分享一个灰常简单好用的jQuery弹出层插件:jquery.artwl.thickbox.js

最终效果:

插件原理

  所有弹出层的原理都差不多,就是用一个全屏半透明DIV做遮罩层,在这个遮罩层上再显示出一个层放要显示的内容,其他的就是CSS的运用了。

  本插件为了使用简单,把JS跟CSS封装在了一个JS文件(插件)中,所以使用起来非常方便,做到了一行代码调用。

插件源代码

  插件(jquery.artwl.thickbox.js)的源码如下:

/* File Created: 三月 1, 2012     Author:artwl  blog:http://artwl.cnblogs.com */
;(function ($) {
$.extend({
artwl_bind: function (options) {
options=$.extend({
showbtnid:"",
title:"",
content:""
},options);
var mask = '<div id="artwl_mask"></div>';
var boxcontain = '<div id="artwl_boxcontain">\
<a id="artwl_close" href="javascript:void(0);" title="Close"></a>\
<div id="artwl_showbox">\
<div id="artwl_title">\
<h2>\
Title</h2>\
</div>\
<div id="artwl_message">\
Content<br />\
</div>\
</div>\
</div>';
var cssCode = '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;}';
if ($("#artwl_mask").length == 0) {
$("body").append(mask + boxcontain);
$("head").append("<style type='text/css'>" + cssCode + "</style>");
if(options.title!=""){
$("#artwl_title").html(options.title);
}
if(options.content!=""){
$("#artwl_message").html(options.content);
}
}
$("#"+options.showbtnid).click(function () {
var height = $("#artwl_boxcontain").height();
var width = $("#artwl_boxcontain").width();
$("#artwl_mask").show();
$("#artwl_boxcontain").css("top", ($(window).height() - height) / 2).css("left", ($(window).width() - width) / 2).show();
if ($.browser.msie && $.browser.version.substr(0, 1) < 7) {
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("关闭");
}
});
$("#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);

  调用也非常简单,在页面引入此JS文件后,在页面加载方法中调用如下代码即可:

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

  这三个参数非常简单,第一个是弹出层触发事件的元素ID,第二个为弹出层的标题,第三个为弹出层的内容

注意事项

  为了使用方便,本插件把JS跟CSS写在了一个文件中,如果要调整弹出层的样式可以修改如下CSS即可。

  插件CSS代码:

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;
}

  另外,针对IE6不支持透明作了特殊处理,在IE6下显示为:

IE6

插件更新

  园友“技术宅男”发现了有滚动条时的bug,之前没考虑周全,修改后插件代码如下:

; (function ($) {
$.extend({
artwl_bind: function (options) {
options = $.extend({
title: "",
content: "",
width:"500px"
}, options);
var mask = '<div id="artwl_mask"></div>';
var boxcontain = '<div id="artwl_boxcontain">\
<a id="artwl_close" href="javascript:void(0);" title="Close"></a>\
<div id="artwl_showbox">\
<div id="artwl_title">\
<h2>\
正在加载,请稍后...</h2>\
</div>\
<div id="artwl_message">\
正在加载,请稍后...<br />\
</div>\
</div>\
</div>';
var cssCode = 'html, body, h1, h2, h3, h4, h5{margin: 0px;padding: 0px;}\
#artwl_mask{background-color: #000;position: absolute;top: 0px;left: 0px;width: 100%;height: 100%;opacity: 0.5;filter: alpha(opacity=50);display: none;}\
#artwl_boxcontain{margin: 0 auto;position: absolute;z-index: 2;line-height: 28px;display: none;}\
#artwl_showbox{padding: 10px;background: #FFF;border-radius: 5px;margin: 20px;min-width:300px;min-height:150px;}\
#artwl_title{position: relative;height: 27px;border-bottom: 1px solid #999;color:#444;font-size:14px;}\
#artwl_close{position: absolute;cursor: pointer;outline: none;top: 0;right: 0;z-index: 4;width: 42px;height: 42px;overflow: hidden;background-image: url(/Images/thickboxclose.png);_background: none;}\
#artwl_message{padding: 10px 0px;overflow: hidden;line-height: 19px;}';
if ($("#artwl_mask").length == 0) {
$("body").append(mask + boxcontain);
$("head").append("<style type='text/css'>" + cssCode + "</style>");
}
else{
$("#artwl_boxcontain").remove();
$("body").append(boxcontain);
}

if (options.title != "") {
$("#artwl_title").html(options.title);
}
if (options.content != "") {
$("#artwl_message").html(options.content);
}

if($(window).width()>parseInt(options.width)){
$("#artwl_boxcontain").css("width",options.width);
}
else{
$("#artwl_boxcontain").css("width",$(window).width()-40+"px");
}
var height = $("#artwl_boxcontain").height();
var width = $("#artwl_boxcontain").width();
$("#artwl_mask").css("height",$("body").height()>$(window).height()?$("body").height():$(window).height()+"px").show();

$("#artwl_boxcontain").css("top", ($(window).height() - height) / 2+$(document).scrollTop()).css("left", ($(window).width() - width) / 2).show();
if ($.browser.msie && $.browser.version.substr(0, 1) < 7) {
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("关闭");
}

$("#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);
