以下是网页中图片超过指定大小自动缩放，并且可以点击看大图的代码

[CODE=javascript] //改变图片大小 function resizeImg() { var contentwidth=565;//设置图片最大宽度 var imageAll=document.getElementById("con").getElementsByTagName("img");//con为图片所在层的ID var turewidth,tureheight; if (imageAll !=null) { for (i=0; iimageAll[i].width) { if(imageAll[i].height==tureheight) { imageAll[i].style.height=imageAll[i].height/turewidth*imageAll[i].width+"px"; } imageAll[i].onclick=function(){window.open(this.src)}; imageAll[i].style.cursor="pointer"; imageAll[i].title="点击查看原始尺寸："+turewidth+"*"+tureheight+"px"; } else { imageAll[i].style.width=turewidth+"px"; } } } } if (window.addEventListener) window.addEventListener("load", resizeImg, false); else if (window.attachEvent) window.attachEvent("onload", resizeImg); else window.onload=resizeImg [/CODE]
