One way to write javascript to capture data from a form and save it to a database is to use the fetch API. You can create a function that takes the form element as an argument and uses the FormData object to get the form data. Then you can use the fetch method to send a POST request to the server with the form data as the body. The server can then process the request and save the data to the database. Here is an example of such a function:
function submitForm(form) {
// get the form data
let formData = new FormData(form);
// send a POST request to the server
fetch(‘/save’, {
method: ‘POST’,
body: formData
})
.then(response => response.json())
.then(data => {
// handle the response data
console.log(data);
})
.catch(error => {
// handle the error
console.error(error);
});
}
Hopefully this simple code sample will send you in the right direction for this common request. As I come across coding tasks that I find useful and interesting I will try to continue to share here on the blog. Happy Coding 🙂
