[求助]注册是按钮有个倒计时的功能
像好多网站注册的时候阅读服务条款那个同意按钮不是有个倒计时么。。JS代码如下：
<script language="JavaScript">
var secs = 9;
var wait = secs * 1000;
document.bbrules.rulesubmit.value = "同 意(" + secs + ")";
document.bbrules.rulesubmit.disabled = true;
for(i = 1; i <= secs; i++) {
window.setTimeout("update(" + i + ")", i * 1000);
}
window.setTimeout("timer()", wait);
function update(num, value) {
if(num == (wait/1000)) {
document.bbrules.rulesubmit.value = "同 意";
} else {
printnr = (wait / 1000)-num;
document.bbrules.rulesubmit.value = "同 意(" + printnr + ")";
}
}
function timer() {
document.bbrules.rulesubmit.disabled = false;
document.bbrules.rulesubmit.value = "同 意";
}
</script>
其中rulesubmit是同意按钮的名字 那document.bbrules.是指什么呢？ 如果我自已写这里该怎么改？
看了好多网站都是这样的 这里用的都是“document.bbrules.” 实在想不明白
