JqueryUI - Datepicker
Datepickers in jQueryUI allow users to enter dates easily and visually. You can customize the date format and language, restrict the selectable date ranges and add in buttons and other navigation options easily.jQueryUI provides datepicker() method that creates a datepicker and changes the appearance of HTML elements on a page by adding new CSS classes. Transforms the <input>, <div>, and <span> elements in the wrapped set into a datepicker control.
By default, for <input> elements, the datepicker calendar opens in a small overlay when the associated text field gains focus. For an inline calendar, simply attach the datepicker to a <div>, or <span> element.
Syntax
The datepicker() method can be used in two forms −- $(selector, context).datepicker (options) Method
- $(selector, context).datepicker ("action", [params]) Method
$ (selector, context).datepicker (options) Method
The datepicker (options) method declares that an <input> element (or <div>, or <span>, depending on how you choose to display the calendar) should be managed as a datepicker. The options parameter is an object that specifies the behavior and appearance of the datepicker elements.Syntax
$(selector, context).datepicker(options);You can provide one or more options at a time using Javascript object. If there are more than one options to be provided then you will separate them using a comma as follows −
$(selector, context).datepicker({option1: value1, option2: value2..... });The following table lists the different options that can be used with this method −
Sr.No. | Option & Description |
---|---|
1 | altField
This option specifies a jQuery selector for a field that is also updated with any date selections. The altFormat
option can be used to set the format for this value. This is quite
useful for setting date values into a hidden input element to be
submitted to the server, while displaying a more user-friendly format to
the user. By default its value is "". |
2 | altFormat
This option is used when an altField option is specified. It provides the format for the value to be written to the alternate element. By default its value is "". |

element, intended to show instructions to the user. By default its value
is "". |

to accommodate the datepicker’s date format as set with the dateFormat
option. By default its value is false. |
5 | beforeShow

datepicker is displayed, with the <input> element and datepicker
instance passed as parameters. This function can return an options hash

6 | beforeShowDay
This option is a callback function which takes a date as
parameter, that’s invoked for each day in the datepicker just before
