javascript : CalendarView

반응형

The Calendar widget is a JavaScript-based calendar that can either be embedded within a page or popup when a trigger element is clicked. It is based very loosely on the Dynarch Calendar, only in the sense that it was used as a base, but has been almost entirely re-implemented.

Features

  • Developed with CSS in Mind
    In CalendarView you will find no embedded style or presentation. You are encouraged to make it look how you want it to look so that it looks like it belongs in your project.
  • Embedded or Popup — You Decide!
    CalendarView can be either embedded into your page or used as a pop-up. The choice is yours!
  • Lightweight and Easy to Use
    Frustrated with the complexity and bloatedness of existing calendars, CalendarView was implemented as a lightweight alternative.
  • Utilizes the Prototype Framework
    CalendarView uses the Prototype JavaScript framework, lessening the overall JavaScript impact if Prototype is already being used in your project.

Download

CalendarView requires Prototype 1.6.0 (or later).

You may also access the source code at GitHub.

Release History

Version 1.1 — October 19th, 2008

  • Upgraded to Prototype 1.6 and cleaned up code to take full advantage of its new API features.
  • Removed our dependency on Builder from script.aculo.us, as Prototype 1.6 has its own DOM Builder now
  • Fixed a bug where navigating through months of the calendar would display the wrong year when you reached December. Thanks to Dirk Koritnik for the fix and to everyone who reported the issue.

Version 1.0 — March 12th, 2007

  • Initial release

Development Roadmap

  • Add support for assigning an HTML ID and CSS classes to the Calendar at time of creation
  • Reuse Calendar objects for Popup Calendars instead of creating new objects
  • Cleanup, extract, or remove the Date object extensions

Usage Instructions

Options

Option Description
dateField An HTML element (or DOM ID) that will be updated when a date is selected. Can be an INPUT field or any other JavaScript object that has either innerHTML or value attributes. The value of this field will also be parsed for setting the current date when the Calendar is initialized.
triggerElement An HTML element (or DOM ID) that will be observed for clicks to display a popup calendar. If a triggerElement is not specified, the dateField will be observed instead.
parentElement An HTML element (or DOM ID) that will receive the initialized embedded calendar.
selectHandler JavaScript function that will be called when a date is selected. Only define this if you want to override the default behavior.
closeHandler JavaScript function that will be called when the calendar should be closed (either after a selection has been made or if the user clicked outside of the calendar's container element). This only applies to popup calendars and should only be defined if you want to override the default behavior.

Setting up an Embedded Calendar

Embedded calendars require a parent element so that it can be appended to the DOM, such as a div element.

Embedded Calendar Example

<html>
  <head>
    ...
    <script type="text/javascript" src="prototype.js"></script>
    <script type="text/javascript" src="calendarview.js"></script>
    <script type="text/javascript">
      window.onload = function() {
        Calendar.setup({
          dateField     : 'date',
          parentElement : 'calendar'
        })
      }
    </script>
    ...
  </head>
  <body>
    ...
    <div id="calendar"></div>
    <div id="date">Select Date</div>
    ...
  </body>
</html>

Setting up a Popup Calendar

Popup calendars require a trigger element that will display the calendar when clicked. By default, the element defined as the dateField will trigger the calendar if a triggerElement has not been specified.

Popup Calendar Example

<html>
  <head>
    ...
    <script type="text/javascript" src="prototype.js"></script>
    <script type="text/javascript" src="calendarview.js"></script>
    <script type="text/javascript">
      window.onload = function() {
        Calendar.setup({
          dateField      : 'date',
          triggerElement : 'calendarButton'
        })
      }
    </script>
    ...
  </head>
  <body>
    ...
    <input type="text" name="date" id="date" />
    <input type="button" id="calendarButton" value="Show Calendar" />
    ...
  </body>
</html>

Styling the Calendar

The calendar is meant to be styled entirely with CSS. A few CSS classes are declared in the HTML output to assist in styling, but for the most part it should be styled with standard CSS element selectors.

Example HTML Output

<div class="calendar popup">
  <table>
    <thead>
      <tr>
        <td class="title" colspan="7">March 2007</td>
      </tr>

        <td class="button">«</td>
        <td class="button">‹</td>
        <td class="button" colspan="3">Today</td>
