What methods can I use to enable web browsers to remember form field data that is not transmitted in the usual manner?

The code provided here is almost perfect in terms of functionality.

function post_form() {
    http=new XMLHttpRequest();

    http.onreadystatechange=function() {
        if (http.readyState==4 && http.status==200) some_div.innerHTML=http.responseText;
    };

    http.open("POST", some_action_url, false);
    http.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    http.send(my_form_query(some_form_element));
}

Everything works as expected, but there's a minor inconvenience. When the client reloads the page, they need to re-enter their name because the browser doesn't auto-complete the form fields.

Therefore, my query is how can I enable web browsers to remember form fields that are not submitted in a conventional manner?

Answer №1

Managing the draft saving process can be a bit intricate. One approach is to send the form fields to the server periodically to save them as a 'draft' whenever they are updated.

For instance:

setInterval(autoSave, 1000);
function autoSave() {
    if form is changed {
        use ajax to post form fields to server to save as a draft
    }
}

Then, when the user refreshes the page, you can populate the form fields with the saved draft.
