2006到2016的航天事业:html中的浮动框是怎样做的

来源：百度文库 编辑：杭州交通信息网 时间：2024/05/11 04:13:49
举例说明更好，谢谢拉

浮动图片吗?
在<body>和</body>中加入这段代码,

<div id="img" style="position:absolute;">
<a href="http://www.helpor.net" target="_blank">
<img src="http://code.helpor.net/picture/swimming.gif" border="0"></a>
</div>

<SCRIPT LANGUAGE="JavaScript">
<!--
var xPos = 20;
var yPos = document.body.clientHeight;
var step = 1;
var delay = 30;
var height = 0;
var Hoffset = 0;
var Woffset = 0;
var yon = 0;
var xon = 0;
var pause = true;
var interval;
img.style.top = yPos;
function changePos() {
width = document.body.clientWidth;
height = document.body.clientHeight;
Hoffset = img.offsetHeight;
Woffset = img.offsetWidth;
img.style.left = xPos + document.body.scrollLeft;
img.style.top = yPos + document.body.scrollTop;
if (yon) {
yPos = yPos + step;
}
else {
yPos = yPos - step;
}
if (yPos < 0) {
yon = 1;
yPos = 0;
}
if (yPos >= (height - Hoffset)) {
yon = 0;
yPos = (height - Hoffset);
}
if (xon) {
xPos = xPos + step;
}
else {
xPos = xPos - step;
}
if (xPos < 0) {
xon = 1;
xPos = 0;
}
if (xPos >= (width - Woffset)) {
xon = 0;
xPos = (width - Woffset);
}
}
function www_helpor_net() {
img.visibility = "visible";
interval = setInterval('changePos()', delay);
}
www_helpor_net();
//For more,visit:www.helpor.net
-->
</script>
再把src="http://code.helpor.net/picture/swimming.gif"一句中的http://....改成你自己电脑图片的地址或网络上其它图片的地址.

把下面的代码另存为 test.html 然后在IE中打开就可以了
