以上就是本文的全部内容，希望大家可以轻松实现网页版日历。
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

javascript怎么制作日历控件？
肯定你得设计一个日历控件的界面，关于界面的展现就需要用到CSS和html相关知识和内容了，为了好看，一般都会需要有素材图片。
界面上的设计这个仁者见仁不好说，但是一般都会有的元素有年份、月份选择栏，日期选择栏
还有一个选择之后，日期的值的展示对象（一般是input或者div元素对象na）
确定好这些必要元素后，你就可以考虑与这些对象相关的行为 有哪些，对应的方法是什么。
如果我来做，就会有一个总体的日历类calendar,他包含
init方法初始化（如动态创建日历控件的必要元素，和初始值等，根据已有日期展现控件界面）
dayChoose方法（用户的最终日期选择处理）
monthChoose方法（用户修改月份后界面的改变，界面中日期肯定有变动）
yearChooes方法（用户修改年份后，界面的改变，考虑闰年问题）
当然在具体做的过程中还能抽象出不少相对独立的方法过程。
最好你能去参考网上开源日历控件，看它们的代码，去理解它们的思路，以上想法是我个人简单设想，偏过程化，没有很好的使用面向对象的编程思想
