Dreamweaver定制网页过渡功能:
首先用Dreamweaver打开页面，然后单击菜单中的Insert\Head\Meta（插入/文件头标签/Meta）.

　　在对话框中的Attribute选项的下拉列表中选HTTP-equivalent选项，在Value：中键入Page-Enter，表示进入网页时有网页过渡效果。在Content:中键入Revealtrans(Duration=6,Transition=2),Duration=6表示网页过渡效果的延续时间为6秒，Transition表示过渡效果方式，值为2时表示圆形收缩。
输入完后单击确定，存盘。这样当我们点击一个超链接进入这个页面时就可以看到效果了。另外还有二十多种效供你选择，只要将Transition的值改为相应的效果的代号即可，具体效果和设置如下表所示：

效果　Content 　Transitionv
盒状收缩 RevealTrans 0　
盒状展开　 RevealTrans 1
圆形收缩　 RevealTrans 2　
圆形展开 RevealTrans 3
向上擦除 RevealTrans 4
向下擦除 RevealTrans 5
向左擦除 RevealTrans 6
向右擦除 RevealTrans 7
垂直百页窗 RevealTrans 8
水平百页窗 RevealTrans 9
横向棋盘式 RevealTrans 10
纵向棋盘式 RevealTrans 11
溶解 RevealTrans 12
左右向中部收缩 RevealTrans 13
中部向左右展开 RevealTrans 14
上下向中部收缩 RevealTrans 15
中部向上下展开 RevealTrans 16
阶梯状向左下展开 RevealTrans 17
阶梯状向左上展开 RevealTrans 18
阶梯状向右下展开 RevealTrans 19
阶梯状向右上展开 RevealTrans 20
随机水平线 RevealTrans 21
随机垂直线 RevealTrans 22
随机 RevealTrans 23
加到文字中间，以显示倒计时。
<script>
var url = "html/index.html"; {'html/index.html'为转到页面}
var loctime = 9; {9=9秒}
timedown.innerhtml = loctime;

var gourl = setInterval("downtimes()",1000);
function downtimes(){
loctime--;
timedown.innerHTML= loctime;
if(loctime <= 0){
clearInterval(gourl);
window.location = url;
}
}
</script>

然后把
