网站延时注册代码(JS)

下面的代码是用JS实现网站延时注册的功能,倒计时时不能注册,延时结束时方可进行注册

<FORM name=register method=post action=reg.asp?action=yes>
<input type="hidden" name="action" value="agree">
<INPUT class="auuo" type=submit value=" 同意注册 " name=Submit>
</FORM>
<SCRIPT>
 secs = 60; // 延时时间,这里设了60毫秒
 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;
}
</SCRIPT>

上面这段代码另存为html即可运行,此延时代码,在论坛注册与会员注非常常见。
