Js获取当前日期时间

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

//当月天数

var curMonthDays = new Date(myDate.getFullYear(), (myDate.getMonth()+1), 0).getDate();

*/

当月天数

var curMonthDays = new Date(myDate.getFullYear(), (myDate.getMonth()+1), 0).getDate();

通过JQ生成年月日下拉框数据，支持定位功能

jS部分：

var year = 2005;

var month = 12;

var day = 20;

{literal}

$(document).ready(function(){

set_date_select(year,month,day);

$(’#month’).change(function(){

var tmp_year = $(”#year”).val();

var tmp_month = $(”#month”).val();

set_date_select(tmp_year,tmp_month,0);

});

});

function set_date_select(year,month,day){

$(”#year”).empty();

$(”#month”).empty();

$(”#day”).empty();

//年

var myDate = new Date();

var year_num = myDate.getFullYear()-1900+1;

for(var i=0;i<year_num;i++){

var tmp_year = 1900+i;

if(tmp_year == year )

$(’#year’).append(”<option value=’”+tmp_year+”‘ selected=’selected’>”+tmp_year+”</option>”);

else

$(’#year’).append(”<option value=’”+tmp_year+”‘>”+tmp_year+”</option>”);

}

//月

for(var i=1;i<=12;i++){

if(i == month)

$(’#month’).append(”<option value=’”+i+”‘ selected=’selected’>”+i+”</option>”);

else

$(’#month’).append(”<option value=’”+i+”‘>”+i+”</option>”);

}

//当月天数

var curMonthDays = 31;

if(month > 0 && month <= 12){

var curMonthDays = new Date(myDate.getFullYear(), ( month ), 0).getDate();

}

//日

for(var i=1;i<=curMonthDays;i++){

if(i == day)

$(’#day’).append(”<option value=’”+i+”‘ selected=’selected’>”+i+”</option>”);

else

$(’#day’).append(”<option value=’”+i+”‘ >”+i+”</option>”);

}

}

HTML部分:

<select name=”year” id=”year”></select>

<select name=”month” id=”month”></select>

<select name=”day” id=”day”></select>
