输出今天是星期几

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"; }

或者

var str1 = "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;}

或者

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];

或者

var str = "今天是星期" + "日一二三四五六".charAt(new Date().getDay());

只需要一句话就可以了。
