Controller:
def VcodeToDbAndMail():
return 1
Javascript:
<script>
let x = 0
function showCode(data) {
x = parseInt(data);
$('#code').css('visibility', 'visible');
}
jQuery(function() {
jQuery('#myform').submit(function(e) {
e.preventDefault();
ajax('{{=URL("VcodeToDbAndMail")}}', ['email'], showCode);
});
});
</script>
The third argument of the ajax() function can be a callback function that
takes the response from the server. Above, the server simply returns the
value "1", which gets passed to the showCode() callback, which sets the
value of x and then makes the "#code" element visible.
