文章系统下的图片展示效果,鼠标经过小图时出现大图。研究了一下发现很好用,拿出来分享一下。
效果展示:
---------------------------------------------------------------------------------------
首先要用到的SQL循环:
<li class="">
<div style="width:128px; height:126px"><a href="连接地址" target="_blank"><img src='小图地址' onMouseOver="toolTip('<img src=大图地址>')" onMouseOut="toolTip()"></a></div>
</li>
这里用到一个小图地址我在文章系统里加了一个字段:"ks_smallphoto"
新建SQL名称为:
{SQL_实验中心小图 大图()}
具体SQL:
select ID,PhotoUrl,KS_smallphoto from KS_Article where tid='20084931548132' order by id desc
循 环 体
<li class="">
<div style="width:128px; height:126px"><a href="{$Field(ID,GetInfoUrl,1,1)}" target="_blank"><img src='{$Field(KS_smallphoto,Text,0,...,0,)}' onMouseOver="toolTip('<img src={$Field(PhotoUrl,Text,0,...,0,)}>')" onMouseOut="toolTip()"></a></div>
</li>
----------------------------下面为JS代码-----------------------------------
function getViewportHeight() {
if (window.innerHeight!=window.undefined) return window.innerHeight;
if (document.compatMode=='CSS1Compat') return document.documentElement.clientHeight;
if (document.body) return document.body.clientHeight;
return window.undefined;
}
function getViewportWidth() {
if (window.innerWidth!=window.undefined) return window.innerWidth;
if (document.compatMode=='CSS1Compat') return document.documentElement.clientWidth;
if (document.body) return document.body.clientWidth;
return window.undefined;
}
/**
* Gets the real scroll top
*/
function getScrollTop() {
if (self.pageYOffset) // all except Explorer
{
return self.pageYOffset;
}
else if (document.documentElement && document.documentElement.scrollTop)
// Explorer 6 Strict
{
return document.documentElement.scrollTop;
}
else if (document.body) // all other Explorers
{
return document.body.scrollTop;
}
}
function getScrollLeft() {
if (self.pageXOffset) // all except Explorer
{
return self.pageXOffset;
}
else if (document.documentElement && document.documentElement.scrollLeft)
// Explorer 6 Strict
{
return document.documentElement.scrollLeft;
}
else if (document.body) // all other Explorers
{
return document.body.scrollLeft;
}
}
/*
渐变的弹出图片
使用方法:
将ToolTip.js包含在网页body的结束标签后
调用方法:
<a href="pages.jpg" target='_blank' onMouseOver="toolTip('<img src=http://zhouzh:90/templet/T_yestem_channel/pages_small.jpg>')" onMouseOut="toolTip()"><img src='pages_small.jpg' border=0 width=30 height=20 align="absmiddle" title="点击看大图"></a>
必须CSS样式
.trans_msg
{
filter:alpha(opacity=100,enabled=1) revealTrans(duration=.2,transition=1) blendtrans(duration=.2);
}

ps:把这段JS保存为“ToolTip.js”放在BODY结束的地方调用就行了。
--------------------------下面为用到的CSS样式可放在头部在可调用--------------------------------
/*首页*/
html { overflow:-moz-scrollbars-vertical; } /*Always show Firefox scrollbar*/
body{ font:12px/22px "宋体"; word-break:break-all; text-align:left; background:#C0C0C0; color:#4E4E4E;}
ul,li{ list-style:none;}
a{ color:#333; text-decoration:none;}
a:hover{ color:#ff722d; text-decoration:none;}
img{ border:0;}
a img,a:hover img{ border:0;}
.latestWeb{ width:980px; margin:10px auto 0;}
.latestWeb ul{ overflow:hidden; _height:1%;}
.latestWeb li{ float:left; border:1px solid #EBEAEA; width:150px; padding:10px; margin:14px 14px 0 0; }
.trans_msg{ filter:alpha(opacity=100,enabled=1) revealTrans(duration=.2,transition=1) blendtrans(duration=.2);}
div.bodycontent{font-family:Arial, Helvetica, sans-serif;padding:0 10px 10px 13px;color:#555;line-height:22px;text-align:justify;text-justify:inter-ideograph;}
div.bodycontent ul{margin-left:0px}
-----------------------------------------------------------------------------------
我是这样调用的
<body>
<div class="latestWeb">
<ul>
{SQL_实验中心小图 大图()}
</ul>
</div>
</body>
<script language="javascript" src="/js/ToolTip.js"></script>
-----------------------------------------------------------------------------------
ps:其实这个效果也很简单的,官方ESHOP上出带有这个效果。小弟不才,如有足之处还请见谅。
