CSS实现鼠标移上去显示大图效果

--------------------------------------------------css部分-----------------------------------

#demo{overflow:hidden;;text-align:center;padding:10px;}
#demo img{border:none;border:5px solid #f4f4f4}
#enlarge_images{position:absolute;display:none;z-index:1;border:5px solid #f4f4f4}

--------------------------------------------------页面部分-----------------------------------

<div id="demo" class="k_bg_demo">

<img src="images/batno/02.jpg" width="200" height="150" > </div><div id="enlarge_images">

</div>

--------------------------------------------------JS部分-----------------------------------

var demo = document.getElementById("demo");
var gg = demo.getElementsByTagName("img");
var ei = document.getElementById("enlarge_images");
for(i=0; i<gg.length; i++){
var ts = gg[i];
ts.onmousemove = function(event){
event = event || window.event;
ei.style.display = "block";
ei.innerHTML = '<img src="' + this.src + '" />';
ei.style.top = document.body.scrollTop + event.clientY + 10 + "px";
ei.style.left = document.body.scrollLeft + event.clientX + 10 + "px";
}
ts.onmouseout = function(){
ei.innerHTML = "";
ei.style.display = "none";
}
ts.onclick = function(){
window.open( this.src );
}
}

注：如果页面中有多张图片要应用此效果，可以此js代码外再加一层循环

如页面部分有两张图片要应用此效果

<div id="demo0" class="k_bg_demo">

<img src="images/batno/02.jpg" width="200" height="150" > </div><div id="enlarge_images">

</div>

<div id="demo1" class="k_bg_demo">

<img src="images/batno/02.jpg" width="200" height="150" > </div><div id="enlarge_images">

</div>

js部分改为：
for(var j=0;j<8;j++){

上js部分的代码

var demo = document.getElementById("demo"+j);

}

<style>#demo{overflow:hidden;;text-align:center;padding:10px;}#demo img{border:none;border:5px solid #f4f4f4}#enlarge_images{position:absolute;display:none;z-index:1;border:5px solid #f4f4f4}</style><p id="demo"><img src="http://www.wfuyu.com/uploads/allimg/091009/1-0910092136460-L.jpg" width="200" height="150" ><img src="http://www.wfuyu.com/uploads/userup/0903/231052306309.jpg" width="200" height="150" ><img src="http://www.wfuyu.com/uploads/allimg/091011/1_091011093642_1.jpg" width="200" height="150" ></p><div id="enlarge_images"></div><script>var demo = document.getElementById("demo");var gg = demo.getElementsByTagName("img");var ei = document.getElementById("enlarge_images");for(i=0; i<gg.length; i++){var ts = gg[i];ts.onmousemove = function(event){event = event || window.event;ei.style.display = "block";ei.innerHTML = '<img src="' + this.src + '" />';ei.style.top = document.body.scrollTop + event.clientY + 10 + "px";ei.style.left = document.body.scrollLeft + event.clientX + 10 + "px";}ts.onmouseout = function(){ei.innerHTML = "";ei.style.display = "none";}ts.onclick = function(){window.open( this.src );}}</script><br /><center>如不能显示效果，请按Ctrl+F5刷新本页，更多网页代码：<a href='http://www.wfuyu.com/' target='_blank'>http://www.wfuyu.com/</a></center>
提示：可修改后代码再运行!
