就是说，有些人是不是很懒惰拉上去的，

就用这东西，就可以返回上面去。

1. 首先，设计 → 页面元素 → 添加小工具 → 添加 HTML/JavaScript

2. 添加以下代码：

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>

<script type="text/javascript">

var scrolltotop={

setting: {startline:100, scrollto: 0, scrollduration:1000, fadeduration:[500, 100]},

controlHTML: '<img src="图画 URL" style="filter:alpha(opacity=70); -moz-opacity:0.1; width:33px; height:47px" />',

controlattrs: {offsetx:40, offsety:70},

anchorkeyword: '#top',

state: {isvisible:false, shouldvisible:false},

scrollup:function(){

if (!this.cssfixedsupport)

this.$control.css({opacity:0})

var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto)

if (typeof dest=="string" && jQuery('#'+dest).length==1)

dest=jQuery('#'+dest).offset().top

else

dest=0

this.$body.animate({scrollTop: dest}, this.setting.scrollduration);

},

keepfixed:function(){

var $window=jQuery(window)

var controlx=$window.scrollLeft() + $window.width() - this.$control.width() - this.controlattrs.offsetx

var controly=$window.scrollTop() + $window.height() - this.$control.height() - this.controlattrs.offsety

this.$control.css({left:controlx+'px', top:controly+'px'})

},

togglecontrol:function(){

var scrolltop=jQuery(window).scrollTop()

if (!this.cssfixedsupport)

this.keepfixed()

this.state.shouldvisible=(scrolltop>=this.setting.startline)? true : false

if (this.state.shouldvisible && !this.state.isvisible){

this.$control.stop().animate({opacity:1}, this.setting.fadeduration[0])

this.state.isvisible=true

}

else if (this.state.shouldvisible==false && this.state.isvisible){

this.$control.stop().animate({opacity:0}, this.setting.fadeduration[1])

this.state.isvisible=false

}

},

init:function(){

jQuery(document).ready(function($){

var mainobj=scrolltotop

var iebrws=document.all

mainobj.cssfixedsupport=!iebrws || iebrws && document.compatMode=="CSS1Compat" && window.XMLHttpRequest //not IE or IE7+ browsers in standards mode

mainobj.$body=(window.opera)? (document.compatMode=="CSS1Compat"? $('html') : $('body')) : $('html,body')

mainobj.$control=$('<div id="topcontrol">'+mainobj.controlHTML+'</div>')

.css({position:mainobj.cssfixedsupport? 'fixed' : 'absolute', bottom:mainobj.controlattrs.offsety, right:mainobj.controlattrs.offsetx, opacity:0, cursor:'pointer'})

.attr({title:'Back to Top'})

.click(function(){mainobj.scrollup(); return false})

.appendTo('body')

if (document.all && !window.XMLHttpRequest && mainobj.$control.text()!='')

mainobj.$control.css({width:mainobj.$control.width()})

mainobj.togglecontrol()

$('a[href="' + mainobj.anchorkeyword +'"]').click(function(){

mainobj.scrollup()

return false

})

$(window).bind('scroll resize', function(e){

mainobj.togglecontrol()

})

})

}

}

scrolltotop.init()

</script>

3. 按保存就OK。

蓝色代码：图片的网址
红色代码：图片的宽度
粉色代码：图片的高度

Tips：图片的宽度 + 高度一定要根据你的图片来改，不然图片就不漂亮了哦。
