主题名称：图像特殊效果<br>
<br>
特效名称：左右移动的图片<br>
<br> [修改图片名称即可][共2步]
<br>1、将以下代码加入到HEML的<head></head>之间：
<script LANGUAGE="JavaScript"><!--
step = 0;
obj = new Image();
function anim(xp,xk,smer) //smer = direction
{
obj.style.left = x;
x += step*smer;
if (x>=(xk+xp)/2) {
if (smer == 1) step--;
else step++;
}
else {
if (smer == 1) step++;
else step--;
}
if (x >= xk) {
x = xk;
smer = -1;
}
if (x <= xp) {
x = xp;
smer = 1;
}
// if (smer > 2) smer = 3;
setTimeout('anim('+xp+','+xk+','+smer+')', 50);
}
function moveLR(objID,movingarea_width,c)
{
if (navigator.appName=="Netscape") window_width = window.innerWidth;
else window_width = document.body.offsetWidth;
obj = document.images[objID];
image_width = obj.width;
x1 = obj.style.left;
x = Number(x1.substring(0,x1.length-2)); // 30px -> 30
if (c == 0) {
if (movingarea_width == 0) {
right_margin = window_width - image_width;
anim(x,right_margin,1);
}
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) 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;
}
anim(x,right_margin,1);
}
}
//--></script>
<br>2、将以下代码加入到HEML的<body></body>之间：
<img src="1548.jpg" name="picture"
style="position: absolute; top: 70px; left: 30px;" BORDER="0" WIDTH="140" HEIGHT="40">
<script LANGUAGE="JavaScript"><!--
setTimeout("moveLR('picture',300,1)",10);
//--></script>
<html></html>
<html></html>
看这个对你有不有帮助!
