javascript 自带有个对象(构造函数),Date().下面是代码:
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);
//截取时间
var
week = now.getDay();
//星期
var
hour = now.getHours();
//小时
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);
//截取时间
var
week = now.getDay();
//星期
var
hour = now.getHours();
//小时
//判断星期几
var
weeks = [
"日"
,
"一"
,
"二"
,
"三"
,
"四"
,
"五"
,
"六"
];
var
getWeek =
"星期"
+ weeks[week];
var
sc;
//判断是AM or PM
if
(hour >= 0 && hour < 5){
sc =
‘凌晨‘
;
}
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‘
;
}
setTimeout(
‘showTime()‘
,1000);
}
</script>
调用方法:
<body onload=
"showTime()"
>
<div id=
"time"
></div>
</body>
