请看下面代码,这是我在网上看到的图片自由移动的代码：
<body OnLoad="www_helpor_net()" OnResize="www_helpor_net()">
<div id="helpor_net" style="position:absolute; visibility:visible; left:0px; top:0px; z-index:-1">
<img src="http://code.helpor.net/picture/swimming.gif" border="0">
</div>
<SCRIPT LANGUAGE="JavaScript">
<!--
var isNS = ((navigator.appName == "Netscape") && (parseInt(navigator.appVersion) >= 4));
var _all = '';
var _style = '';
var wwidth, wheight;
var ydir = '++';
var xdir = '++';
var id1, id2, id3;
var x = 1;
var y = 1;
var x1, y1;
if(!isNS) {
_all='all.';
_style='.style';
}
function www_helpor_net() {
clearTimeout(id
<body OnLoad="www_helpor_net()" OnResize="www_helpor_net()">
<div id="helpor_net" style="position:absolute; visibility:visible; left:0px; top:0px; z-index:-1">
<img src="http://code.helpor.net/picture/swimming.gif" border="0">
</div>
<SCRIPT LANGUAGE="JavaScript">
<!--
var isNS = ((navigator.appName == "Netscape") && (parseInt(navigator.appVersion) >= 4));
var _all = '';
var _style = '';
var wwidth, wheight;
var ydir = '++';
var xdir = '++';
var id1, id2, id3;
var x = 1;
var y = 1;
var x1, y1;
if(!isNS) {
_all='all.';
_style='.style';
}
function www_helpor_net() {
clearTimeout(id
helpor_net.pixelLeft = x+document.body.scrollLeft;
helpor_net.pixelTop = y+document.body.scrollTop;
}
if (isNS) {
if (helpor_net.top <= 5+pageYOffset) ydir = '++';
if (helpor_net.top >= wheight+pageYOffset) ydir = '--';
if (helpor_net.left >= wwidth+pageXOffset) xdir = '--';
if (helpor_net.left <= 5+pageXOffset) xdir = '++';
} else {
if (helpor_net.pixelTop <= 5+document.body.scrollTop) ydir = '++';
if (helpor_net.pixelTop >= wheight+document.body.scrollTop) ydir = '--';
if (helpor_net.pixelLeft >= wwidth+document.body.scrollLeft) xdir = '--';
if (helpor_net.pixelLeft <= 5+document.body.scrollLeft) xdir = '++';
在这里面 把Top和Left 改改
