todayDate = new Date(); |
当定义一个新的对象时,通常使用“new”操作符。在这里,就是创建了日期对象。 |
date = todayDate.getDate(); | getDate()是Date对象的一种方法,其功能是获得当前的日期。 |
month= todayDate.getMonth() + 1 ; |
getMonth()是Date对象的一种方法,其功能是获得当前的日期,由于月份是从0开始的,所以这里要“+1”。 |
year= todayDate.getYear() | getYear()是Date对象的一种方法,其功能是获得当前的年份。 |
if(navigator.appName == "Netscape") { document.write(1900+year); document.write("年"); document.write(month); document.write("月"); document.write(date); document.write("日"); document.write("<br> ") } |
如果浏览器是Netscape,输出今天是“year”+“年”+“month”+“月”+“date”+“日”,其中年要加1900。 |
if(navigator.appVersion.indexOf("MSIE") != -1) { document.write(year); document.write("年"); document.write(month); document.write("月"); document.write(date); document.write("日"); document.write("<br> ") } |
如果浏览器是IE,直接输出今天是“year”+“年”+“month”+“月”+“date”+“日”。 |
if (todayDate.getDay() == 5) document.write("星期五"); if (todayDate.getDay() == 6) document.write("星期六"); if (todayDate.getDay() == 0) document.write("星期日"); if (todayDate.getDay() == 1) document.write("星期一"); if (todayDate.getDay() == 2) document.write("星期二"); if (todayDate.getDay() == 3) document.write("星期三"); if (todayDate.getDay() == 4) document.write("星期四") |
getDay()是Date对象的一种方法,其功能是获得当前是星期几。document.write输出今天是“星期几”。 |
