最近一直都在使用 Angular
进行开发,维护项目。遇到了日期的问题,同事采用的是 @danielmoncada/angular-datetime-picker。
PS:当然,如果是新项目,还是建议使用框架集成的日期功能,虽然功能可能不是你的预期,但是起码够用。比如 ant design
的 angular
版本。
当然,angular-datetime-picker
提供了很多属性和事件。比如:
owl-date-time
的属性有:
属性名称
| 类型
| 是否必要
| 默认值
|
pickerType
| both , calendar , timer | 可选
| both |
yearOnly
| 布尔值
| 可选
| false |
其他的属性和方法请前往官网查看
当然,本文我们并不是探讨这些简单更改属性和方法的需求。我们来讨论两点:
- 在输入框中显示
YYYY/MM/ HH:mm:ss
格式 - 翻译 - 更改按钮的名称
Cancel => 取消
,Set => 设置
目前默认的值是这样的:
我们有相关的 html
代码如下:
<ng-container>
<input
element-id="date-time-picker"
class="form-control"
(ngModelChange)="goToDate($event)"
[min]="minDate" [max]="maxDate"
[owlDateTimeTrigger]="dt"
[(ngModel)]="selectedMoment"
[owlDateTime]="dt">
<owl-date-time #dt [showSecondsTimer]="true"></owl-date-time>
</ng-container>
设置时间格式
在 app.module.ts
中引入:
import {OwlDateTimeModule, OwlMomentDateTimeModule, OWL_DATE_TIME_FORMATS} from '@danielmoncada/angular-datetime-picker';
// https://danielykpan.github.io/date-time-picker/#locale-formats
// 自定义格式化时间
export const MY_MOMENT_FORMATS = {
fullPickerInput: 'YYYY/MM/DD HH:mm:ss', // 指定的时间格式
datePickerInput: 'YYYY/MM/DD',
timePickerInput: 'HH:mm:ss',
monthYearLabel: 'YYYY/MM',
dateA11yLabel: 'YYYY/MM/DD',
monthYearA11yLabel: 'YYYY/MM',
};
@NgModule({
imports: [
OwlDateTimeModule,
OwlMomentDateTimeModule
],
providers: [
{provide: OWL_DATE_TIME_FORMATS, useValue: MY_MOMENT_FORMATS
],
})
export class AppModule
得到的结果图如下:
翻译按钮
我们需要用到这个包的国际化,将对应的 Cancel
翻译成 取消
,Set
翻译成 设置
。
官网已经介绍:
import { NgModule } from '@angular/core';
import { OwlDateTimeModule, OwlNativeDateTimeModule, OwlDateTimeIntl} from 'ng-pick-datetime';
// here is the default text string
export class DefaultIntl extends OwlDateTimeIntl = {
/** A label for the up second button (used by screen readers). */
upSecondLabel= 'Add a second',
/** A label for the down second button (used by screen readers). */
downSecondLabel= 'Minus a second',
/** A label for the up minute button (used by screen readers). */
upMinuteLabel= 'Add a minute',
/** A label for the down minute button (used by screen readers). */
downMinuteLabel= 'Minus a minute',
/** A label for the up hour button (used by screen readers). */
upHourLabel= 'Add a hour',
/** A label for the down hour button (used by screen readers). */
downHourLabel= 'Minus a hour',
/** A label for the previous month button (used by screen readers). */
prevMonthLabel= 'Previous month',
/** A label for the next month button (used by screen readers). */
nextMonthLabel= 'Next month',
/** A label for the previous year button (used by screen readers). */
prevYearLabel= 'Previous year',
/** A label for the next year button (used by screen readers). */
nextYearLabel= 'Next year',
/** A label for the previous multi-year button (used by screen readers). */
prevMultiYearLabel= 'Previous 21 years',
/** A label for the next multi-year button (used by screen readers). */
nextMultiYearLabel= 'Next 21 years',
/** A label for the 'switch to month view' button (used by screen readers). */
switchToMonthViewLabel= 'Change to month view',
/** A label for the 'switch to year view' button (used by screen readers). */
switchToMultiYearViewLabel= 'Choose month and year',
/** A label for the cancel button */
cancelBtnLabel= 'Cancel',
/** A label for the set button */
setBtnLabel= 'Set',
/** A label for the range 'from' in picker info */
rangeFromLabel= 'From',
/** A label for the range 'to' in picker info */
rangeToLabel= 'To',
/** A label for the hour12 button (AM) */
hour12AMLabel= 'AM',
/** A label for the hour12 button (PM) */
hour12PMLabel= 'PM',
};
@NgModule({
imports: [
OwlDateTimeModule,
OwlNativeDateTimeModule
],
providers: [
{provide: OwlDateTimeIntl, useClass: DefaultIntl},
],
})
export class AppExampleModule
我们按照上面的思路整合下来实现我们的需求:
新建翻译文件 owl-date-time-translator.ts
import { Injectable } from '@angular/core';
import { DefaultTranslationService } from '@services/translation.service';
import { OwlDateTimeIntl } from '@danielmoncada/angular-datetime-picker';
@Injectable()
export class OwlDateTimeTranslator extends OwlDateTimeIntl {
constructor(protected) {
super();
/** 取消按钮 */
this.cancelBtnLabel = this.translationService.translate('action.cancel');
/** 设置按钮 */
this.setBtnLabel = this.translationService.translate('action.set');
}
};
这里我们引入了翻译服务 translationService
,可以根据不同地区进行语言选择。
然后我们在 app.module.ts
上操作:
import { OwlDateTimeIntl } from '@danielmoncada/angular-datetime-picker';
// 翻译 @danielmoncada/angular-datetime-picker
import { OwlDateTimeTranslator } from './path/to/owl-date-time-translator';
@NgModule({
providers: [
{provide: OwlDateTimeIntl, useClass: OwlDateTimeTranslator},
],
})
export class AppModule
得到的效果图如下:
