带日程的js日历_如何用JS写一个日历

① 求一款js做的时间日历控件

这是我找到的一个js做的日历，不知道是不是你要的，里面有包含时间，其实在日历里面加时间也是比较简单的，只要调用DATE的方法就可以了，希望对你有用。下面是代码段，效果图附上。

③ 日历js怎么写

加入到你的页面中js/Calendar.js这是控件的路径Calendar.js这个东西应该可以找的到吧，onclick="SelectDate(this)"这是调用的方法

④ 如何用JS写一个日历

首先必须解决的问题是表格的行与列问题。列是固定的，七列，因为一周有七天。行需要动态计算，因为，每一个月的第一天是星期几是一个变数，因而第一天在表格中的第几个单元也就跟着变化，同时，每个月的总天数不一致也影响着各个月对表格行数的需要量。

一. 表格的行数问题

1.首先取得处理月的总天数

JS不提供此参数，我们需要计算。考虑到闰年问题会影响二月份的天数，我们先编写一个判断闰年的自编函数：

function is_leap(year) {
return (year%100==0?res=(year%400==0?1:0):res=(year%4==0?1:0));
}

接着定义一个包含十二个月在内的月份总天数的数组：

m_days=new Array(31,28+is_leap(ynow),31,30,31,31,30,31,30,31,30,31);

m_days这个数组里，二月份的天数已经加入闰年的信息：28+is_leap(ynow)。数组元素从0开始，正好对应于JS提供的Date函数提供的getMonth返回值，即0表示一月，1表示二月，2表示三月，依此类推。

这样，各月总数可以这样取得：m_days[x]。其中，x为0至11的自然数。

2.计算处理月第一天是星期几

可以使用Date函数的getDay取得，返回的值从0到6，0表示星期一，1表示星期二，2表示星期三，其余依此类推。代码如下（假设要处理的时间为2008年3月）：

n1str=new Date(2008,3,1);
firstday=n1str.getDay();

有了月总天数和该月第一天是星期几这两个已知条件，就可以解决表格所需行数问题：（当前月天数+第一天是星期几的数值）除以七。表格函数需要整数，因此，我们使用Math.ceil来处理：

tr_str=Math.ceil((m_days[mnow] + firstday)/7);

表格中的tr标签实际上代表表格的行，因此变量tr_str是我们往下写表格的重要依据。

二. 打印日历表格

可以使用两个for语句嵌套起来实现：外层for语句写行，内层for语句写单元格。

for(i=0;i<tr_str;i++) { //外层for语句 - tr标签
document.write("<tr>");
for(k=0;k<7;k++) { //内层for语句 - td标签
idx=i*7+k; //表格单元的自然序号
date_str=idx-firstday+1; //计算日期
//这里是处理有效日期代码
} //内层for语句结束
document.write("</tr>");
} //外层for语句结束

单元格的自然序号是否代表有效日期非常关键，为此必须加入一个过滤机制：仅打印有效的日期。有效的日期大于0小于小于等于处理月的总天数。

⑥ JS,Javascript,编程日历制作思路

去年末我复自己写了个jquery的日历插件制，我当时的思路是这样的：
1，获取每月第一天是星期几 eg:3
2，获取每月多少天 eg:30
然后循环，30天，循环30次，循环每次加1就不用说了然后把每个值放进表格的td里面
然后获取上个月和下个月有多少天，按照上月自减和下月自加的方式把其他表格内容补齐，这样一个完整的以月为单元的日历就行了

⑦ 有谁给提供一个带周的js日历啊，能够选择一年中的第几周

http://time.rootinfo.com.tw/main.html

这个可以选择第几周的~！

⑧ 想用js做日历怎么弄

1.写一个获取当前时间的脚本
2.写一个获取事件源绝对坐标的脚本
3.写一个日历生成脚本，根据年(闰年)月(大小月)周(周一到周日)生成日历
4.当事件源(一般是文本框)获得焦点的时候，触发获取绝对坐标的事件，然后生成当前月的日历，将此日历的坐标用脚本移动到文本框下方
5.生成日历的时候，给所有日添加返回事件，把当前选中的年月日反馈
6.用脚本把反馈回来的日期信息，写入事件源控件

7.网上日历控件一大堆，最好别自己写，很容易蛋疼的

⑨ js设置日历选择范围，并且开始时间不能大于截止时间

// 初始化时间设置

var DateRange = {

startTime：“2016-02”，

endTime：“2017-07”

}；

$(".workload [name = 'startMonth']").datepicker({

"startView":1,

minViewMode:1,

format:"yyyy-mm",

'endDate':DateRange.endTime,

'startDate':DateRange.startTime

}).on('changeDate',function(e){

var startTime = e.date;

$(".workload [name = 'endMonth']").datepicker('setStartDate',startTime);

})；

$(".workload [name = 'endMonth']").datepicker({

"startView":1,

minViewMode:1,

format:"yyyy-mm",

'maxDate':DateRange.endTime,

'minDate':DateRange.startTime

}).on('changeDate',function(e){

var endTime = e.date;

$(".workload [name = 'startMonth']").datepicker('setEndDate',endTime);

})；

⑩ js实现日历可获得指定日期周数及星期几示例分享(js获取星期几)

应为要有交互，选择了Js来实现，也算是
结对编程
的初试吧。
我将显示部分用html
写好，点击的按钮触发事件函数是check()；
复制代码
代码如下:
function
onCheck(){
var
Year
=
document.getElementById("year").value;
//获取文本框的“年”
var
theYear
=Year
*
1;
//转换为number类型
//alert(theYear);
//
获取月值
var
month
=
document.getElementById("month");
var
index1=month.selectedIndex;
var
theMonth
=
month.options[index1].value;
//获取月值
var
day
=
document.getElementById("day");
var
index2=day.selectedIndex;
var
theDay
=
day.options[index2].value;
//
输入值判断部分
...
//调用核心函数
days(theYear,theMonth,theDay);
}
