54 Roo.extend(Roo.form.DateField, Roo.form.TriggerField, {
56 * @cfg {String} format
57 * The default date format string which can be overriden for localization support. The format must be
58 * valid according to {@link Date#parseDate} (defaults to 'm/d/y').
62 * @cfg {String} altFormats
63 * Multiple date formats separated by "|" to try when parsing a user input value and it doesn't match the defined
64 * format (defaults to 'm/d/Y|m-d-y|m-d-Y|m/d|m-d|d').
66 altFormats : "m/d/Y|m-d-y|m-d-Y|m/d|m-d|md|mdy|mdY|d",
68 * @cfg {Array} disabledDays
69 * An array of days to disable, 0 based. For example, [0, 6] disables Sunday and Saturday (defaults to null).
73 * @cfg {String} disabledDaysText
74 * The tooltip to display when the date falls on a disabled day (defaults to 'Disabled')
76 disabledDaysText : "Disabled",
78 * @cfg {Array} disabledDates
79 * An array of "dates" to disable, as strings. These strings will be used to build a dynamic regular
80 * expression so they are very powerful. Some examples:
82 * <li>["03/08/2003", "09/16/2003"] would disable those exact dates</li>
83 * <li>["03/08", "09/16"] would disable those days for every year</li>
84 * <li>["^03/08"] would only match the beginning (useful if you are using short years)</li>
85 * <li>["03/../2006"] would disable every day in March 2006</li>
86 * <li>["^03"] would disable every day in every March</li>
88 * In order to support regular expressions, if you are using a date format that has "." in it, you will have to
89 * escape the dot when restricting dates. For example: ["03\\.08\\.03"].
93 * @cfg {String} disabledDatesText
94 * The tooltip text to display when the date falls on a disabled date (defaults to 'Disabled')
96 disabledDatesText : "Disabled",
98 * @cfg {Date/String} minValue
99 * The minimum allowed date. Can be either a Javascript date object or a string date in a
100 * valid format (defaults to null).
104 * @cfg {Date/String} maxValue
105 * The maximum allowed date. Can be either a Javascript date object or a string date in a
106 * valid format (defaults to null).
110 * @cfg {String} minText
111 * The error text to display when the date in the cell is before minValue (defaults to
112 * 'The date in this field must be after {minValue}').
114 minText : "The date in this field must be equal to or after {0}",
116 * @cfg {String} maxText
117 * The error text to display when the date in the cell is after maxValue (defaults to
118 * 'The date in this field must be before {maxValue}').
120 maxText : "The date in this field must be equal to or before {0}",
122 * @cfg {String} invalidText
123 * The error text to display when the date in the field is invalid (defaults to
124 * '{value} is not a valid date - it must be in the format {format}').
126 invalidText : "{0} is not a valid date - it must be in the format {1}",
128 * @cfg {String} triggerClass
129 * An additional CSS class used to style the trigger button. The trigger will always get the
130 * class 'x-form-trigger' and triggerClass will be <b>appended</b> if specified (defaults to 'x-form-date-trigger'
131 * which displays a calendar icon).
133 triggerClass : 'x-form-date-trigger',
137 * @cfg {Boolean} useIso
138 * if enabled, then the date field will use a hidden field to store the
139 * real value as iso formated date. default (false)
143 * @cfg {String/Object} autoCreate
144 * A DomHelper element spec, or true for a default element spec (defaults to
145 * {tag: "input", type: "text", size: "10", autocomplete: "off"})
148 defaultAutoCreate : {tag: "input", type: "text", size: "10", autocomplete: "off"},
