What is the purpose of these functions? As provided isMinDate returns true if there is no minimum date or the current date is greater than or equal to the minimum!

[Jörn Zaefferer]

Deferred, unclear usecase.

using examples

jQuery.validator.addMethod("dateMin",

function (value, element, param) {

if (value == ""

!param) return true;

return $(element).datepicker('isMinDate');

}, "Please enter valid date."

);

jQuery.validator.addMethod("dateMax",

function (value, element, param) {

if (value == ""

!param) return true;

return $(element).datepicker('isMaxDate');

}, "Please enter valid date."

);

jQuery.validator.addMethod("k2dateRange",

function (value, element, param) {

if (value == ""

!param) return true;

return $(element).datepicker('isDateInRange');

}, "Please enter valid date."

);

jQuery.validator.addMethod("k2date",

function(value, element, param) {

if (!param) return true; needed for validatorCondition to work

return this.optional(element)

$(element).datepicker('isValidDate');

}, "Please enter a valid date."

);

example 2 - datepicker ranges

$('d_start_from').datepicker({'minDate':$.datepicker.parseDate("yy-mm-dd", "2008-11-13"),'beforeShow':function () { return {'maxDate':$("#d_end_to").datepicker("getMinMaxRangeDate", "max")}; }}); $('d_end_to').datepicker({'maxDate':$.datepicker.parseDate("yy-mm-dd", "2010-12-31"),'beforeShow':function () { return {'minDate':$("#d_start_from").datepicker("getMinMaxRangeDate", "min")}; }});

your custom range example is not ok, when datepickers have date limits code from example function customRange(input) {

return {minDate: (input.id == "endDate" ? $("#startDate").datepicker("getDate") : null),

maxDate: (input.id == "startDate" ? $("#endDate").datepicker("getDate") : null)};

)

These can be implemented as extensions.
