js右下角提示框代码
例子，右下角提示框的jquery插件 （popup.js）
//兼容ie6的fixed代码
//jQuery(function($j){
//$j('#pop').positionFixed()
//})
(function($j){
$j.positionFixed = function(el){
$j(el).each(function(){
new fixed(this)
})
return el;
}
$j.fn.positionFixed = function(){
return $j.positionFixed(this)
}
var fixed = $j.positionFixed.impl = function(el){
var o=this;
o.sts={
target : $j(el).css('position','fixed'),
container : $j(window)
}
o.sts.currentCss = {
top : o.sts.target.css('top'),
right : o.sts.target.css('right'),
bottom : o.sts.target.css('bottom'),
left : o.sts.target.css('left')
}
if(!o.ie6)return;
o.bindEvent();
}
$j.extend(fixed.prototype,{
ie6 : $.browser.msie && $.browser.version < 7.0,
bindEvent : function(){
var o=this;
o.sts.target.css('position','absolute')
o.overRelative().initBasePos();
o.sts.target.css(o.sts.basePos)
o.sts.container.scroll(o.scrollEvent()).resize(o.resizeEvent());
o.setPos();
},
overRelative : function(){
var o=this;
var relative = o.sts.target.parents().filter(function(){
if($j(this).css('position')=='relative')return this;
})
if(relative.size()>0)relative.after(o.sts.target)
return o;
},
initBasePos : function(){
var o=this;
o.sts.basePos = {
top: o.sts.target.offset().top - (o.sts.currentCss.top=='auto'?o.sts.container.scrollTop():0),
left: o.sts.target.offset().left - (o.sts.currentCss.left=='auto'?o.sts.container.scrollLeft():0)
}
return o;
},
setPos : function(){
var o=this;
o.sts.target.css({
top: o.sts.container.scrollTop() + o.sts.basePos.top,

})(jQuery)
jQuery(function($j){

//pop右下角弹窗函数
function Pop(title,url,intro){
this.title=title;
this.url=url;

this.hideTime=500;

//添加信息
this.addInfo();
//显示
this.showDiv();
//关闭
this.closediv();

Pop.prototype={
addInfo:function(){
$("#popTitle a").attr('href',this.url).html(this.title);
$("#popIntro").html(this.intro);
$("#popMore a").attr('href',this.url);
},
showDiv:function(time){
if (!($.browser.msie && ($.browser.version == "6.0") && !$.support.style)) {
$('#pop').slideDown(this.apearTime).delay(this.delay).fadeOut(400);;
} else{//调用jquery.fixed.js,解决ie6不能用fixed
$('#pop').show();
jQuery(function($j){
$j('#pop').positionFixed()
})
}
},
closeDiv:function(){
$("#popClose").click(function(){
$('#pop').hide();
}
