本文實例為大家分享了4種js計算系統(tǒng)當(dāng)前日期是星期幾的方法,供大家參考,具體內(nèi)容如下
方法一:
// 計算系統(tǒng)當(dāng)前是星期幾
var str = "今天是星期" + "日一二三四五六".charat(new date().getday());
方法二:
var a = new array("日", "一", "二", "三", "四", "五", "六");
var week = new date().getday();
var str = "今天是星期"+ a[week];
alert(str);
方法三:
var str = "今天是星期";
var week = new date().getday();
switch (week) {
case 0 :
str1 += "日";
break;
case 1 :
str1 += "一";
break;
case 2 :
str1 += "二";
break;
case 3 :
str1 += "三";
break;
case 4 :
str1 += "四";
break;
case 5 :
str1 += "五";
break;
case 6 :
str1 += "六";
break;
}
alert(str);
方法四:
var str = "";
var week = new date().getday();
if (week == 0) {
str = "今天是星期日";
} else if (week == 1) {
str = "今天是星期一";
} else if (week == 2) {
str = "今天是星期二";
} else if (week == 3) {
str = "今天是星期三";
} else if (week == 4) {
str = "今天是星期四";
} else if (week == 5) {
str = "今天是星期五";
} else if (week == 6) {
str = "今天是星期六";
}
alert(str);
