Usage Note:
———–
Do not use both ajaxSubmit and ajaxForm on the same form. These
functions are intended to be exclusive. Use ajaxSubmit if you want
to bind your own submit handler to the form. For example,

$(document).ready(function() {
$(‘#myForm’).bind(‘submit’, function(e) {
e.preventDefault(); // <– important
$(this).ajaxSubmit({
target: ‘#output’
});
});
});
