jquery自定义插件――window的实现【示例代码】

本例子实现弹窗的效果：

1、jquery.show.js

/* 
 * 实现功能：点击在鼠标位置显示div 
 * 版本序号：1.0 
 */
(function($){ 
  $.fn.showDIV = function(options){ 
    var defaults = {}; 
    var options = $.extend(defaults, options); 
    var showdiv=$(this); 
    var close, title, content; 
    close=$("

"); title=$(" 
"); content=$(" 
"); showdiv.html(""); showdiv.append(close); showdiv.append(title); showdiv.append(content); close.html("X"); title.html(options.title); content.html(options.content); showdiv.css("display","block"); showdiv.css("position","absolute"); showdiv.css("left",($(window).width()-options.width)/2+"px"); showdiv.css("top",($(window).height()-options.height)/2+"px"); showdiv.css("width",options.width); showdiv.css("height",options.height); close.bind("click",function(){ showdiv.css("display","none"); }); }; })(jQuery);

2、jquery.showdiv.css

body div 
{ 
  font-size:12px; 
  text-align:center; 
} 
#container 
{ 
  background-color:#CCC; 
  border:1px solid #000; 
  width:1024px; 
  height:600px; 
} 
#showdiv 
{ 
  background-color:#FF0; 
  width:100px; 
  height:100px; 
  display:none; 
  z-index:99; 
} 
.title 
{ 
  padding:10px; 
  background:#F39; 
  font-weight:bold; 
  text-align:center; 
  color:#FFF; 
} 
.close 
{ 
  margin:5px; 
  position:absolute; 
  right:0px; 
  top::0px; 
  padding:5px; 
  color:#000; 
  background:#FFF; 
} 
.close:hover 
{ 
  cursor:pointer; 
  background:#CCC; 
} 
.content 
{ 
  text-align:left; 
  padding:10px; 
}

3、demo.html

<script type="text/javascript" src="jquery/jquery.min.js"></script> 
<script type="text/javascript" src="jquery/jquery.showdiv.js"></script> 
<script type="text/javascript"> 
  $(document).ready(function (){  
    $('#show').bind("click", function(evt){ 
      var showdiv = $('#showdiv').showDIV({ 
        width:400, 
        height:200, 
        title:"我不是黄蓉", 
        content:"我不是黄蓉<BR>我不会武功<BR>我只要靖哥哥<BR>完美的爱情"
      }); 
    }); 
  }); 
</script> 
 
 
 
<INPUT id=show value=显示 type=button name=showDiv>

实现后的效果如下：
