# ngx-clipboard , F.K.A [angular2-clipboard](https://www.npmjs.com/package/angular2-clipboard)

From 6.0.0, there is no other JS dependency anymore. Just Angular.

It works with angular version 2.0.0 and up

To make more sense with the future versioning scheme of Angular, the directive selector is now rename to **ngxClipboard**

## Other packages

-   [ngx-progressive-image-loader](https://github.com/maxisam/ngx-progressive-image-loader): it can lazy load img/picture, prevent reflow and seo friendly.

## Dependencies

 - If you need to use it on 2.x, please use version 7.x.x.
 - If you need to use it on 4.x, please use version 8.x.x.
 - If you need to use it on 5.x, please use version 10.x.x.
 - If you need to use it on 8.x, please use version 12.x.x.
 - If you need to use it on 9.x, please use version 13.x.x.
 - If you need to use it on 10.x - 12.x, please use version 14.x.x.

The code are pretty much the same, in v8.0.0 it uses InjectionToken which requires angular4 and above.

## Install

You can get it on npm.

```bat
npm install ngx-clipboard --save
```

Open your module file e.g `app.module.ts` and update **imports** array

```ts
import { ClipboardModule } from 'ngx-clipboard';
...
imports: [
...
    ClipboardModule,
...
]
```

## Usage

If you use SystemJS to load your files, you might have to update your config:

```js
System.config({
    map: {
        'ngx-clipboard': 'node_modules/ngx-clipboard'
    }
});
```

### Copy source

This library support multiple kinds of copy source.

-   Setting `cbContent` attribute

```html
<button ngxClipboard [cbContent]="'target string'">Copy</button>
```

You can assign the parent **container** to avoid focus trapper issue, #145

```html
<div #container>
    <button ngxClipboard [cbContent]="'target string'" [container]="container">Copy</button>
</div>
```

-   Setting an input target

```html
....

<input type="text" #inputTarget />

<button [ngxClipboard]="inputTarget">Copy</button>
```

-   Using `copy` from `ClipboardService` to copy any text you dynamically created.

```ts
import { ClipboardService } from 'ngx-clipboard'

...

constructor(private _clipboardService: ClipboardService){
...
}

copy(text: string){
  this._clipboardService.copy(text)
}
```

### Callbacks

-   `cbOnSuccess` callback attribute is triggered after copy was successful with `$event: {isSuccess: true, content: string}`

```html
<button (cbOnSuccess)="copied($event)" [cbContent]="'example string'">Copied</button>
```

Or updating parameters directly like so

```html
<button (cbOnSuccess)="isCopied = true" [cbContent]="'example string'">Copied</button>
```

-   `cbOnError` callback attribute is triggered when there's failure in copying with `$event:{isSuccess: false}`

### Conditionally render host

You can also use the structural directive \*ngxClipboardIfSupported to conditionally render the host element

```html
<button ngxClipboard *ngxClipboardIfSupported [cbContent]="'target string'" (cbOnSuccess)="isCopied = true">
    Copy
</button>
```

### Handle copy response globally

To handle copy response globally, you can subscribe to `copyResponse$` exposed by the `ClipboardService`

```
export class ClipboardResponseService {
  constructor(
    private _clipboardService: ClipboardService,
    private _toasterService: ToasterService
  ) {
    this.handleClipboardResponse();
  }

  handleClipboardResponse() {
    this._clipboardService.copyResponse$.subscribe((res: IClipboardResponse) => {
      if (res.isSuccess) {
        this._toasterService.pop('success', undefined, res.successMessage);
      }
    });
  }
}
```

### Clean up temporary textarea used by this module after each copy to clipboard

This library creates a textarea element at the root of the body for its internal use. By default it only destroys it when the directive is destroyed. If you'd like it to be destroyed after each copy to clipboard, provide root level module configuration like this:

```ts
ClipboardService.configure({ cleanUpAfterCopy: true });
```
