/**
|
||||
* Builders to use Select2 in our templates.
|
||||
*
|
||||
* This comes with two flavours : local data or remote data.
|
||||
*
|
||||
* # Local data source
|
||||
*
|
||||
* To use local data source, you must define an array
|
||||
* in your JS code, having the fields `id` and `text`.
|
||||
*
|
||||
* ```js
|
||||
* const data = [
|
||||
* {id: 1, text: "foo"},
|
||||
* {id: 2, text: "bar"},
|
||||
* ];
|
||||
* document.addEventListener("DOMContentLoaded", () => sithSelect2({
|
||||
* element: document.getElementById("select2-input"),
|
||||
* data_source: local_data_source(data)
|
||||
* }));
|
||||
* ```
|
||||
*
|
||||
* You can also define a callback that return ids to exclude :
|
||||
*
|
||||
* ```js
|
||||
* const data = [
|
||||
* {id: 1, text: "foo"},
|
||||
* {id: 2, text: "bar"},
|
||||
* {id: 3, text: "to exclude"},
|
||||
* ];
|
||||
* document.addEventListener("DOMContentLoaded", () => sithSelect2({
|
||||
* element: document.getElementById("select2-input"),
|
||||
* data_source: local_data_source(data, {
|
||||
* excluded: () => data.filter((i) => i.text === "to exclude").map((i) => parseInt(i))
|
||||
* })
|
||||
* }));
|
||||
* ```
|
||||
*
|
||||
* # Remote data source
|
||||
*
|
||||
* Select2 with remote data sources are similar to those with local
|
||||
* data, but with some more parameters, like `result_converter`,
|
||||
* which takes a callback that must return a `Select2Object`.
|
||||
*
|
||||
* ```js
|
||||
* document.addEventListener("DOMContentLoaded", () => sithSelect2({
|
||||
* element: document.getElementById("select2-input"),
|
||||
* data_source: remote_data_source("/api/user/search", {
|
||||
* excluded: () => [1, 2], // exclude users 1 and 2 from the search
|
||||
* result_converter: (user) => Object({id: user.id, text: user.first_name})
|
||||
* })
|
||||
* }));
|
||||
* ```
|
||||
*
|
||||
* # Overrides
|
||||
*
|
||||
* Dealing with a select2 may be complex.
|
||||
* That's why, when defining a select,
|
||||
* you may add an override parameter,
|
||||
* in which you can declare any parameter defined in the
|
||||
* Select2 documentation.
|
||||
*
|
||||
* ```js
|
||||
* document.addEventListener("DOMContentLoaded", () => sithSelect2({
|
||||
* element: document.getElementById("select2-input"),
|
||||
* data_source: remote_data_source("/api/user/search", {
|
||||
* result_converter: (user) => Object({id: user.id, text: user.first_name}),
|
||||
* overrides: {
|
||||
* delay: 500
|
||||
* }
|
||||
* })
|
||||
* }));
|
||||
* ```
|
||||
*
|
||||
* # Caveats with exclude
|
||||
*
|
||||
* With local data source, select2 evaluates the data only once.
|
||||
* Thus, modify the exclude after the initialisation is a no-op.
|
||||
*
|
||||
* With remote data source, the exclude list will be evaluated
|
||||
* after each api response.
|
||||
* It makes it possible to bind the data returned by the callback
|
||||
* to some reactive data, thus making the exclude list dynamic.
|
||||
*
|
||||
* # Images
|
||||
*
|
||||
* Sometimes, you would like to display an image besides
|
||||
* the text on the select items.
|
||||
* In this case, fill the `picture_getter` option :
|
||||
*
|
||||
* ```js
|
||||
* document.addEventListener("DOMContentLoaded", () => sithSelect2({
|
||||
* element: document.getElementById("select2-input"),
|
||||
* data_source: remote_data_source("/api/user/search", {
|
||||
* result_converter: (user) => Object({id: user.id, text: user.first_name})
|
||||
* })
|
||||
* picture_getter: (user) => user.profile_pict,
|
||||
* }));
|
||||
* ```
|
||||
*
|
||||
* # Binding with alpine
|
||||
*
|
||||
* You can declare your select2 component in an Alpine data.
|
||||
*
|
||||
* ```html
|
||||
* <body>
|
||||
* <div x-data="select2_test">
|
||||
* <select x-ref="search" x-ref="select"></select>
|
||||
* <p x-text="current_selection.id"></p>
|
||||
* <p x-text="current_selection.text"></p>
|
||||
* </div>
|
||||
* </body>
|
||||
*
|
||||
* <script>
|
||||
* document.addEventListener("alpine:init", () => {
|
||||
* Alpine.data("select2_test", () => ({
|
||||
* selector: undefined,
|
||||
* current_select: {id: "", text: ""},
|
||||
*
|
||||
* init() {
|
||||
* this.selector = sithSelect2({
|
||||
* element: $(this.$refs.select),
|
||||
* data_source: local_data_source(
|
||||
* [{id: 1, text: "foo"}, {id: 2, text: "bar"}]
|
||||
* ),
|
||||
* });
|
||||
* this.selector.on("select2:select", (event) => {
|
||||
* // select2 => Alpine signals here
|
||||
* this.current_select = this.selector.select2("data")
|
||||
* });
|
||||
* this.$watch("current_selected" (value) => {
|

* // Alpine => select2 signals here
