1.添加一個jq擴展

   <script type="text/javascript">

         (function ($) {

            $.extend({

                /**

                * 调用方法： var timerArr = $.blinkTitle.show();

                *            $.blinkTitle.clear(timerArr);

                */

                blinkTitle: {

                    show: function () {    //有新消息时在title处闪烁提示

                        var step = 0, _title = document.title;

                        var timer = setInterval(function () {

                            step++;

                            if (step == 3) { step = 1 };

                            if (step == 1) { document.title = '【　　　】' + _title };

                            if (step == 2) { document.title = '【新消息】' + _title };

                        }, 500);

                        return [timer, _title];

                    },

                    /**

                    * @param timerArr[0], timer标记

                    * @param timerArr[1], 初始的title文本内容

                    */

                    clear: function (timerArr) {    //去除闪烁提示，恢复初始title文本

                        if (timerArr) {

                            clearInterval(timerArr[0]);

                            document.title = timerArr[1];

                        };

                    }

                }

            });

        })(jQuery);

2.方法調用

        jQuery(function ($) {

            var timerArr = $.blinkTitle.show();

            setTimeout(function () {        //此处是过一定时间后自动消失

                $.blinkTitle.clear(timerArr);

            }, 10000);

            //若认为操作消失，只需如此调用：    $.blinkTitle.clear(timerArr);

        });

3.說明

    其實是定時，換html 的title的內容。
