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