PC端如何用js做点击日历选中一周
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
js编写一个显示程序运行当天到下一个元旦之间的天数。
下面小编就为大家带来一篇js编写当天简单日历效果【实现代码】。小编觉得挺不错的，现在分享给大家，也给大家做个参考
之前一直很想用javascript写一个日历，但是因为完全没有好的思路， 所以迟迟没有尝试。最近在网上刚好看到用javascript编写的简单日历的例子，代码量虽然不大， 但是我觉得很好地阐述了js日历的实现原理。自己也尝试着做了一下，收获蛮大，掌握了基本的实现原理后，再想增加更多的功能，完全就可以自由发挥了，先在这里分享一下吧，有兴趣的可以试试！
一.表格行数问题
既然要显示日期表格的话，首先得知道这个表格有多少行多少列，列数是已经确定的，从星期天（日历上第1列是星期天）到星期六一共7列。要解决行数问题之前，还得先知道这个月的第1天是星期几，因为每个月的1号并不都是从日历上的星期天开始排的，可能1号是星期五，星期六也说不定，所以1号的左边部分，就得用空表格代替了。那么用多少个空表格代替呢，这里就得用到getDay()方法了，该方法返回数组[0-6]中的一个数字，0代表星期天，1代表星期一，2代表星期二，以此类推。所以如果一个月的1号是星期五的话，那么刚好左边需要5个空表格代替。然后，假如一个月有31天，最后求出的表格行数就是：
var tr_nums = Math.ceil((5 + 31)/7);
当然，并不是每个月都是31天，所以我们得创建一个包含12个月份的数组，每个元素代表每个月份所包含的天数。但是2月份比较特殊，闰年的2月份有29天，平年的2月份只有28天。所以，在创建数组之前，得自己创建一个判断闰年的函数:
//如果当前年份能被4整除但是不能被100整除或者能被400整除，即可确定为闰年，返回1，否则返回0
function isLeap(year) {
return year % 4 == 0 ? (year % 100 != 0 ? 1 : (year % 400 == 0 ? 1 : 0)) : 0;
日历用js如何实现
script src="js/Calendar.js" type="text/javascript" language="javascript"/script
加入到你的页面中 js/Calendar.js 这是控件的路径
input name="txtDate" type="text" onclick="SelectDate(this)" readonly="readonly"
Calendar.js 这个东西应该可以找的到吧，onclick="SelectDate(this)" 这是调用的方法
