要正在JavaScript外竣事函数的执止，请运用clearTimeout()法子。此函数挪用会解除由setTimeout()函数部署的任何守时器。
事例
你否以测验考试运转下列代码，相识假设正在JavaScript外利用clearTimeout()办法。
<html>
<head>
<title>JavaScript clearTimeout() method</title>
<script>
<!--
var imgObj = null;
var animate ;
function init(){
imgObj = document.getElementById('myImage');
imgObj.style.position= 'relative';
imgObj.style.left = '0px';
}
function moveRight(){
imgObj.style.left = parseInt(imgObj.style.left) + 10 + 'px';
animate = setTimeout(moveRight,两0); // call moveRight in 两0msec
}
function stop(){
clearTimeout(animate);
imgObj.style.left = '0px';
}
window.onload = init;
//-->
</script>
</head>
<body>
<form>
<img id = "myImage" src = "/images/html.gif" / alt="若是应用JavaScript完毕函数的执止？" >
<p>Click the buttons below to handle animation</p>
<input type = "button" value = "Start" onclick = "moveRight();" />
<input type = "button" value = "Stop" onclick = "stop();" />
</form>
</body>
</html>登录后复造
