Jquery运行我的ziptastic慢

Question

当我的客户输入他们的邮政编码时，输出数据（城市和州）的加载速度非常慢。他们必须非常慢地填写邮政编码，以便显示城市和州的数据字段。这里的任何帮助都很棒，是网站的功能代码。

(function( $ ) {
    var requests = {};
    var zipValid = {
            us: /[0-9]{5}(-[0-9]{4})?/
    };

    $.ziptastic = function(zip, callback){
            // Only make unique requests
            if(!requests[zip]) {
                    requests[zip] = $.getJSON('http://zip.elevenbasetwo.com/v2/US/' + zip);
            }

            // Bind to the finished request
            requests[zip].done(function(data) {
                    callback(data.country, data.state, data.city, zip);
            });

            // Allow for binding to the deferred object
            return requests[zip];
    };

    $.fn.ziptastic = function( options ) {
            return this.each(function() {
                    var ele = $(this);

                    ele.on('keyup', function() {
                            var zip = ele.val();

                            // TODO Non-US zip codes?
                            if(zipValid.us.test(zip)) {
                                    $.ziptastic(zip, function(country, state, city) {
                                            // Trigger the updated information
                                            ele.trigger('zipChange', [country, state, city, zip]);
                                    })
                            }
                    });
            });
    };
})( jQuery );
