Discussion on: Building a serverless contact form with AWS Lambda and AWS SES

Where is this here living? When I set it up and I test with the CURL command everything works flawlessly. But when I try to hit the submit button on the front end nothing happens?

const form = document.getElementById('contactForm')
const url = 'https://{id}.execute-api.{region}.amazonaws.com/{stage}/email/send'
const toast = document.getElementById('toast')
const submit = document.getElementById('submit')

function post(url, body, callback) {
var req = new XMLHttpRequest();
req.open("POST", url, true);
req.setRequestHeader("Content-Type", "application/json");
req.addEventListener("load", function () {
if (req.status < 400) {
callback(null, JSON.parse(req.responseText));
} else {
callback(new Error("Request failed: " + req.statusText));
}
});
req.send(JSON.stringify(body));
}
function success () {
toast.innerHTML = 'Thanks for sending me a message! I\'ll get in touch with you ASAP. :)'
submit.disabled = false
submit.blur()
form.name.focus()
form.name.value = ''
form.email.value = ''
form.content.value = ''
}
function error (err) {
toast.innerHTML = 'There was an error with sending your message, hold up until I fix it. Thanks for waiting.'
submit.disabled = false
console.log(err)
}

form.addEventListener('submit', function (e) {
e.preventDefault()
toast.innerHTML = 'Sending'
submit.disabled = true

const payload = {
name: form.name.value,
email: form.email.value,
content: form.content.value
}
post(url, payload, function (err, res) {
if (err) { return error(err) }
success()
})
})
