jQuery脚本运行不正常，警报未显示

Question

I have this jquery script:

$('input[name="add-post"]').on('click', function(form) {
    form.preventDefault();
    for ( instance in CKEDITOR.instances )
    CKEDITOR.instances[instance].updateElement();
    $.ajax({
        type: 'POST',
        url: 'add-post',
        data: $('form.new-post').serialize(),
        dataType: 'json',
        succes: function(data)
        {
            alert('123');

        },
        error: function(data)
        {
            alert('321');
        }
    });
});

And technically it works as it should. Ajax goes to add-post php script, post is added to database. Whole PHP script is done as it should.

But

alert('123');

Alert doesn't show up. No 123. No 321. There is no alert.

Why this doesn't work? Despite PHP's script by ajax did all good.

(note: no information in console chrome after submit)

Some additional information:

When duplicate post is submitted (already exist in DB) 321 alert is shown.

But still no 123 alert. When it is success.

Answer 1

use this

success: function(data)
