一种把人吓一跳的感觉。实现方法是，把下面的JavaScript代码加入到< body与< /body之间：

< script language="JavaScript"

function surfto(form) {

var myindex=form.select1.selectedIndex

if (form.select1.options[myindex].value != null) {

parent.main.location.href=form.select1.options[myindex].value;

} }

< /script //这段JS代码意为当前页面的浏览器地震//

< script language="JavaScript1.2"

function shake(n) {

if (window.top.moveBy) {

for (i = 10; i 0; i--) {

for (j = n; j 0; j--) {

window.top.moveBy(0,i);

window.top.moveBy(i,0);

window.top.moveBy(0,-i);

window.top.moveBy(-i,0);

} } }

alert("呀~~地震啦！没~~吓坏吧？^_*"); //这里设定地震后弹出的嬉戏性文字(据需随意)//

}

< /script

< script language="JavaScript"
