js下拉菜单选择日期_jsp中用js实现日期和时间的选择

㈠ js日期下拉框怎么写

ear_month_day.js
function DateSelector(selYear, selMonth, selDay) {
this.selYear = selYear;
this.selMonth = selMonth;
this.selDay = selDay;
this.selYear.Group = this;
this.selMonth.Group = this;
// 给年份、月份下拉菜单添加处理onchange事件的函数
if (window.document.all != null) // IE
{
this.selYear.attachEvent("onchange", DateSelector.Onchange);
this.selMonth.attachEvent("onchange", DateSelector.Onchange);
}
else // Firefox
{
this.selYear.addEventListener("change", DateSelector.Onchange, false);
this.selMonth.addEventListener("change", DateSelector.Onchange, false);
}
if (arguments.length == 4) // 如果传入参数个数为4，最后一个参数必须为Date对象
this.InitSelector(arguments[3].getFullYear(), arguments[3].getMonth() + 1, arguments[3].getDate());
else if (arguments.length == 6) // 如果传入参数个数为6，最后三个参数必须为初始的年月日数值
this.InitSelector(arguments[3], arguments[4], arguments[5]);
else // 默认使用当前日期
{

㈡使用JS实现日期和下拉框的联动~回答得好的追加我所有的分数

CSDN上有，直接使用JS联动技术就可以实现了。

㈢ js 日期下拉框下拉框内容显示日期YYYYMM，要求范围：系统时间前4个月、后8个月。怎么实现

分成年月两个数值即可
取到当前年份、月份，直接
前几个月的处理对月份减1，若回月份变为0，则将年份减1，月答份改为12即可
后几个月的处理对月份加1，若月份变为13，则将年份加1，月份改为1即可
最后组装成需要的字符串即可

也可使用日期对象本身的函数

㈣ js如何创建那个日期选择框啊

给你推荐一个间断兼容性比较好JS代码！

㈤急！如何用js实现联动时间选择框。

㈥ js实现下拉选项默认为当前年月

vardate=newDate();//new一个Date对象
varyear=date.getFullYear();//年份
varmonth=date.getMonth()+1;//月份（从0开始，所以应+1）
for(vari=month;i>month-6;i--){
$("<optionvalue=''>"+year+"年"+i+"月"+"</option>").appendTo($("select"));//依次添加下拉框选项，value自定义，右边的appendTo参数为目标选择框
}

㈦ js日期下拉框默认为本周周一的日期

vardate=newDate();
date.setDate(date.getDate()-date.getDay()+1);
$("#yearoption:contains("+date.getFullYear()+")").prop("selected",true);
$("#monthoption").eq(date.getMonth()+1).prop("selected",true);
$(#dayoption").eq(date.getDate()).prop("selected",true);
date.setDate(date.getDate()+7);
$("#year1option:contains("+date.getFullYear()+")").prop("selected",true);
$("#month1option").eq(date.getMonth()+1).prop("selected",true);
$(#day1option").eq(date.getDate()).prop("selected",true);

顺便说一句：现在通常的做法（也是国际惯例），是把星期日作为一周的开始，而星期六则是周末，如果你想这么做，只需把第二行后面的+1去掉即可。
