24 /**
25 * This function "patches" an input field (or other element) to use a calendar
26 * widget for date selection.
27 *
28 * The "params" is a single object that can have the following properties:
29 *
30 * prop. name | description
31 * -------------------------------------------------------------------------------------------------
32 * inputField | the ID of an input field to store the date
33 * displayArea | the ID of a DIV or other element to show the date
34 * button | ID of a button or other element that will trigger the calendar
35 * eventName | event that will trigger the calendar, without the "on" prefix (default: "click")
36 * ifFormat | date format that will be stored in the input field
37 * daFormat | the date format that will be used to display the date in displayArea
38 * singleClick | (true/false) wether the calendar is in single click mode or not (default: true)
39 * firstDay | numeric: 0 to 6. "0" means display Sunday first, "1" means display Monday first, etc.
40 * align | alignment (default: "Br"); if you don't know what's this see the calendar documentation
41 * range | array with 2 elements. Default: [1900, 2999] -- the range of years available
42 * weekNumbers | (true/false) if it's true (default) the calendar will display week numbers
43 * flat | null or element ID; if not null the calendar will be a flat calendar having the parent with the given ID
44 * flatCallback | function that receives a JS Date object and returns an URL to point the browser to (for flat calendar)
45 * disableFunc | function that receives a JS Date object and should return true if that date has to be disabled in the calendar
46 * onSelect | function that gets called when a date is selected. You don't _have_ to supply this (the default is generally okay)
47 * onClose | function that gets called when the calendar is closed. [default]
48 * onUpdate | function that gets called after the date is updated in the input field. Receives a reference to the calendar.
49 * date | the date that the calendar will be initially displayed to
50 * showsTime | default: false; if true the calendar will include a time selector
51 * timeFormat | the time format; can be "12" or "24", default is "12"
52 * electric | if true (default) then given fields/date areas are updated for each move; otherwise they're updated only on close
53 * step | configures the step of the years in drop-down boxes; default: 2
54 * position | configures the calendar absolute position; default: null
55 * cache | if "true" (but default: "false") it will reuse the same calendar object, where possible
56 * showOthers | if "true" (but default: "false") it will show days from other months too
57 *
58 * None of them is required, they all have default values. However, if you
59 * pass none of "inputField", "displayArea" or "button" you'll get a warning
60 * saying "nothing to setup".
