?5,图片的淡入淡出
<html xmlns="http://www.w3.org/1999/xhtml" ><head><title>标题页</title></head><body onLoad="fade()"><img src="logo1.gif" name="img" border=0alt="js 操绘制片的各种效果 第一篇" style="filter:alpha(opacity=0)"> <script language="JavaScript">var bOpa = 1;var c = true;function fade(){ if(document.all); if(c == true) { bOpa++; } if(bOpa==100) { //透明度到100时，开始减少 bOpa--; c = false } if(bOpa==10) { //透明度到10时，控制透明度增减的参数变为true bOpa++; c = true; } if(c == false) { //控制透明度是加还是减 bOpa--; } img.filters.alpha.opacity=0 + bOpa; //改变图像的透明度 setTimeout("fade()",50); //定时执行fade方法}</script></body></html>?
6，图片的渐隐播放效果
<HTML><HEAD><TITLE>图像的渐隐播放效果</TITLE><script language=javaScript>var strngth=1var index_image=0var imageSrc = new Array()imageSrc[0] ="logo1.gif"imageSrc[1] ="logo2.gif"imageSrc[2] ="logo1.gif"function showimage() //显示图像{ if(document.all) { //创建一个带滤镜样式的img图像-注意显示的图像并不固定 if (strngth <=110) { imagediv.innerHTML="<img style='filter:alpha(opacity="+strngth+")' src="+imageSrc[index_image]+" border=0>"; strngth=strngth+10 var timer=setTimeout("showimage()",100) //每隔100豪秒就显示图像 } else { clearTimeout(timer) var timer=setTimeout("hideimage()",1000) //每隔1000豪秒就隐藏图像 } } //是Netscape浏览器时的特效实现方法 if(document.layers) { clearTimeout(timer) document.imagediv.document.write("<img src="+imageSrc[index_image]+" border=0>") document.close() index_image++ if (index_image >= imageSrc.length) {index_image=0} var timer=setTimeout("showimage()",2000) } }function hideimage() //隐藏图像{ if (strngth >=-10) { //设置图像逐渐消隐的滤镜效果-注意图像并不固定 imagediv.innerHTML="<img style='filter:alpha(opacity="+strngth+")' src="+imageSrc[index_image]+" border=0>"; strngth=strngth-10 var timer=setTimeout("hideimage()",100) //每隔100豪秒就隐藏图像 } else { clearTimeout(timer) index_image++ if (index_image >= imageSrc.length) {index_image=0} strngth=1 var timer=setTimeout("showimage()",500) //每隔500豪秒就显示图像 }}</script></HEAD><body onLoad="showimage()"><div id="imagediv" style="position:absolute;"></div></body></HTML>?7，晃动的图片
<html xmlns="http://www.w3.org/1999/xhtml" ><head><title>晃动的图片</title><script language="JavaScript">step = 0;obj = new Image(); //创建图片对象function anim(xp,xk,smer) //smer 代表晃动方向{ obj.style.left = x; x += step*smer; if (x>=(xk+xp)/2) { if (smer == 1) step--; //往左移动 else step++; } else { if (smer == 1) step++; //往右移动 else step--; } if (x >= xk) { //如果已经到右边界，则反向晃动 x = xk; smer = -1; } if (x <= xp) { //如果一定到左边界，则反向晃动 x = xp; smer = 1; } setTimeout('anim('+xp+','+xk+','+smer+')', 40); //设置定时器，实现不断晃动效果}function moveLR(objID,movingarea_width,c){ if (navigator.appName=="Netscape") window_width = window.innerWidth; else window_width = document.body.offsetWidth; //获取窗体的宽度 obj = document.images[objID]; image_width = obj.width; //获取图像的宽度 x1 = obj.style.left; //获取图像的X坐标 x = Number(x1.substring(0,x1.length-2)); //去掉后面的像素标记“px” if (c == 0) { if (movingarea_width == 0) { //没有设置移动区域的情况 right_margin = window_width - image_width; anim(x,right_margin,1); //开始晃动图片} else { right_margin = x + movingarea_width - image_width; if (movingarea_width < x + image_width) window.alert("No space for moving!"); else anim(x,right_margin,1);} } else { if (movingarea_width == 0) //没有设置移动区域的情况 right_margin = window_width - image_width; else { x = Math.round((window_width-movingarea_width)/2); right_margin = Math.round((window_width+movingarea_width)/2)-image_width;//获取可以移动的空间 }anim(x,right_margin,1); } }</script><img src="http://www.baidu.com/img/logo.gif" name="img1" style='position: absolute; top: 50px; left: 213px;' border=0 id="myImg"> <script language="JavaScript"> setTimeout("moveLR('myImg',400,1)",10);</script></head><body></body></html>?8，文本域中可编辑的图片
<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>New Page</title></head><body><textarea id=t1 cols=30 rows=3 ></textarea><img src="http://img.baidu.com/hi/logo-pb.gif" id=img1> <script language="javascript">t1.appendChild(img1) //动态添加图片到文本区域img1.UNSELECTABLE=true; //取消图片的选中操作</script> </body></html>

9，禁止图像复制
<html xmlns="http://www.w3.org/1999/xhtml" ><head> <title>标题页</title> <script language="javascript"> function noCopy(control) {alert("版权所有，禁止复制！");return false; } function check() {if(document.images) //遍历页面中的图像 for(i=0;i<document.images.length;i++)document.images[i].onmousedown = noCopy; } </script> </head><body onload="check()"><img src='' width=70 height=50 border=1 alt='我的图片'><div> </div> </body></html>?
