javascript 自帶有個對象(構造函數)，Date().下面是代碼：
回答一：
var now = new Date();
var nowTime = now.toLocaleString();
var date = nowTime.substring(0,10);//截取日期
var time = nowTime.substring(10,20); //截取時間
var week = now.getDay(); //星期
var hour = now.getHours(); //小時
回答二：
var date = new Date();
var year = date.getFullYear();
var month = date.getMonth()+1;
var day = date.getDate();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
alert(year+‘年‘+month+‘月‘+day+‘日 ‘+hour‘:‘+minute+‘:‘+second)
回答三：
function showTime() {
var now = new Date();
var nowTime = now.toLocaleString(); var date = nowTime.substring(0,10);//截取日期
var time = nowTime.substring(10,20); //截取時間
var week = now.getDay(); //星期
var hour = now.getHours(); //小時
//判斷星期幾
var weeks = ["日","一","二","三","四","五","六"];
var getWeek = "星期" + weeks[week];
var sc;
//判斷是AM or PM
if(hour >= 0 && hour < 5){ sc = ‘淩晨‘;
}
else if(hour > 5 && hour <= 7){
sc = ‘早上‘;
}
else if(hour > 7 && hour <= 11){
sc = ‘上午‘;
}
else if(hour > 11 && hour <= 13){
sc = ‘中午‘;
}
else if(hour> 13 && hour <= 18){
sc = ‘下午‘;
}
else if(hour > 18 && hour <= 23){
sc = ‘晚上‘;
}
document.getElementById(‘time‘).innerHTML ="當前時間：" + date+" " + getWeek +" "+" "+sc+" "+time;
setTimeout(‘showTime()‘,1000);
}
</script>
調用方法:
<body onload="showTime()">
<div id="time"></div>
</body>
