`function getNowFormatDate() {`

`    ` `var`  `date = ` `new`  `Date();`

`    ` `var`  `seperator1 = ` `"-"` `;`

`    ` `var`  `seperator2 = ` `":"` `;`

`    ` `var`  `month = date.getMonth() + 1;`

`    ` `var`  `strDate = date.getDate();`

`    ` `if`  `(month >= 1 && month <= 9) {`

`        ` `month = ` `"0"`  `+ month;`

`    ` `}`

`    ` `if`  `(strDate >= 0 && strDate <= 9) {`

`        ` `strDate = ` `"0"`  `+ strDate;`

`    ` `}`

`    ` `var`  `currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate`

`            ` `+ ` `" "`  `+ date.getHours() + seperator2 + date.getMinutes()`

`            ` `+ seperator2 + date.getSeconds();`

`    ` `return`  `currentdate;`

`}`

js中获得当前时间是年份和月份，形如：201208  
        
 //获取完整的日期  
 var date=new Date;  
 var year=date.getFullYear();   
 var month=date.getMonth()+1;  
 month =(month<10 ? "0"+month:month);   
 var mydate = (year.toString()+month.toString());

注意，year.toString()+month.toString()不能写成year+month。不然如果月份大于等于10，则月份为数字，会和年份相加，如201210，则会变为2022，需要加.toString()

以下是搜到的有用内容：

var myDate = new Date();  
myDate.getYear(); //获取当前年份(2位)  
myDate.getFullYear(); //获取完整的年份(4位,1970-????)  
myDate.getMonth(); //获取当前月份(0-11,0代表1月)  
myDate.getDate(); //获取当前日(1-31)  
myDate.getDay(); //获取当前星期X(0-6,0代表星期天)  
myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)  
myDate.getHours(); //获取当前小时数(0-23)  
myDate.getMinutes(); //获取当前分钟数(0-59)  
myDate.getSeconds(); //获取当前秒数(0-59)  
myDate.getMilliseconds(); //获取当前毫秒数(0-999)  
myDate.toLocaleDateString(); //获取当前日期  
var mytime=myDate.toLocaleTimeString(); //获取当前时间  
myDate.toLocaleString( ); //获取日期与时间

<SCRIPT LANGUAGE="JavaScript">  
function monthnow()\{  
 var now   = new Date();  
 var monthn = now.getMonth();  
 var yearn  = now.getYear();  
 window.location.href="winnNamelist.jsp?getMonth="+monthn+"&getYear="+yearn;  
\}  
</script>
