jquery, submit form when field loses focus

Question

How can I submit a form when a field (In this case the form only has one field) loses focus?

I tried this, but it\'s not working:

$(\"form\").submit(         


        

Answer 1

$('form :input').blur(function() {
    $(this).closest('form').submit();
});

Answer 2

What about this

var $yourForm = $('#form');

$yourForm.find('input').eq(0).blur(function() {

    $yourForm.submit();
});

Answer 3

Trigger the form's submit() event when the field loses focus. You can detect this by attaching a blur() event handler to it.

$("#field").blur(function() {
  $("#form").submit();
});

If you field doesn't have an ID or other means of easily identifying it (which I would recommend) you could also do something like this:

$("#form :input").blur(function() {
  $("#form").submit();
});

since there's only one field.
