标签:winform   class   style   代码   java   src   html   使用   问题   

 最近做一个项目的时候需要用到日期选择功能,本以为asp.net会有的,结果发现只有在winform下才可以使用这个datetimePicker,web下并没有提供这个功能。于是Google,网上有很多大牛用不同的方法解决了这个问题,其中有一个是出现率最高的,主要使用js实现,洋洋洒洒近300行的代码,自己实在看不懂,但是只要好用就好了,转载如下。

 

calendar.js

Calendar.htm

 新建一个web.aspx,使用方法如下:

            showy = event.screenY - event.offsetY - 168; // + deltaY;
            newWINwidth = 210 + 4 + 18;
            window.showModalDialog("calendar.htm", obj, "dialogWidth:206px; dialogHeight:230px; dialogLeft:" + showx + "px; dialogTop:" + showy + "px; status:no; directories:yes;scrollbars:no;Resizable=no; ");
