON.parse(request.responseText);
// console.log(response);
if (request.status >= 400) {
reject(request.response);
} else {
resolve(request.response);
}
callback(response);
});
request.setRequestHeader("Content-type", "application/json; charset=UTF-8");
request.send(JSON.stringify(body));
});
}
// template for the post in which it will be built
function newPostTemplate(post) {
const card = document.createElement("div");
card.classList.add("card");
const cardBody = document.createElement("div");
cardBody.classList.add("card-body");
const userBtn = document.createElement("button");
userBtn.setAttribute("type", "button");
userBtn.classList.add("btn", "btn-info", "btn-lg");
userBtn.setAttribute("data-bs-toggle", "popover");
userBtn.setAttribute("data-bs-html", "true");
userBtn.setAttribute(
"data-bs-title",
"Additional information about the user: "
);
userBtn.setAttribute(
"data-bs-content",
`Username: ${post.username}<br/>Email: ${post.email}<br/>Phone: ${post.phone}<br/> Website: ${post.website}`
);
const title = document.createElement("h5");
title.classList.add("card-title");
title.textContent = post.name;
userBtn.appendChild(title);
cardBody.appendChild(userBtn);
card.appendChild(cardBody);
return card;
}
// button to add post in html
addUsersBtn.addEventListener("click", postNewUser);
// function Post user
function postNewUser(e) {
e.preventDefault();
// write value from form inputs
const name = form.elements.namedItem("name").value;
const username = form.elements.namedItem("username").value;
const email = form.elements.namedItem("email").value;
const phone = form.elements.namedItem("phone").value;
const website = form.elements.namedItem("website").value;
// create our user object from data recorded in variables from form inputs
const newPost = {
name: name,
username: username,
email: email,
phone: phone,
website: website,
user_id: `id_${Math.random() * Math.random()}`,
};
// create a post
createPost(newPost, (response) => {
const card = newPostTemplate(response);
container.insertAdjacentElement("afterbegin", card);
form.reset();
initPopovers();
});
}
I wanna ask some questions:
e.preventDefault()
in your submit event handler likely prevents browser to automatically perform its built-in validation checks when the form attempts to submit. You should manuallly check if form is valid using form.checkValidity()
like this:
function postNewUser(e) {
e.preventDefault();
if (form.checkValidity()) {
// Form is valid, proceed with creating the new user
// Add your custom logic here
} else {
// Form is invalid, trigger validation UI
// form.classList.add("was-validated");
}
}
Make sure your form has the necessary Bootstrap validation attributes and classes, such as novalidate on the form element and the appropriate validation classes on the form inputs.
