Jquery submit () not working with descriptor?

Question

Why does it work:

    $("form[data-remote].edit_item").submit();

But is that not so?

    $("form[data-remote].edit_item").submit(function() {
             alert('goo')
    });

Answer 1

In this case, you raise an event submit:

$("form[data-remote].edit_item").submit();

With this, you attach a handler to the event submit:

$("form[data-remote].edit_item").submit(function() {
   alert('goo');
});

---

In the second, you say “warning when an event occurs submit” ... you don’t say “hey, obey”, for this you still need to call .submit()or what is the shortcut for: .trigger("submit")... like this:

$("form[data-remote].edit_item").submit(function() {
   alert('goo');
}).submit();

... but at this moment, why not just notify separately? eg:

$("form[data-remote].edit_item").submit();
alert('goo');

Answer 2

You are missing a semicolon after calling an alert.

Answer 3

alert()?

$("form[data-remote].edit_item").submit(function(e) {
     e.preventDefault();
     alert('goo');
});
