本文實例講述了JS控制按鈕10秒鐘后可用的方法。分享給大家供大家參考，具體如下：
<script language="javascript">function start(){ document.getElementById("Button1").disabled = true; document.getElementById("Button1").value = 10; window.setTimeout("tick()",1000);}function tick(){ var time = new Number(document.getElementById("Button1").value); if(time>0) { document.getElementById("Button1").value = time-1; window.setTimeout("tick()",1000); } else { document.getElementById("Button1").disabled = false; document.getElementById("Button1").value = "保存"; }}</script><form><INPUT TYPE="button" NAME="Button1" id="Button1"></form><script language=javascript> start();</script> 希望本文所述對大家JavaScript程序設計有所幫助。
