| 14 | * quickly. This script should not be seen as part of the calendar. It just |
---|
| 15 | * shows you what one can do with the calendar, while in the same time |
---|
| 16 | * providing a quick and simple method for setting it up. If you need |
---|
| 17 | * exhaustive customization of the calendar creation process feel free to |
---|
| 18 | * modify this code to suit your needs (this is recommended and much better |
---|
| 19 | * than modifying calendar.js itself). |

| 23 | /** |
---|
| 24 | * This function "patches" an input field (or other element) to use a calendar |
---|
| 25 | * widget for date selection. |
---|
| 26 | * |
---|
| 27 | * The "params" is a single object that can have the following properties: |
---|
| 28 | * |
---|
| 29 | * prop. name | description |
---|
| 30 | * ------------------------------------------------------------------------------------------------- |
---|
| 31 | * inputField | the ID of an input field to store the date |
---|
| 32 | * displayArea | the ID of a DIV or other element to show the date |
---|
| 33 | * button | ID of a button or other element that will trigger the calendar |
---|
| 34 | * eventName | event that will trigger the calendar, without the "on" prefix (default: "click") |
---|
| 35 | * ifFormat | date format that will be stored in the input field |
---|
| 36 | * daFormat | the date format that will be used to display the date in displayArea |
---|
| 37 | * singleClick | (true/false) wether the calendar is in single click mode or not (default: true) |
---|
| 38 | * firstDay | numeric: 0 to 6. "0" means display Sunday first, "1" means display Monday first, etc. |
---|
| 39 | * align | alignment (default: "Br"); if you don't know what's this see the calendar documentation |
---|
| 40 | * range | array with 2 elements. Default: [1900, 2999] -- the range of years available |
---|
| 41 | * weekNumbers | (true/false) if it's true (default) the calendar will display week numbers |
---|
| 42 | * flat | null or element ID; if not null the calendar will be a flat calendar having the parent with the given ID |
---|
| 43 | * flatCallback | function that receives a JS Date object and returns an URL to point the browser to (for flat calendar) |
---|
| 44 | * disableFunc | function that receives a JS Date object and should return true if that date has to be disabled in the calendar |
---|
| 45 | * onSelect | function that gets called when a date is selected. You don't _have_ to supply this (the default is generally okay) |
---|
| 46 | * onClose | function that gets called when the calendar is closed. [default] |
---|
| 47 | * onUpdate | function that gets called after the date is updated in the input field. Receives a reference to the calendar. |
---|
| 48 | * date | the date that the calendar will be initially displayed to |
---|
| 49 | * showsTime | default: false; if true the calendar will include a time selector |
---|
| 50 | * timeFormat | the time format; can be "12" or "24", default is "12" |
---|
| 51 | * electric | if true (default) then given fields/date areas are updated for each move; otherwise they're updated only on close |
---|
| 52 | * step | configures the step of the years in drop-down boxes; default: 2 |
---|
| 53 | * position | configures the calendar absolute position; default: null |
---|
| 54 | * cache | if "true" (but default: "false") it will reuse the same calendar object, where possible |
---|
| 55 | * showOthers | if "true" (but default: "false") it will show days from other months too |
---|
| 56 | * |
---|
| 57 | * None of them is required, they all have default values. However, if you |
---|
| 58 | * pass none of "inputField", "displayArea" or "button" you'll get a warning |
---|
| 59 | * saying "nothing to setup". |
