Ion2 Datetime Picker--An Ionic2 Custom Datetime Picker Component based on
[ion-multi-picker](https://github.com/raychenfj/ion-multi-picker) by [raychenfj](https://github.com/raychenfj)
Simulate IOS date and time column pickers by ionic2 picker. Default
[Ionic DateTime Component](http://ionicframework.com/docs/v2/api/components/datetime/DateTime/) work with
only independent columns that has some validation problems. Also there is
[min and max issue](https://github.com/driftyco/ionic/issues/6850) with time validation.
This one helps to solve these problems.
**Note: [MomentJS](http://momentjs.com/) requred for using some features of the package**

## Installation
```
npm install ion2-datetime-picker --save
```
## Usage
1.Import MultiPickerModule to your app/module.
```Typescript
import { MultiPickerModule } from 'ion2-datetime-picker';
@NgModule({
declarations: [
MyApp,
AboutPage,
ContactPage,
HomePage,
TabsPage,
],
imports: [
IonicModule.forRoot(MyApp),
MultiPickerModule //Import MultiPickerModule
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
AboutPage,
ContactPage,
HomePage,
TabsPage,
],
providers: []
})
export class AppModule {}
```
2.Add ion-multi-picker to your html template.
```html
Simple TimePicker
```
**Note: Don't miss the `item-content` attribute**
Like other ionic components, you can use `[formControl]` to bind your data.
```typescript
import { FormBuilder, FormGroup } from '@angular/forms';
...
constructor() {
this.formGroup = new FormBuilder().group({
time: [moment().format()]
});
}
```
```html
Default Value
```
Set `type` to `date` to use datepicker.
```html
Disabled Picker
```

| max | Validation maximum attribute | ISO 8601 String or moment.Moment | | time | End of the year that follows the current 2 years |

## Exceptions
If for some reason, all the possible
values of the column are non-valid, this exception is raised:
* `Ion2 datetime picker: column " " should have at least one option` -
## Utils
You can use some utils methods:
```typescript
import { MultiPickerUtils } from 'ion2-datetime-picker';
let variable = MultiPickerUtils.minuteRound('2016-12-10T11:32:44+03:00', 15);
```
* minuteRound(val: string\|moment.Moment, rounding: number): moment.Moment
Returns nearest from below moment for *val* with minutes that multiple for *rounding*

Fork and `git clone` this project,
most code for the multi picker is under `src/app/components/multi-picker`.
The unit test framework is karma + webpack + jasmine. And e2e test is protractor.
Add your unit test and use `npm test` to start karma.
Debug your unit test using `npm run test-watch` and open `http://localhost:9876/debug.html`
Add your e2e test, run `ionic serve` and then in another terminal use `npm run e2e` to run protractor.
You can also add your use case in the `app/pages`.
Finally, send me a `PULL REQUEST`.
