# faux-anchor
[![Build Status][ci-img]][ci] [![BrowserStack Status][browserstack-img]][browserstack]
Improve anchor and non-anchor elements with primary and secondary actions and callbacks.
When run on anchor elements, it "hijacks" standard action and gives you option of running some operation (e.g. logging some statistics, sending analytics data, executing long AJAX request, …) before primary or while secondary action is performed.
When run on non-anchor elements like buttons or standard tag elements, it tries to apply same heuristics like on anchor elements (e.g. middle mouse button click, return key, combination with meta modifier key, …) to provide (nearly) same behavior. Note that not all actions can be perfomed similarly due to nature of different [browser][caveat-1] [behavior][caveat-2].
## Install
```sh
npm install faux-anchor --save
```## Usage
Default structure for faux anchor.
```html
jackielexie
``````js
import fauxanchor from 'faux-anchor';
const anchorElement = document.querySelector('.jackie');
const tagElement = document.querySelector('.lexie');
const statsLogger = () => Promise.resolve();const anchorInstance = fauxanchor(anchorElement, {
onPrimaryAction: ( e ) => {
// Called on primary action (e.g. left mouse button click)
// Example: Log some stats;
// Return Promise to proceed with native/simulated behavior if it resolves
return statsLogger();},
onSecondaryAction: ( e ) => {
// Called on secondary action (e.g. middle mouse button click)
// Return Promise to proceed with native/simulated behavior if it resolves
return Promise.resolve();
}
});const tagInstance = fauxanchor(tagElement);
```## API
### fauxanchor(element[, options])
Returns: `Object`
When run on anchor elements, `href` and `target` attributes are used. When run on non-anchor elements, `data-href` and `data-target` attributes are used.
There is also support for `rel`/`data-rel` attribute, particularly [`noopener` value due to security issues][noopener-security].
#### element
Type: `Element`
Element on which to apply changes.
#### options
Type: `Object`
##### onPrimaryAction
Type: `Function`
Default: `( e ) => Promise.resolve()`Callback for primary action (e.g. left mouse button click). This is usually action triggered in the same window.
Return `Promise` to proceed with native/simulated behavior.
Function arguments:
* **e** `Event` Event which triggered callback
##### onSecondaryAction
Type: `Function`
Default: `( e ) => Promise.resolve()`Callback for secondary action (e.g. middle mouse button click). For anchor elements this is usually new window opened via browser native heuristics, and for non-anchor elements `window.open` is used where possible.
Return `Promise` to proceed with native/simulated behavior.
Function arguments:
* **e** `Event` Event which triggered callback
##### focusUnfocusable
Type: `Boolean`
Default: `true`Should the unfocusable element (e.g. generic tag) be focusable.
##### primaryActionHandler
Type: `Function`
Default: `( href ) => window.location.assign(href)`Set primary action handler. Useful if you want to handle primary actions with client-side router.
### instance.destroy()
Destroy instance.
## Test
For automated tests, run `npm run test:automated`.
For manual tests, run `npm run test:manual` and open in your browser.
## Browser support
Tested in IE9+ and all modern browsers. `Promise` should be available globally.
