[JQuery / Ajax]降低点击延迟

Question

我的Ajax功能有点问题：点击按钮寄存器后，我无法降低延迟。

我首先点击提交表单上的按钮，然后等待3秒，然后启动：＆＃34;登录＆＃34; - 很少延迟 - 显示信息。

如何使它像点击该按钮一样，直接启动ajax功能：＆＃34;登录＆＃34; - 稍微延迟（对于加载图像） - 显示消息？

我的Ajax

$('document').ready(function(){

$(document).on('submit', '#formRegister', function(e) {
    e.preventDefault();

    $('input+small').text('');
    $('input').parent().removeClass('has-error');
    $.ajax({
        method: $(this).attr('method'),
        url: $(this).attr('action'),
        data: $(this).serialize(),
        dataType: "json"
    })
        .done(function(data){
            $('#btn-signup').html('<img src="images/ajax-loader.gif" /> &nbsp; signing in...').prop('disabled', true);
            // Loading gif.
            $('input[type=text],input[type=password]').prop('disabled', true);
            // Disable the input text and password

            setTimeout(function(){

                $('#error_register').slideDown('fast', function(){
                    $messageRegister = "The message";
                    $('#error_register').html('<div class="alert alert-info">'+$messageRegister+'</div>');
                    // Show the message from the variable.
                    $("#formRegister").trigger('reset');
                    // Reset the form
                    $('input[type=email],input[type=password]').prop('disabled', false);
                    // Enable the input text, email, password
                    $('#btn-signup').html('Submit').prop('disabled', false);
                }).delay(3000).slideUp('fast');
                // Hide the div that contain the message.
                window.setTimeout(function(){location.reload()},4500);
                // Reload page after 4.5 seconds.

            },3000);

        })
        .fail(function(data) {
            $.each(data.responseJSON, function (key, value) {
                var input = '#formRegister input[name=' + key + ']';
                $(input + '+small').text(value);
                $(input).parent().addClass('has-error');
                $('#btn-signup').html('Submit').prop('disabled', false);
            });
        });
});

}）
