block-editor-vue

日本語はこちら

"block-editor-vue" is a block editor that allows you to stack any combination of block elements, such as paragraphs, headings, lists, and so on.
Editing content is more flexible when using a WYSIWYG editor such as CKEditor or TinyMCE, but you need to get used to it because you can't move elements intuitively, and garbage markup remains when you delete elements.
Also, if you want to disclose the CMS management screen to a third party, you may need to limit the types of markup that can be used in the page. (For example, you want to allow only headlines, subheadings, and text, but not tables.) I have created a tool for editing HTML markup that is as easy to use as possible and that allows you to set programmable limits on the elements you use.

Usage

Step 1: Link the library to an HTML file

<script src="block-editor-vue.js"></script>

Step 2: Create a starting HTML markup

When you want to input and output data via the INPUT tag

<input name="content" id="editor" type="hidden" value="(Escaped HTML markup)">

The editor receives the HTML markup data set for value attribute and performs the initial display. HTML markup data must have a specific structure for each type.
*to use this feature, set "loadItemsFromInputTag" option true.

When you want to use only the editor without INPUT tag

<div id="editor"></div>

Step 3: Start the library

new BlockEditor('#editor');

When to Set Options

new BlockEditor('#editor', {rootClass: 've'});

Options

Format

new BlockEditor(<element selector>, <options>);

For non-Common options, specify the object whose key is each section name.

  Paragraph: {
    defaultImageAlign: 'right'
  }
