js 获取当前月天数

Javascript获取当月的天数: var d = new Date();//d.getMonth()+1代表下个月,月份索引从0开始,即当前月为6月时,getMonth()返回值为5,创建日期时同理//此处构造的日期为下个月的第0天,天数索引从1开始,第0天即代表上个月的最后一天var cur...

示例代码如下: JS 获取当月天数function getDays(){//构造当前日期对象var date = new Date();//获取年份var year = date.getFullYear();//获取当前月份var mouth = date.getMonth() + 1;//定义当月的天数;var days ;//当月份为二月时,根据闰...

var getLastDays = function(){ var now = new Date; now.setMonth(now.getMonth() - 1); now.setDate(1); var next = new Date; next.setDate(1); var arr = []; while(now < next){ arr.push(now.getDate()); now.setDate(now.getDate() + 1);...

var date = new Date(); date.setDate(1); var weekday=new Array(7); weekday[0]="星期日" ; weekday[1]="星期一"; weekday[2]="星期二"; weekday[3]="星期三"; weekday[4]="星期四"; weekday[5]="星期五"; weekday[6]="星期六"; alert("本月...

function getCountDays() { var curDate = new Date(); /* 获取当前月份 */ var curMonth = curDate.getMonth(); /* 生成实际的月份: 由于curMonth会比实际月份小1, 故需加1 */ curDate.setMonth(curMonth + 1); /* 将日期设置为0, 这里为什么要...

使用Date对象可以获取时间相关的信息。 获取当前时间: 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(); va...

//获取多久以前,比如1秒前、一分钟前、一天前,等等function getTimeFormat(startTime) { var startTimeMills = startTime.getTime(); var endTimeMills = new Date().getTime(); var diff = parseInt((endTimeMills - startTimeMills) / 1000)...

用Globalization包的类,比如: 如果用公历就是 GregorianCalendar gc = new GregorianCalendar(); int year = 2003; int month = 7; int days = gc.GetDaysInMonth(year,month);

var now=new Date();var nowDate=new Date(nowDate.getFullYear(),nowDate.getMonth(),nowDate.getDate());var preDate=new Date(nowDate.getFullYear(),nowDate.getMonth()-6,nowDate.getDate());var days=(nowDate.getTime()-preDate.getTime(...

1.把开始时间和结束时间保存 var dateFrom = new Date(strFrom); var dateTo = new Date(strTo); 2.计算时间差 var diff = dateTo.valueOf() - dateFrom.valueOf(); 3.时间差转换为天数 var diff_day = parseInt(diff/(1000*60*60*24));
