colortip是将标签中的title属性的值弹出显示的，默认情况是黄色的：

 <!DOCTYPE html>

 <html xmlns="http://www.w3.org/1999/xhtml">

 <head>

     <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

     <title></title>

     <!--css文件-->

     <link href="Colortip/styles.css" rel="stylesheet" />

     <link href="Colortip/colortip-1.0/colortip-1.0-jquery.css" rel="stylesheet" />

 </head>

 <body>

     <div style="text-align:center;margin-top:200px;"><a href="#" title="这是个大美女">美女</a></div>

     <div style="text-align:center;margin-top:250px;"><a href="#" title="这是个大美女" class="black">美女</a></div>

 </body>

 </html>

 <!--引入需要的js-->

 <script type="text/javascript" src="Script/jquery-1.11.0.js"></script>

 <script type="text/javascript" src="Colortip/colortip-1.0/colortip-1.0-jquery.js"></script>

 <script type="text/javascript" src="Colortip/script.js"></script>

通过查看这些设置，是在colortip-1.0-jquery.js文件中进行配置的：

(function($){

    $.fn.colorTip = function(settings){

        var defaultSettings = {

            color        : 'yellow',//默认颜色

            timeout        : 500

        }

        var supportedColors = ['red','green','blue','white','yellow','black'];//总共有6种主题的颜色

        /* Combining the default settings object with the supplied one */

        settings = $.extend(defaultSettings,settings);

        /*

        *    Looping through all the elements and returning them afterwards.

        *    This will add chainability to the plugin.

        */

        return this.each(function(){

            var elem = $(this);

            // If the title attribute is empty, continue with the next element

            if(!elem.attr('title')) return true;

            // Creating new eventScheduler and Tip objects for this element.

            // (See the class definition at the bottom).

            var scheduleEvent = new eventScheduler();

            var tip = new Tip(elem.attr('title'));

            // Adding the tooltip markup to the element and

            // applying a special class:

            elem.append(tip.generate()).addClass('colorTipContainer');

            // Checking to see whether a supported color has been

            // set as a classname on the element.

            var hasClass = false;

            for(var i=0;i<supportedColors.length;i++)

            {

                if(elem.hasClass(supportedColors[i])){

                    hasClass = true;

                    break;

                }

            }

            // If it has been set, it will override the default color

            if(!hasClass){

                elem.addClass(settings.color);

            }

            // On mouseenter, show the tip, on mouseleave set the

            // tip to be hidden in half a second.

            elem.hover(function(){

                tip.show();

                // If the user moves away and hovers over the tip again,

                // clear the previously set event:

                scheduleEvent.clear();

            },function(){

                // Schedule event actualy sets a timeout (as you can

                // see from the class definition below).

                scheduleEvent.set(function(){

                    tip.hide();

                },settings.timeout);

            });

            // Removing the title attribute, so the regular OS titles are

            // not shown along with the tooltips.

            elem.removeAttr('title');

        });

    }

    /*

    /    Event Scheduler Class Definition

    */

    function eventScheduler(){}

    eventScheduler.prototype = {

        set    : function (func,timeout){

            // The set method takes a function and a time period (ms) as

            // parameters, and sets a timeout

            this.timer = setTimeout(func,timeout);

        },

        clear: function(){

            // The clear method clears the timeout

            clearTimeout(this.timer);

        }

    }

    /*

    /    Tip Class Definition

    */

    function Tip(txt){

        this.content = txt;

        this.shown = false;

    }

    Tip.prototype = {

        generate: function(){

            // The generate method returns either a previously generated element

            // stored in the tip variable, or generates it and saves it in tip for

            // later use, after which returns it.

            return this.tip || (this.tip = $('<span class="colorTip">'+this.content+

                                             '<span class="pointyTipShadow"></span><span class="pointyTip"></span></span>'));//显示的消息提示框是一个span标签

        },

        show: function(){

            if(this.shown) return;

            // Center the tip and start a fadeIn animation

            this.tip.css('margin-left',-this.tip.outerWidth()/2).fadeIn('fast');

            this.shown = true;

        },

        hide: function(){

            this.tip.fadeOut();

            this.shown = false;

        }

    }

})(jQuery);

通过该js文件，可见该插件主要是在title属性中设置显示信息的。

总结

colortip用起来还是非常简单的，在想要提示信息的地方加个带title属性的a标签就可以了，不过有点差强人意的地方，如果其他的标签例如按钮，加一个title，就会提示错误。
