<div id= "soccer " style= "position:absolute;left:150;top:54;width:120;height:42 ">
<span id= "firstNum " style= "font-size:30pt "> 0 </span>

<div>
<input type= "button " value= "开始 " onclick= "start1() "> <input type= "button " value= "停止 " onclick= "stop() ">
</div>
<script language= "javascript ">
var msecs = 10;
var t;
function start1(){
var t = setTimeout( "blink() ",msecs);
}
function blink(){
var firstNum = document.getElementById( "firstNum ");
firstNum.innerText = parseInt(Math.random() * 10);
secondNum.innerText = parseInt(Math.random() * 10);
thirdNum.innerText = parseInt(Math.random() * 10);
fourthNum.innerText = parseInt(Math.random() * 10);
t = setTimeout( "blink() ",msecs);
}
function stop(){
clearTimeout(t);
}
</script>
</body>
</html>
这个程序运行正常，但是有个小bug——
如果我点3次“开始”，那要点3次“停止”才能让它停下来
请问怎样修改程序，无论怎么点“开始”，点一次“停止”就能停下来？
