本文实例讲述了JS控制按钮10秒钟后可用的方法。分享给大家供大家参考，具体如下：

<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>

希望本文所述对大家JavaScript程序设计有所帮助。
