jquery overlay close after submit a form with ajax

Hi I've tried everything, before asking you guys:

$(document).ready(function() {
var triggers = $("a[rel]").overlay({
    expose: {
        color: '#212121',
        loadSpeed: 200,
        opacity: 0.9
    },
    api: true,
    closeOnClick: true
});
});

$(document).ready(function(){

        $('#open_library').click(function (e) {     
            $('#OpenLib').slideToggle('slow');
            e.preventDefault();
            return false;
        });


    $forms = $('#library');
$forms.bind('submit', function(){
        var $button = $('button',this).attr('disabled',true);
        var params = $(this.elements).serialize();

        var self = this;
        $.ajax({
            type: 'POST',
            url: this.action,
            data: params,

        beforeSend: function(){
                $('#text_lib').show();

                $('#text_lib').html("Loading...");
            },
            success: function(txt){

                $button.attr('disa开发者_Python百科bled',false);

                $('#text_lib').html(txt);

                self.overlay().close();

                self.reset();
            },

            error: function(txt){
                $('#text_lib').html(txt);
            }
        })
        return false;
    });
});

Very simple.

self.overlay().close();

change to

$('#OpenLib').hide();

This is basic hiding.

If you using some plungin, then you shuld check out documentation of it. But i think triggers.close() will work.
