20 * This function "patches" an input field (or other element) to use a calendar
21 * widget for date selection.
23 * The "params" is a single object that can have the following properties:
25 * prop. name | description
26 * -------------------------------------------------------------------------------------------------
27 * inputField | the ID of an input field to store the date
28 * displayArea | the ID of a DIV or other element to show the date
29 * button | ID of a button or other element that will trigger the calendar
30 * eventName | event that will trigger the calendar, without the "on" prefix (default: "click")
31 * ifFormat | date format that will be stored in the input field
32 * daFormat | the date format that will be used to display the date in displayArea
33 * singleClick | (true/false) wether the calendar is in single click mode or not (default: true)
34 * mondayFirst | (true/false) if true Monday is the first day of week, Sunday otherwise (default: false)
35 * align | alignment (default: "Bl"); if you don't know what's this see the calendar documentation
36 * range | array with 2 elements. Default: [1900, 2999] -- the range of years available
37 * weekNumbers | (true/false) if it's true (default) the calendar will display week numbers
38 * flat | null or element ID; if not null the calendar will be a flat calendar having the parent with the given ID
39 * flatCallback | function that receives a JS Date object and returns an URL to point the browser to (for flat calendar)
40 * disableFunc | function that receives a JS Date object and should return true if that date has to be disabled in the calendar
42 * None of them is required, they all have default values. However, if you
43 * pass none of "inputField", "displayArea" or "button" you'll get a warning
44 * saying "nothing to setup".
