我在PrePublishCheckList 块

const title =
        typeof coreEditorPostEditsTitle !== "undefined"
            ? coreEditorPostEditsTitle
            : select("core/editor").getCurrentPost().title;

    const [event, setEvent] = useState(2019);
    // todo:: Find a better way to hook after gutenberg loaded and .editor-post-title__input" is available in dom
    setTimeout(() => {
        const editorTitleElement = document.querySelector(
            ".editor-post-title__input"
        );

        if(
            typeof select("core/editor").loadedInit === "undefined" &&
            !title.length
        ) {
            pickDropdownNotice(title);
            // Open right sidebar
            dispatch("core/edit-post").openPublishSidebar();
            // Set default event loadFromApi(event, setEvent);

            select("core/editor").loadedInit = true;
        }

        if(title.length) {
            showEditorTitle(editorTitleElement);
        } else {
            hideEditorTitle(editorTitleElement);
        }
    }, 100);

const showEditorTitle = editorTitleElement => {
    editorTitleElement.style.display = "block";
    editorTitleElement.readOnly = true;
    editorTitleElement.style.background = "#eee";
    editorTitleElement.style.color = "#32373c";
};

const hideEditorTitle = editorTitleElement => {
    editorTitleElement.style.display = "none";
};

代码运行得很好，唯一的问题是我可以找到一个内置钩子来确定".editor-post-title__input" 元素在dom中可用。我知道我可以设置一个超时来反复检查，直到元素在dom中可见为止，但setTimeout感觉像是一个黑客。

还有哪种方法可以替换setTimeout，使setTimeout中的代码仅在.editor-post-title__input" Dom中是否已就绪？

删除setTimeout时出现的错误在hideEditorTitle中TypeError: Cannot read property \'style\' of null 在…上editorTitleElement.style.display = "none"; 内部hideEditorTitle（）
