Alert方法重写

在正规项目中，总感觉alert框是非常难看的，但是有的时候又必须添加alert框来给用户一种警醒，废话不多说，先上图

下面是脚本代码，基于jQuery的

/// <summary>
/// 重写alert方法
/// </summary>
/// <param name="message">消息内容</param>
/// <param name="title">弹出窗标题</param>
/// <param name="title">点击确认按钮的回调函数</param>
window.alert = function (message, title, callbak) {
    /// <summary>
    /// 关闭Alert弹出窗
    /// </summary>
    (closeAlert = function () { $('#alert-window').remove(); })();
    var bg = $('<div class="alert-bg"></div>');
    var wnd = $('<div class="alert-wnd"><div class="alert-head"><center>'
                + (title || "提示信息")
                + '</center></div><div class="alert-body"><div class="alert-icon"><span></span></div><div class="alert-msg"><p>'
                + (message || '') + '</p></div></div><div class="alert-footer"><a class="btn btn-small" id="alert-confirm">确认</a></div></div>');
    window.top.$(document.body).append($('<div id="alert-window"></div>').append(bg).append(wnd).delegate('#alert-confirm', 'click', function () { closeAlert(); callbak && callbak(); }));
};

下面是css代码：

.btn {
    background-color: #F5F5F5;
    background-image: linear-gradient(to bottom, #FFFFFF, #E6E6E6);
    background-repeat: repeat-x;
    border-bottom: 0 none #B3B3B3;
    border-radius: 4px;
    border-right: 0 none #E6E6E6;
    border-top: 0 none #E6E6E6;
    box-shadow: 0 1px 0 rgba(255, 255, 255, 0.2) inset, 0 1px 2px rgba(0, 0, 0, 0.05);

对了还有一个资源文件

当加上上述代码到你的工程中，普通的alert方法就会产生如图的效果。这样alert的样式就随心所欲了。

现在还有没解决的问题是，这种alert框不能像浏览器自带的alert框那样停止脚本的运行，有没有完美的解决方案呢？
