| Custom hook `PhxWCHook` for connect custom elements to phoenix. | ||
| This will send and receive event to live view. | ||
|
|
||
| ```js | ||
| const csrfToken = document.querySelector("meta[name='csrf-token']").getAttribute("content"); | ||
|
|
||
| import { PhxWCHook } from "phoenix_webcomponent"; | ||
|
|
||
| const liveSocket = new LiveSocket("/live", Socket, {params: {_csrf_token: csrfToken}, hooks: { PhxWCHook }}); | ||
| ``` | ||
|
|
||
| Send custom events to live view: | ||
| ```html | ||
| <Element phx-wc-send-sync-content="load_content" phx-hook="PhxWCHook" /> | ||
| <Element phx-wc-send-sync-content="load_content;loadAccepted" phx-hook="PhxWCHook" /> | ||
| ``` | ||
| - In the first element, when element trigger customEvents `sync-content`, also use `pushEvent` send `load_content` to live view. | ||
| - Second element are same as first, but will call `loadAccepted` on element when receive server send feedback. | ||
|
|
||
| Receive live view event: | ||
| ```html | ||
| <Element phx-wc-receive-update_content="updateContent" phx-hook="PhxWCHook" /> | ||
| <!-- equal --> | ||
| <Element phx-wc-receive="update_content;updateContent" phx-hook="PhxWCHook" /> | ||
| ``` | ||
| - In this case, when live view fire `update_content` event, also trigger `updateContent` method on elmenet. | ||
| - If value(`updateContent`) is empty, trigger a same event `update_content` on element. | ||
