        </template>
      </normal-toolbar>
    </template>
  </md-editor>

import MdEditor from 'md-editor-v3';

const NormalToolbar = MdEditor.NormalToolbar;

};
</script>

Events

Config

Use MdEditor.config(option: ConfigOption) to reconfigure renderer.

• markedRenderer: (renderer: RewriteRenderer) => RewriteRenderer

  Open target page in a new browser window:

  MdEditor.config({
    markedRenderer(renderer) {
      renderer.link = (href, title, text) => {
        return `<a href="${href}" title="${title}" target="_blank">${text}</a>`;
      };
  
      return renderer;
    }
  });

  Reference: https://marked.js.org/using_pro#renderer, RewriteRenderer extends Renderer and rewrites heading, now provides index as the fifth parameter.

• markedExtensions: Array<marked.TokenizerExtension & marked.RendererExtension>

  import MdEditor from 'md-editor-v3';
  
  MdEditor.config({
    markedExtensions: [your extension]
  });

  Reference: https://marked.js.org/using_pro#extensions

• markedOptions: marked.MarkedOptions

  Do not render <br> on a single line break:

  import MdEditor from 'md-editor-v3';
  
  MdEditor.config({
    markedOptions: { breaks: false }
  });

  Reference: https://marked.js.org/using_advanced#options

• editorConfig: Add more languages, reset mermaid template or delay rendering time:

  import MdEditor from 'md-editor-v3';
  
  MdEditor.config({
    editorConfig: {
      languageUserDefined: { lang: StaticTextDefaultValue },
      mermaidTemplate: {
        flow: `flow tempalte`,
        ...more
      },
      // Default 500ms. It is set to 0ms when preview only and not set.
      renderDelay: 500
    }
  });

  import MdEditor from 'md-editor-v3';
  
  MdEditor.config({
    editorExtensions: { iconfont: 'https://xxx.cc' }
  });

const text = ref('# Hello Editor');

const onUploadImg = async (files, callback) => {
