jquery tools系列 expose 学习

如overlay的学习，首先给出操作的html目标代码：


代码如下:

<div id="test">
    expose test!
</div>

<div style="margin:0 auto;width:300px">
    <img src="http://flowplayer.org/tools/img/expose/ball_large.png" id="ball" style="width:130px" />
</div>
<div style="position:relative;z-index:10000">
<button type="button" id="btn_open">open div</button>
<button type="button" id="btn_close">close div</button>
</div>

该功能是通过jqueryObject.expose()方法来实现的，其具体实现方式如下：
$("jquery selector").expose({config object}) //该方法通过配置对象将来定制expose的显示。
以下代码为配置参数说明描述：

var testApi=$("#test").expose({
            color:'#44f',
            opacity:0.5,
            loadSpeed:2000,
            closeSpeed:3000,
            closeOnClick:false,
            closeOnEsc:false,
            api: true,
            lazy:true,
            onBeforeLoad:function(){
                alert("before load!");
            },
            onLoad:function(){
                alert("onLoad!");
            },
            onBeforeClose:function(){
                alert("mask-background:"+this.getMask().css("color")+",exposeId:"+this.getExposed().attr("id")
                                    +"\n expose color:"+this.getConf().color);
                //alert("Before close!");
            },
            onClose:function(){
                alert("Close!");
            }

});

$("#test").click(function() {
        testApi.load();
    });

$("#btn_open").click(function(){
        testApi.load();
    });
    $("#btn_close").click(function(){
        testApi.close();
    });

alert("test is load:"+testApi.isLoaded());

$("#ball").expose({
        //此处通过maskId中样式的backgroundcolor来设置color属性
        maskId:'mask',
        opacity:0.5,
        closeSpeed:'slow',
        onBeforeLoad:function(){
            this.getExposed().animate({width:298});
        },
        onBeforeClose:function(){
            this.getExposed().animate({width:130});    
        }

}).click(function(){
        $(this).expose().load();
    });

最后，给出完整示例代码及该功能得部分demo图片：
