"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". */ Calendar.setup = function (params) { function param_default(pname, def) { if (typeof params[pname] == "undefined") { params[pname] = def; } }; param_default("inputField", null); param_default("displayArea", null); param_default("button", null); param_default("eventName", "click"); param_default("ifFormat", "%Y/%m/%d"); param_default("daFormat", "%Y/%m/%d"); param_default("singleClick", true); param_default("disableFunc", null); param_default("dateStatusFunc", params["disableFunc"]); // takes precedence if both are defined param_default("dateText", null); param_default("firstDay", null); param_default("align", "Br"); param_default("range", [2000, 2999]); param_default("weekNumbers", false); param_default("flat", null); param_default("flatCallback", null); param_default("onSelect", null); param_default("onClose", null); param_default("onUpdate", null); param_default("date", null); param_default("showsTime", false); param_default("timeFormat", "24"); param_default("electric", true); param_default("step", 2); param_default("position", null); param_default("cache", false); param_default("showOthers", false); param_default("multiple", null); var tmp = ["inputField", "displayArea", "button"]; for (var i in tmp) { if (typeof params[tmp[i]] == "string") { params[tmp[i]] = document.getElementById(params[tmp[i]]); } } if (!(params.flat || params.multiple || params.inputField || params.displayArea || params.button)) { alert("Calendar.setup:\n Nothing to setup (no fields found).
