检查数据后如何发送表单?
How to send form after checking its data?
我正在尝试在提交数据之前检查表单数据。我已经完成了所有的控制,但我不知道如何提交表单。我试图搜索一些东西,但几乎都需要 jQuery,但我不会使用它。你能帮帮我吗?
form.forEach(e => {
e.addEventListener("submit", (e) => {
e.preventDefault();
if(checkInputs())
//send the fomr's data. But how?
})
});
function checkInputs(){
if(containerForm[1].classList.contains('hide')){
const username = document.getElementById("usernameSignIn");
const password = document.getElementById("passwordSignIn");
const usernameValue = username.value.trim();
const passwordValue = password.value;
let correctUser, correctPass = false;
if(username.value === '' || username.value === null){
printError(username, "Username cannot be blank");
} else {
printSucces(username);
correctUser = true;
}
if(passwordValue === '' || passwordValue === null){
printError(password, "Password cannot be blank");
} else if(passwordValue.length < 8 || !passwordCheck(passwordValue)){
printError(password, "Incorrect password");
}
if(passwordCheck(passwordValue)){
printSucces(password);
correctPass = true;
}
return correctUser && correctPass ? true : false;
}
}
function printError(input, error){
input.parentElement.classList = "row error";
input.parentElement.querySelector('.errorMessage').innerText = error;
}
function printSucces(input){
input.parentElement.classList = "row success";
input.parentElement.querySelector('.errorMessage').innerText = null;
}
function passwordCheck(password){
let regex = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*()+=-\?;,./{}|\":<>\[\]\\' ~_]).{8,}/;
return regex.test(password);
}
它看起来像:
form.forEach(e => {
e.addEventListener("submit", (e) => {
e.preventDefault();
if(checkInputs())
e.target.submit();
})
});
e.preventDefault();
会阻止表单提交,因此如果您希望提交表单,不要 这样做。
e.addEventListener("submit", (e) => {
if (!checkInputs())
e.preventDefault();
});
