1.将下面的代码复制到<head>内
<script> /* Thumbnail image viewer- ?Dynamic Drive () For full source code, usage terms, and 100's more DHTML scripts, visit */ function enlarge(which,e){ //Render image code for IE 4+ if (document.all){ if (showimage.style.visibility=="hidden"){ showimage.style.left=document.body.scrollLeft+event.clientX showimage.style.top=document.body.scrollTop+event.clientY showimage.innerHTML='<img src="'https://www.jb51.net/+which+'">' showimage.style.visibility="visible" } else showimage.style.visibility="hidden" return false } //Render image code for NS 4 else if (document.layers){ if (document.showimage.visibility=="hide"){ document.showimage.document.write('<a href="#"><img src="'https://www.jb51.net/+which+'" border=0></a>') document.showimage.document.close() document.showimage.left=e.x document.showimage.top=e.y document.showimage.visibility="show" } else document.showimage.visibility="hide" return false } //if NOT IE 4+ or NS 4, simply display image in full browser window else return true } </script> <script language="JavaScript1.2"> //By Dynamicdrive.com //drag drop function for NS 4//// ///////////////////////////////// var nsx var nsy var nstemp function drag_dropns(name){ temp=eval(name) temp.captureEvents(Event.MOUSEDOWN | Event.MOUSEUP) temp.onmousedown=gons temp.onmousemove=dragns temp.onmouseup=stopns } function gons(e){ temp.captureEvents(Event.MOUSEMOVE) nsx=e.x nsy=e.y } function dragns(e){ temp.moveBy(e.x-nsx,e.y-nsy) return false } function stopns(){ temp.releaseEvents(Event.MOUSEMOVE) } //drag drop function for IE 4+//// ///////////////////////////////// var dragapproved=false function drag_dropie(){ if (dragapproved==true){ document.all.showimage.style.pixelLeft=tempx+event.clientX-iex document.all.showimage.style.pixelTop=tempy+event.clientY-iey return false } } function initializedragie(){ if (event.srcElement.parentElement.id=="showimage"){ iex=event.clientX iey=event.clientY tempx=showimage.style.pixelLeft tempy=showimage.style.pixelTop dragapproved=true document.onmousemove=drag_dropie } } if (document.all){ document.onmousedown=initializedragie document.onmouseup=new Function("dragapproved=false") } </script>
2.在<body>中加入
复制代码 代码如下:
<div></div>
3.在连接图片的地方这样写
复制代码 代码如下:
<a href="https://www.jb51.net/photo1.jpg"><img src="https://www.jb51.net/thumbnail.gif"></a>
