javascript calendar reminder system (compatible with all browsers)_time and date

Function introduction:
1. Normal calendar function.
2. Wait etc
3. Receive array
For example:

Copy code The code is as follows:

new Calendar("id").show(
{
"20091120": "What did you do today...",
"2009320": "What did you do today? . . "
}
);

Calendar reminder styles are divided into 3 categories.
a. Today
b. Prompt style for the current month of the year
c. Prompt style for the current month
The prompt content will automatically appear when the mouse is over the date with the prompt
4. . . . .
Mainly divided into 2 uses.
1. Provide a div or other element and pass the container's id to Calendar. The method name is: show()
Example: var cr = Calendar("div1");
cr.show( /*data - This array is optional, if passed there will be a prompt Function */ );
2. Provide an input[type='text'] element and pass the element's id to Calendar. The method name is: pop()
Example: var cr = Calendar("input2");
cr.pop();
Not much else to say. If you think it's good, support it. hehe.
If you have any questions or good ideas, please let me know. Thank you
Detailed usage and examples are in the compressed package.
