这篇文章主要介绍了通过js实现的,当鼠标移到图片上变大显示而不是放大镜效果,需要的朋友可以参考下
ToopTip.js:
复制代码 代码如下:

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;
}
}
/*
[html]
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:
[code]
<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
复制代码 代码如下:

.trans_msg
{
filter:alpha(opacity=100,enabled=1) revealTrans(duration=.2,transition=1) blendtrans(duration=.2);
}
*/
//--初始化变量--
var rT=true;//允许图像过渡
var bT=true;//允许图像淡入淡出
var tw=150;//提示框宽度
var endaction=false;//结束动画
var ns4 = document.layers;
var ns6 = document.getElementById && !document.all;
var ie4 = document.all;
offsetX = 10;
offsetY = 20;
var toolTipSTYLE="";
function initToolTips()
{
tempDiv = document.createElement("div");
tempDiv.id = "toolTipLayer";
tempDiv.style.position = "absolute";
tempDiv.style.display = "none";
document.body.appendChild(tempDiv);
if(ns4||ns6||ie4)
{
if(ns4) toolTipSTYLE = document.toolTipLayer;
else if(ns6) toolTipSTYLE = document.getElementById("toolTipLayer").style;
else if(ie4) toolTipSTYLE = document.all.toolTipLayer.style;
if(ns4) document.captureEvents(Event.MOUSEMOVE);
else
{
toolTipSTYLE.visibility = "visible";
toolTipSTYLE.display = "none";
}
document.onmousemove = moveToMouseLoc;
}
}
function toolTip(msg, fg, bg)
{
try {
if(toolTip.arguments.length < 1) // hide
{
if(ns4)
{
toolTipSTYLE.visibility = "hidden";
}
else
{
//--图象过渡,淡出处理--
if (!endaction) {toolTipSTYLE.display = "none";}
if (rT) document.all("msg1").filters[1].Apply();
if (bT) document.all("msg1").filters[2].Apply();
document.all("msg1").filters[0].opacity=0;
if (rT) document.all("msg1").filters[1].Play();
if (bT) document.all("msg1").filters[2].Play();
if (rT){
if (document.all("msg1").filters[1].status==1 || document.all("msg1").filters[1].status==0){
toolTipSTYLE.display = "none";}
}
if (bT){
if (document.all("msg1").filters[2].status==1 || document.all("msg1").filters[2].status==0){
toolTipSTYLE.display = "none";}
}
if (!rT && !bT) toolTipSTYLE.display = "none";
//----------------------
}
}
else // show
{
if(!fg) fg = "#777777";
if(!bg) bg = "#eeeeee";
var content =
'<table id="msg1" name="msg1" border="0" cellspacing="0" cellpadding="1" bgcolor="' + fg + '" class="trans_msg"><td>' +
'<table border="1" cellspacing="2" cellpadding="3" bgcolor="' + bg +
'"><td><font face="Arial" color="' + fg +
'" size="-2">' + msg +
'</font></td></table></td></table>';

if(ns4)
{
toolTipSTYLE.document.write(content);
toolTipSTYLE.document.close();
toolTipSTYLE.visibility = "visible";
}
if(ns6)
{
document.getElementById("toolTipLayer").innerHTML = content;
toolTipSTYLE.display='block'
}
if(ie4)
{
document.all("toolTipLayer").innerHTML=content;
toolTipSTYLE.display='block'
//--图象过渡,淡入处理--
var cssopaction=document.all("msg1").filters[0].opacity
document.all("msg1").filters[0].opacity=0;
if (rT) document.all("msg1").filters[1].Apply();
if (bT) document.all("msg1").filters[2].Apply();
document.all("msg1").filters[0].opacity=cssopaction;
if (rT) document.all("msg1").filters[1].Play();
if (bT) document.all("msg1").filters[2].Play();
//----------------------
}
}
} catch(e) {}
}
function moveToMouseLoc(e)
{
var scrollTop = getScrollTop();
var scrollLeft = getScrollLeft();
if(ns4||ns6)
{
x = e.pageX + scrollLeft;
y = e.pageY - scrollTop;
}
else
{
x = event.clientX + scrollLeft;
y = event.clientY;
}

if (x-scrollLeft > getViewportWidth() / 2) {
x = x - document.getElementById("toolTipLayer").offsetWidth - 2 * offsetX;
}

if ((y+document.getElementById("toolTipLayer").offsetHeight+offsetY)>getViewportHeight()) {
y = getViewportHeight()-document.getElementById("toolTipLayer").offsetHeight-offsetY;
}
toolTipSTYLE.left = (x + offsetX)+'px';
toolTipSTYLE.top = (y + offsetY + scrollTop)+'px';
return true;
}
initToolTips();

主页面:
引入index.css
复制代码 代码如下:

<link href="css/index.css" rel="stylesheet" type="text/css" />
<body style="text-align:center">

<div class="latestWeb">
<ul>

<li class="">
<div style="width:128px; height:126px"><a href="http://www.lanrentuku.com/" target="_blank"><img src='images/2009511956153474660_small.jpg' onMouseOver="toolTip('<img src=images/2009511956153474660.jpg>')" onMouseOut="toolTip()"></a></div>
</li>

<li class="">
<div style="width:128px; height:126px"><a href="http://www.lanrentuku.com/" target="_blank"><img src='images/2009551813457815940_small.jpg' onMouseOver="toolTip('<img src=images/2009551813457815940.jpg>')" onMouseOut="toolTip()"></a></div>
</li>

</ul>
</div>

引入ToopTip.js
复制代码 代码如下:

<script language="javascript" src="js/ToolTip.js"></script>

index.css:
复制代码 代码如下:

/*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;}

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);}
