Often use Google's friends must be vivid memories of Google Calendar control it, then we also to achieve a, although the function and effect is not comparable, but the important thing is the process of implementation.
here is the HTML structure to implement:
<div id= "A" ><div id= "head" ><span id= "Yface" > Years: <select id= "Year" ></select></span ><span id= "Mface" > Month: <select id= "month" ></select></span></div><div id= "Biaoti" ></div><div id= "Body" ></div></div>
First, the algorithm of the calendar query:
W=y+parseint (Y/4) +parseint (C/4) -2*c+parseint (26* (m+1)/10) +d-1;
The following is a detailed description of the process, interested can go to see:

The following are the implemented JavaScript code:

The entry parameter is the HTML object to bind, which is typically text input.
Here is the calling code:
<title>untitled document</title>
<body>
<script src= "Kongjian.js" ></script>
<input type= "text" id= "a" >
<script>
Sx.activex.calender.bind (document.getElementById ("a"));
</script>
</body>
Almost so, the code is more verbose, not very good, if a friend has a better way, please communicate with me a lot ah.
