分享一個(gè)灰常簡(jiǎn)單好用的jQuery彈出層插件:jquery.artwl.thickbox.js

最終效果：

插件原理

　　所有彈出層的原理都差不多，就是用一個(gè)全屏半透明DIV做遮罩層，在這個(gè)遮罩層上再顯示出一個(gè)層放要顯示的內(nèi)容，其他的就是CSS的運(yùn)用了。

　　本插件為了使用簡(jiǎn)單，把JS跟CSS封裝在了一個(gè)JS文件(插件)中，所以使用起來(lái)非常方便，做到了一行代碼調(diào)用。

插件源代碼

　　插件(jquery.artwl.thickbox.js)的源碼如下：

                    width = $(window).width() > 600 ? 600 : $(window).width() - 40;
                    $("#artwl_boxcontain").css("width", width + "px").css("top", ($(window).height() - height) / 2).css("left", ($(window).width() - width) / 2).show();
                    $("#artwl_mask").css("width", $(window).width() + "px").css("height", $(window).height() + "px").css("background", "#888");
                    $("#artwl_close").css("top", "30px").css("right", "30px").css("font-size", "20px").text("關(guān)閉");
                }
            });
            $("#artwl_close").click(function () {
                $("#artwl_mask").hide();
                $("#artwl_boxcontain").hide();
            });
        },
        artwl_close:function(options){
            options=$.extend({
                callback:null
                },options);
            $("#artwl_mask").hide();
            $("#artwl_boxcontain").hide();
            if(options.callback!=null){
                options.callback();
            }
        }
    });
})(jQuery);

　　調(diào)用也非常簡(jiǎn)單，在頁(yè)面引入此JS文件后，在頁(yè)面加載方法中調(diào)用如下代碼即可：

$.artwl_bind({ showbtnid: "btn_show", title: "From Cnblogs Artwl", content: $("#Content").html() });

　　這三個(gè)參數(shù)非常簡(jiǎn)單，第一個(gè)是彈出層觸發(fā)事件的元素ID，第二個(gè)為彈出層的標(biāo)題，第三個(gè)為彈出層的內(nèi)容

注意事項(xiàng)

　　為了使用方便，本插件把JS跟CSS寫在了一個(gè)文件中，如果要調(diào)整彈出層的樣式可以修改如下CSS即可。

　　插件CSS代碼：

html, body, h1, h2, h3, h4, h5 {
    margin: 0px;
    padding: 0px;
}
#artwl_mask {
    background - color: #000;
    position: absolute;
    top: 0px;
    left: 0px;
    width: 100%;
    height: 100%;
    opacity: 0.5;
    filter: alpha(opacity= 50);
    display: none;
}
#artwl_boxcontain {
    margin: 0 auto;
    position: absolute;
    z - index: 2;
    line - height: 28px;
    display: none;
}
#artwl_showbox {
    padding: 10px;
    background: #FFF;
    border - radius: 5px;
    margin: 20px;
    min - width: 300px;
    min - height: 200px;
}
#artwl_title {
    position: relative;
    height: 27px;
    border - bottom: 1px solid #999;
}
# artwl_close {
    position: absolute;
    cursor: pointer;
    outline: none;
    top: 0;
    right: 0;
    z - index: 4;
    width: 42px;
    height: 42px;
    overflow: hidden;
    background - image: url(/Images/feedback - close.png);
    _background: none;
}
#artwl_message {
    padding: 10px 0px;
    overflow: hidden;
    line - height: 19px;
}
