将某个按钮禁用5秒钟
我想在页面加载时，前5秒将btnTJ按钮禁用，请问我怎么写代码 --------------------编程问答-------------------- 以前以为高手给出的答案是利用时间差 两个时间相减 --------------------编程问答-------------------- 取出系统的当前时间的秒
然后和加5进行比较 --------------------编程问答-------------------- 给代码看看阿 --------------------编程问答-------------------- 使用js
<script type="text/javascript">
<!--
var secs = 9;
var wait = secs * 1000;
var btnId = "BtnRegStep1";
document.getElementById(btnId).value = "我同意 [" + secs + "]";
document.getElementById(btnId).disabled = true;
for(i = 1; i <= secs; i++)
{
window.setTimeout("Update(" + i + ")", i * 1000);
}
window.setTimeout("Timer()", wait);
function Update(num)
{
if(num != secs)
{
printnr = (wait / 1000) - num;
document.getElementById(btnId).value = "我同意 [" + printnr + "]";

贴子烂，LZ也不结，你什么人啊？BS
贴子烂--帖子那里烂了?你天生就天才啊!你学1+1的时候不知道你是不是傻B啊!你说你傻B吧也不要紧,自己再家里傻,别出来傻,出来傻就是你的不对了.
LZ也不结--结不结管你易做图事啊?有空回家管管你老婆,看看是不是在偷男人,不该你管的事少他妈管,CSDN是你家的啊,你这种人就是易做图,以后少他妈的易做图,你要是在我跟前的话,我非扇你个B.
你什么人啊?---不管什么人,都轮不到你发表意见,等你老婆偷男人的时候,你就和你老婆说"你什么人啊".

--------------------编程问答-------------------- 按钮先直接设成禁用
在页面加载函数里 settimeout(A,5000)
A函数里把按钮禁用取消了 --------------------编程问答-------------------- 方法真的很多：
1、利用JS内的SetTimeOut();
2、利用获取当前时间的秒+5后，然后不断地和当前时间的秒进行比较，如果相等了就解除禁用；
3、利用Timer控件吧。 --------------------编程问答-------------------- <html>
