<SCRIPT>
secs = 60; // Number of secs to delay -CHINA-studio
wait = secs * 100;
document.forms.register.Submit.disabled =true;
for(i=1;i<=(wait/100);i++) {
window.setTimeout("doUpdate(" + i + ")", i * 100);
}
window.setTimeout("Timer()", wait);

function doUpdate(num) {
if(num == (wait/100)) {
document.forms.register.Submit.value = " 同意注册 ";
} else {
wut = (wait/100)-num;
document.forms.register.Submit.value = " 同意前请先阅读 (" + wut + ")";
}
}

function Timer() {
document.forms.register.Submit.disabled =false;
}
