關於JS的時間控制
<script>
BOM //Bowers Object Model 瀏覽器物件模型
setTimeout()
// 順延強制一次
setInterval()
// 間隔執行
var a = 300;
window.setTimeout(‘abc(a)‘,3000);
// 自訂函數賦值
function abc(i)
{
alert(i);
}
//setInterval(‘alert(123)‘,2000);
var dh = document.getElementById("dh");
//alert(dh.offsetLeft);
function move() {
dh.style.marginLeft = dh.offsetLeft + 1 + ‘px‘;
}
var x = window.setInterval(‘move()‘, 20);
var y = window.setInterval(‘move()‘, 500);
function clear() {
window.clearInterval(x);
}
//清除間隔執行
window.setTimeout("clear()",2500);
// 要執行的代碼；間隔時間
window.setInterval(‘alert(123)‘,1000);
</script>
利用時間控制實現鐘錶的操作
<style>
*{
margin: 150px auto;
width:500px;
height:500px;
}
</style>
<body>
<div>
<span id="h"></span>
<span id="m"></span>
<span id="s"></span>
</div>
<script type="text/javascript">
window.setInterval("time()",1000);
自訂時間函數
function time(){
日期時間函數調用
var time = new Date();
document.getElementById("h").innerText = time.getHours() +‘:‘;
document.getElementById("m").innerText = time.getMinutes() +‘:‘;
document.getElementById("s").innerText = time.getSeconds();
}
</script>
</body>
