  11. * @name DateTime
  12. * @description
  13. * The DateTime component is used to present an interface which makes it easy for
  14. * users to select dates and times. Tapping on `<ion-datetime>` will display a picker
  15. * interface that slides up from the bottom of the page. The picker then displays
  16. * scrollable columns that can be used to individually select years, months, days,
  17. * hours and minute values. The DateTime component is similar to the native
  18. * `<input type="datetime-local">` element, however, Ionic's DateTime component makes
  19. * it easy to display the date and time in a preferred format, and manage the datetime
  20. * values.
  21. *
  22. * ```html
  23. * <ion-item>
  24. * <ion-label>Date</ion-label>
  25. * <ion-datetime displayFormat="MM/DD/YYYY" [(ngModel)]="myDate"></ion-datetime>
  26. * </ion-item>
  27. * ```
  28. *
  29. *
  30. * ## Display and Picker Formats
  31. *
  32. * The DateTime component displays the values in two places: in the `<ion-datetime>`
  33. * component, and in the interface that is presented from the bottom of the screen.
  34. * The following chart lists all of the formats that can be used.
  35. *
  36. * | Format | Description | Example |
  37. * |---------|--------------------------------|-------------------------|
  38. * | `YYYY` | Year, 4 digits | `2018` |
  39. * | `YY` | Year, 2 digits | `18` |
  40. * | `M` | Month | `1` ... `12` |
  41. * | `MM` | Month, leading zero | `01` ... `12` |
  42. * | `MMM` | Month, short name | `Jan` |
  43. * | `MMMM` | Month, full name | `January` |
  44. * | `D` | Day | `1` ... `31` |
  45. * | `DD` | Day, leading zero | `01` ... `31` |
  46. * | `DDD` | Day, short name | `Fri` |
  47. * | `DDDD` | Day, full name | `Friday` |
  48. * | `H` | Hour, 24-hour | `0` ... `23` |
  49. * | `HH` | Hour, 24-hour, leading zero | `00` ... `23` |
  50. * | `h` | Hour, 12-hour | `1` ... `12` |
  51. * | `hh` | Hour, 12-hour, leading zero | `01` ... `12` |
  52. * | `a` | 12-hour time period, lowercase | `am` `pm` |
  53. * | `A` | 12-hour time period, uppercase | `AM` `PM` |
  54. * | `m` | Minute | `1` ... `59` |
  55. * | `mm` | Minute, leading zero | `01` ... `59` |
  56. * | `s` | Second | `1` ... `59` |
  57. * | `ss` | Second, leading zero | `01` ... `59` |
  58. * | `Z` | UTC Timezone Offset | `Z or +HH:mm or -HH:mm` |
  59. *
  60. * **Important**: See the [Month Names and Day of the Week Names](#month-names-and-day-of-the-week-names)
  61. * section below on how to use different names for the month and day.
  62. *
  63. * ### Display Format
  64. *
  65. * The `displayFormat` input property specifies how a datetime's value should be
  66. * printed, as formatted text, within the `ion-datetime` component.
  67. *
  68. * In the following example, the display in the `<ion-datetime>` will use the
  69. * month's short name, the numerical day with a leading zero, a comma and the
  70. * four-digit year. In addition to the date, it will display the time with the hours
  71. * in the 24-hour format and the minutes. Any character can be used as a separator.
  72. * An example display using this format is: `Jun 17, 2005 11:06`.
  73. *
  74. * ```html
  75. * <ion-item>
  76. * <ion-label>Date</ion-label>
  77. * <ion-datetime displayFormat="MMM DD, YYYY HH:mm" [(ngModel)]="myDate"></ion-datetime>
  78. * </ion-item>
  79. * ```
  80. *
  81. * ### Picker Format
  82. *
  83. * The `pickerFormat` input property determines which columns should be shown in the
  84. * interface, the order of the columns, and which format to use within each column.
  85. * If the `pickerFormat` input is not provided then it will default to the `displayFormat`.
  86. *
  87. * In the following example, the display in the `<ion-datetime>` will use the
  88. * `MM/YYYY` format, such as `06/2020`. However, the picker interface
  89. * will display two columns with the month's long name, and the four-digit year.
  90. *
  91. * ```html
  92. * <ion-item>
  93. * <ion-label>Date</ion-label>
  94. * <ion-datetime displayFormat="MM/YYYY" pickerFormat="MMMM YYYY" [(ngModel)]="myDate"></ion-datetime>
  95. * </ion-item>
  96. * ```
  97. *
  98. * ### Datetime Data
  99. *
  100. * Historically, handling datetime values within JavaScript, or even within HTML
  101. * inputs, has always been a challenge. Specifically, JavaScript's `Date` object is
  102. * notoriously difficult to correctly parse apart datetime strings or to format
  103. * datetime values. Even worse is how different browsers and JavaScript versions
  104. * parse various datetime strings differently, especially per locale.
  105. *
  106. * But no worries, all is not lost! Ionic's datetime input has been designed so
  107. * developers can avoid the common pitfalls, allowing developers to easily format
  108. * datetime values within the input, and give the user a simple datetime picker for a
  109. * great user experience.
  110. *
  111. * ##### ISO 8601 Datetime Format: YYYY-MM-DDTHH:mmZ
  112. *
  113. * Ionic uses the [ISO 8601 datetime format](https://www.w3.org/TR/NOTE-datetime)
  114. * for its value. The value is simply a string, rather than using JavaScript's `Date`
  115. * object. Additionally, when using the ISO datetime format, it makes it easier
  116. * to serialize and pass within JSON objects, and sending databases a standardized
  117. * format which it can be easily parsed if need be.
  118. *
  119. * To create an ISO datetime string for the current date and time, e.g. use `const currentDate = (new Date()).toISOString();`.
  120. *
  121. * An ISO format can be used as a simple year, or just the hour and minute, or get more
  122. * detailed down to the millisecond and timezone. Any of the ISO formats below can be used,
  123. * and after a user selects a new value, Ionic will continue to use the same ISO format
  124. * which datetime value was originally given as.
  125. *
  126. * | Description | Format | Datetime Value Example |
  127. * |----------------------|------------------------|------------------------------|
  128. * | Year | YYYY | 1994 |
  129. * | Year and Month | YYYY-MM | 1994-12 |
  130. * | Complete Date | YYYY-MM-DD | 1994-12-15 |
  131. * | Date and Time | YYYY-MM-DDTHH:mm | 1994-12-15T13:47 |
  132. * | UTC Timezone | YYYY-MM-DDTHH:mm:ssTZD | 1994-12-15T13:47:20.789Z |
  133. * | Timezone Offset | YYYY-MM-DDTHH:mm:ssTZD | 1994-12-15T13:47:20.789+5:00 |
  134. * | Hour and Minute | HH:mm | 13:47 |
  135. * | Hour, Minute, Second | HH:mm:ss | 13:47:20 |
  136. *
  137. * Note that the year is always four-digits, milliseconds (if it's added) is always
  138. * three-digits, and all others are always two-digits. So the number representing
  139. * January always has a leading zero, such as `01`. Additionally, the hour is always
  140. * in the 24-hour format, so `00` is `12am` on a 12-hour clock, `13` means `1pm`,
  141. * and `23` means `11pm`.
  142. *
  143. * It's also important to note that neither the `displayFormat` or `pickerFormat` can
  144. * set the datetime value's output, which is the value that is set by the component's
  145. * `ngModel`. The format's are merely for displaying the value as text and the picker's
  146. * interface, but the datetime's value is always persisted as a valid ISO 8601 datetime
  147. * string.
  148. *
  149. *
  150. * ## Min and Max Datetimes
  151. *
  152. * Dates are infinite in either direction, so for a user's selection there should be at
  153. * least some form of restricting the dates that can be selected. By default, the maximum
  154. * date is to the end of the current year, and the minimum date is from the beginning
  155. * of the year that was 100 years ago.
  156. *
  157. * To customize the minimum and maximum datetime values, the `min` and `max` component
  158. * inputs can be provided which may make more sense for the app's use-case, rather
  159. * than the default of the last 100 years. Following the same IS0 8601 format listed
  160. * in the table above, each component can restrict which dates can be selected by the
  161. * user. Below is an example of restricting the date selection between the beginning
  162. * of 2016, and October 31st of 2020:
  163. *
  164. * ```html
  165. * <ion-item>
  166. * <ion-label>Date</ion-label>
  167. * <ion-datetime displayFormat="MMMM YYYY" min="2016" max="2020-10-31" [(ngModel)]="myDate">
  168. * </ion-datetime>
  169. * </ion-item>
  170. * ```
  171. *
  172. *
  173. * ## Month Names and Day of the Week Names
  174. *
  175. * At this time, there is no one-size-fits-all standard to automatically choose the correct
  176. * language/spelling for a month name, or day of the week name, depending on the language
  177. * or locale. Good news is that there is an
  178. * [Intl.DateTimeFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat)
  179. * standard which *most* browsers have adopted. However, at this time the standard has not
  180. * been fully implemented by all popular browsers so Ionic is unavailable to take advantage
  181. * of it *yet*. Additionally, Angular also provides an internationalization service, but it
  182. * is still under heavy development so Ionic does not depend on it at this time.
  183. *
  184. * All things considered, the by far easiest solution is to just provide an array of names
  185. * if the app needs to use names other than the default English version of month and day
  186. * names. The month names and day names can be either configured at the app level, or
  187. * individual `ion-datetime` level.
  188. *
  189. * ### App Config Level
  190. *
  191. * ```ts
  192. * //app.module.ts
  193. * @NgModule({
  194. * ...,
  195. * imports: [
  196. * IonicModule.forRoot(MyApp, {
  197. * monthNames: ['janeiro', 'fevereiro', 'mar\u00e7o', ... ],
  198. * monthShortNames: ['jan', 'fev', 'mar', ... ],
  199. * dayNames: ['domingo', 'segunda-feira', 'ter\u00e7a-feira', ... ],
  200. * dayShortNames: ['dom', 'seg', 'ter', ... ],
  201. * })
  202. * ],
  203. * ...
  204. * })
  205. * ```
  206. *
  207. * ### Component Input Level
  208. *
  209. * ```html
  210. * <ion-item>
  211. * <ion-label>Período</ion-label>
  212. * <ion-datetime displayFormat="DDDD MMM D, YYYY" [(ngModel)]="myDate"
  213. * monthNames="janeiro, fevereiro, mar\u00e7o, ..."
  214. * monthShortNames="jan, fev, mar, ..."
  215. * dayNames="domingo, segunda-feira, ter\u00e7a-feira, ..."
  216. * dayShortNames="dom, seg, ter, ..."></ion-datetime>
  217. * </ion-item>
  218. * ```
  219. *
  220. *
  221. * ### Advanced Datetime Validation and Manipulation
  222. *
  223. * The datetime picker provides the simplicity of selecting an exact format, and persists
  224. * the datetime values as a string using the standardized
  225. * [ISO 8601 datetime format](https://www.w3.org/TR/NOTE-datetime).
  226. * However, it's important to note that `ion-datetime` does not attempt to solve all
  227. * situtations when validating and manipulating datetime values. If datetime values need
  228. * to be parsed from a certain format, or manipulated (such as adding 5 days to a date,
  229. * subtracting 30 minutes, etc.), or even formatting data to a specific locale, then we highly
  230. * recommend using [moment.js](http://momentjs.com/) to "Parse, validate, manipulate, and
  231. * display dates in JavaScript". [Moment.js](http://momentjs.com/) has quickly become
  232. * our goto standard when dealing with datetimes within JavaScript, but Ionic does not
  233. * prepackage this dependency since most apps will not require it, and its locale
  234. * configuration should be decided by the end-developer.
  235. *
  236. *
  237. * @usage
  238. * ```html
  239. * <ion-item>
  240. * <ion-label>Date</ion-label>
  241. * <ion-datetime displayFormat="MM/DD/YYYY" [(ngModel)]="myDate">
  242. * </ion-datetime>
