Attributes
Attribute | Req/Opt | Default | Description |
name | Required | The name of the calendar. | |
dayNames | Optional | S, M, T, W, Th, F, S | A comma-delimited list that sets the names of the weekdays displayed in the calendar. Sunday is the first day and the rest of the weekday names follow in the normal order. |
disabled | Optional | Not disabled | Disables all user input, making the control read-only. To disable input, specify disabled without an attribute or disabled="Yes" (or any ColdFusion positive boolean value, such as true). To enable input, omit the attribute or specify disabled="No" (or any ColdFusion negative Boolean value, such as false). |
enabled | Optional | yes | Flash only: Boolean value that specifies whether the control is enabled. A disabled control appears in light gray. This is the inverse of the disabled attribute. |
endRange | Optional | The end of a range of dates that are disabled. Users cannot select dates from the date specified by the startRange attribute through this date. | |
firstDayOfWeek | Optional | 0 | Integer in the range 0-6 specifying the first day of the week in the calendar: 0 indicates Sunday; 6 indicates Saturday. |
height | Optional | Determined by Flash | The vertical dimension of the calendar specified in pixels. |
mask | Optional | MM/DD/YYYY | A pattern that specifies the format of the submitted date. Mask characters are:
|
monthNames | Optional | January, February, March, April, May, June, July, August, September, October, November, December | A comma-delimited list of the month names that are displayed at the top of the calendar. |
onBlur | Optional | ActionScript that runs when the calendar loses focus. | |
onChange | Optional | ActionScript that runs when the user selects a date. | |
onFocus | Optional | ActionScript that runs when the calendar gets focus. | |
selectedDate | Optional | None (Flash shows the current month) | The date that is initially selected. It is highlighted in a color determined by the form skin. Must be in mm/dd/yyyy or dd/mm/yyyy format, depending on the current locale. (Use the setlocale function to set the locale, if necessary.) |
startRange | Optional | The start of a range of dates that are disabled. Users cannot select dates from this date through the date specified by the endRange attribute. | |
style | Optional | Flash ActionScript style or styles to apply to the calendar. For more information, see Setting styles and skins in Flash forms in the Developing ColdFusion Applications. | |
tooltip | Optional | Flash only: Text to display when the mouse pointer hovers over the control. | |
visible | Optional | yes | Flash only: Boolean value that specifies whether to show the control. Space that would be occupied by an invisible control is blank. |
width | Optional | Determined by Flash | The horizontal dimension of the calendar specified in pixels. |
Usage
The cfcalendar tag displays a calendar month, showing the month, the year, a grid of the days of the month, and headings for the days of the week. The calendar contains forward and back arrow buttons to let you change the month and year that are displayed.
If you include a value for the selectedDate attribute, that date is highlighted in green and determines the month and year that display initially. Changing the month and year display does not change the selected date. A user can change the selected date by clicking a different date on the calendar. The onChange attribute can specify an ActionScript event handler function that runs when the user selects a date.
The current date is highlighted in reverse (that is, a white number on a black background). If the selected date is in a different month or year, however, the current date does not appear unless you move to it by clicking the forward or back arrows.
The mask attribute lets you specify the format of the selected date that is returned to the application.
You can use the keyboard to access and select dates from a cfcalendar control:

You can use the keyboard to access and select dates from a cfcalendar control:
- Use the Up, Down, Left, and Right Arrow keys to change the selected date.
- Use the Home and End keys to reach the first and last enabled date in a month, respectively.
- Use the Page Up and Page Down keys to reach the previous and next month, respectively.The cfcalendar tag is not supported in XML format forms.
Example
This example produces a 200-pixel by 150-pixel calendar with a Flash haloBlue skin. It displays abbreviated month names and two-character days of the week. It initially displays today's date as determined by the selectedDate attribute. When you click the Save button, the form submits back to the current page, which displays the submitted information.
The example also has three dateField controls that let the user change the initial selected date that displays on the calendar and a blocked-out date range. The initial blocked-out date is a four-day period immediately preceding today's date.
The example also has three dateField controls that let the user change the initial selected date that displays on the calendar and a blocked-out date range. The initial blocked-out date is a four-day period immediately preceding today's date.
Note: This example must be modified to work in locales that do not use mm/dd/yyyy date formats. To do so, use the LSDateFormat function in place of the DateFormat function and a mask that is appropriate for your locale, such as dd/mm/yyyy.
