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