How to send values from LocalStorage to Flask @app.route()?

Solution


  Write Something & Post!

function submitForm()
{
    let name = localStorage.getItem('username');

    // set the value of the hidden input
    document.getElementById("username").value = name;

    // submit the form
    document.getElementById("post-form").submit();
}

document.addEventListener('DOMContentLoaded', function() {
    let name = localStorage.getItem('username');

    // set the value of the hidden input
    document.getElementById("username").value = name;
})
