The code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id='box'></div>
<script>var oBox = document.getElementById("box");var maxLeft = utils.win('clientWidth')-oBox.offsetWidth;var step = 5;var timer = window.setInterval(function(){var curLeft = utils.css(oBox,"left");if(curLeft+step >= maxLeft){//边界判断utils.css(oBox,"left",maxLeft);
window.clearInterval(timer);return;
}
curLeft+=step;
utils.css(oBox,"left",curLeft);
},10)//问题:当总距离/我们设定的步长 = 不是一个整数。少走一步还差点距离到目标位置，多走一步会超出目标的位置//解决:在进行边界判断的时候加上步长来进行处理</script>
</body>
</html>
