| /** | ||
| * Alpine.js Directive: `x-bind-change-set` | ||
| * | ||
| * This directive allows you to synchronize form elements with a given changeSet object. | ||
| * It is designed to work with different form input types including text inputs, | ||
| * textareas, checkboxes, and file inputs. | ||
| * | ||
| * ## Parameters | ||
| * | ||
| * - `el`: The DOM element this directive is attached to. | ||
| * - `expression`: The JavaScript expression passed to the directive, evaluated to get the changeSet object. | ||
| * - `value`: Optional parameter to specify the field name. Defaults to the `name` attribute of the element. | ||
| * - `modifiers`: Array of additional modifiers to customize the behavior. For instance, use 'single' for single-file uploads. | ||
| * - `evaluate`: Function to evaluate Alpine.js expressions. | ||
| * - `cleanup`: Function to remove event listeners when element is destroyed or directive is unbound. | ||
| * | ||
| * ## Events | ||
| * | ||
| * This directive emits a custom event named "csupdate" whenever the changeSet object or the form element is updated. | ||
| * | ||
| * ## Usage | ||
| * | ||
| * ### Example in HTML | ||
| * | ||
| * ```html | ||
| * <select name="lectureHallId" x-bind-change-set="changeSet"> | ||
| * <option value="0">Self streaming</option> | ||
| * <!-- ... other options ... --> | ||
| * </select> | ||
| * ``` | ||
| * | ||
| * - `changeSet`: The changeSet object you want to bind with the form element. | ||
| * | ||
| * ## Modifiers | ||
| * | ||
| * - `single`: Use this modifier for file inputs when you want to work with a single file instead of a FileList. | ||
| * - `int`: Use this modifier to convert the inserted value to integer. | ||
| * - `float`: Use this modifier to convert the inserted value to float. | ||
| * | ||
| * ```html | ||
| * <input type="file" x-bind-change-set.single="changeSet" /> | ||
| * ``` | ||
| * | ||
| * ## Notes | ||
| * | ||
| * This directive is intended to be used with the existing `ChangeSet` class. | ||
| * Make sure to import and initialize a `ChangeSet` object in your Alpine.js component | ||
| * to utilize this directive effectively. The `ChangeSet` class should have implemented | ||
| * methods such as `patch`, `listen`, `removeListener`, and `get`, | ||
| * and manage a `DirtyState` object for tracking changes. | ||
