  22. * The {@glink builds/guides/overview#inline-editor inline editor} implementation.
  23. * It uses an inline editable and a floating toolbar.
  24. * See the {@glink examples/builds/inline-editor demo}.
  25. *
  26. * In order to create a inline editor instance, use the static
  27. * {@link module:editor-inline/inlineeditor~InlineEditor.create `InlineEditor.create()`} method.
  28. *
  29. * # Inline editor and inline build
  30. *
  31. * The inline editor can be used directly from source (if you installed the
  32. * [`@ckeditor/ckeditor5-editor-inline`](https://www.npmjs.com/package/@ckeditor/ckeditor5-editor-inline) package)
  33. * but it is also available in the {@glink builds/guides/overview#inline-editor inline build}.
  34. *
  35. * {@glink builds/guides/overview Builds} are ready-to-use editors with plugins bundled in. When using the editor from
  36. * source you need to take care of loading all plugins by yourself
  37. * (through the {@link module:core/editor/editorconfig~EditorConfig#plugins `config.plugins`} option).
  38. * Using the editor from source gives much better flexibility and allows easier customization.
  39. *

  93. * Creates a new inline editor instance.
  94. *
  95. * There are three general ways how the editor can be initialized.
  96. *
  97. * # Using an existing DOM element (and loading data from it)
  98. *
  99. * You can initialize the editor using an existing DOM element:
  100. *
  101. * InlineEditor
  102. * .create( document.querySelector( '#editor' ) )
  103. * .then( editor => {
  104. * console.log( 'Editor was initialized', editor );
  105. * } )
  106. * .catch( err => {
  107. * console.error( err.stack );
  108. * } );
  109. *
  110. * The element's content will be used as the editor data and the element will become the editable element.
  111. *
  112. * # Creating a detached editor
  113. *
  114. * Alternatively, you can initialize the editor by passing the initial data directly as a `String`.
  115. * In this case, the editor will render an element that must be inserted into the DOM for the editor to work properly:
  116. *
  117. * InlineEditor
  118. * .create( '<p>Hello world!</p>' )
  119. * .then( editor => {
  120. * console.log( 'Editor was initialized', editor );
  121. *
  122. * // Initial data was provided so the editor UI element needs to be added manually to the DOM.
  123. * document.body.appendChild( editor.ui.element );
  124. * } )
  125. * .catch( err => {
  126. * console.error( err.stack );
  127. * } );
  128. *
  129. * This lets you dynamically append the editor to your web page whenever it is convenient for you. You may use this method if your
  130. * web page content is generated on the client side and the DOM structure is not ready at the moment when you initialize the editor.
  131. *
  132. * # Using an existing DOM element (and data provided in `config.initialData`)
  133. *
  134. * You can also mix these two ways by providing a DOM element to be used and passing the initial data through the configuration:
  135. *
  136. * InlineEditor
  137. * .create( document.querySelector( '#editor' ), {
  138. * initialData: '<h2>Initial data</h2><p>Foo bar.</p>'
  139. * } )
  140. * .then( editor => {
  141. * console.log( 'Editor was initialized', editor );
  142. * } )
  143. * .catch( err => {
  144. * console.error( err.stack );
  145. * } );
  146. *
  147. * This method can be used to initialize the editor on an existing element with the specified content in case if your integration
  148. * makes it difficult to set the content of the source element.
  149. *
  150. * Note that an error will be thrown if you pass the initial data both as the first parameter and also in the configuration.
  151. *
  152. * # Configuring the editor
  153. *
  154. * See the {@link module:core/editor/editorconfig~EditorConfig editor configuration documentation} to learn more about
  155. * customizing plugins, toolbar and more.
  156. *
  157. * # Using the editor from source
  158. *
  159. * The code samples listed in the previous sections of this documentation assume that you are using an
  160. * {@glink builds/guides/overview editor build} (for example – `@ckeditor/ckeditor5-build-inline`).
  161. *
  162. * If you want to use the inline editor from source (`@ckeditor/ckeditor5-editor-inline/src/inlineeditor`),
  163. * you need to define the list of
  164. * {@link module:core/editor/editorconfig~EditorConfig#plugins plugins to be initialized} and
  165. * {@link module:core/editor/editorconfig~EditorConfig#toolbar toolbar items}. Read more about using the editor from
  166. * source in the {@glink builds/guides/integration/advanced-setup "Advanced setup" guide}.
  167. *
  168. * @param {HTMLElement|String} sourceElementOrData The DOM element that will be the source for the created editor
  169. * or the editor's initial data.
  170. *
  171. * If a DOM element is passed, its content will be automatically loaded to the editor upon initialization.
  172. * Moreover, the editor data will be set back to the original element once the editor is destroyed.
  173. *
  174. * If the initial data is passed, a detached editor will be created. In this case you need to insert it into the DOM manually.
  175. * It is available under the {@link module:editor-inline/inlineeditorui~InlineEditorUI#element `editor.ui.element`} property.
  176. *
  177. * @param {module:core/editor/editorconfig~EditorConfig} [config] The editor configuration.
  178. * @returns {Promise} A promise resolved once the editor is ready. The promise resolves with the created editor instance.
