function save()
{
var data = document.getElementById('number').value
var date = document.getElementById('todaydate').value
database.ref('users/' + date).set({
data : data,
date : date
})
alert('Saved')
}
function get() {
var username = document.getElementById('todaydate').value
var user_ref = database.ref('users/' + date)
user_ref.on('value', function(snapshot) {
var data = snapshot.val()
document.getElementById('number').value = snapshot.val().data;
})
