example:
<template>
<MdEditor>
<template #defToolbars>
<NormalToolbar title="mark" @onClick="handler">
<template #trigger>
<svg class="md-editor-icon" aria-hidden="true">
<use xlink:href="#md-editor-icon-mark"></use>
</svg>
</template>
</NormalToolbar>
</template>
</MdEditor>
</template>
<script setup lang="ts">
import { MdEditor, NormalToolbar } from 'md-editor-v3';
import 'md-editor-v3/lib/style.css';
const handler = () => {
console.log('NormalToolbar clicked!');
};
</script>
After 2.5.0, Editor exposes several methods on the instance, used to get or change the internal status of the editor.
<template>
<MdEditor ref="editorRef" />
</template>
<script setup lang="ts">
import { ref, onMounted } from 'vue';
import { MdEditor } from 'md-editor-v3';
import type { ExposeParam } from 'md-editor-v3';
import 'md-editor-v3/lib/style.css';
const editorRef = ref<ExposeParam>();
onMounted(() => {
editorRef.value?.on('catalog', console.log);
editorRef.value?.toggleCatalog(true);
});
</script>
Switched to the opposite status, if toggle without input parameter.
Get the internal state of the editor, including pageFullscreen, fullscreen, preview, htmlPreview, catalog, etc.
type Keys =
| 'pageFullscreen'
| 'fullscreen'
| 'preview'
| 'previewOnly'
| 'htmlPreview'
| 'catalog';
editorRef.value?.on('pageFullscreen', (status) => console.log(status));
Toggle status of fullscreen within the page.
editorRef.value?.togglePageFullscreen(true);
Toggle status of fullscreen widthin browser.
editorRef.value?.toggleFullscreen(true);
Toggle status of preview.
editorRef.value?.togglePreview(true);
Toggle into Preview Only Mode.
editorRef.value?.togglePreviewOnly(true);
Toggle status of htmlPreview.
editorRef.value?.toggleHtmlPreview(true);
Toggle status of catalog.
editorRef.value?.toggleCatalog(true);
Save actions will be triggered.
Manually insert content into textarea.
/**
* @params selectedText
*/
editorRef.value?.insert((selectedText) => {
/**
* @return targetValue Content to be inserted
* @return select Automatically select content, default: true
* @return deviationStart Start position of the selected content, default: 0
* @return deviationEnd End position of the selected content, default: 0
*/
return {
targetValue: `${selectedText}`,
select: true,
deviationStart: 0,
deviationEnd: 0
};
});
For more examples, refer to source code of extension component
Focus on textarea.
import type { FocusOption } from 'md-editor-v3';
const option: FocusOption | undefined = 'start';
// Cursor position when focusing on textarea, default: position when it last lost focus
editorRef.value?.focus(option);
Re render the content.
Get the currently selected text.
Clear current history.
Supports listening to all DOM events.
editorRef.value?.domEventHandlers({
compositionstart: () => {
console.log('compositionstart');
}
});
Insert content into the editor via trigger.
editorRef.value?.execCommand('bold');
Get codemirror instance.
Use config(option: ConfigOption)
to reconfigure markdown-it
and so on.
Warning
We recommend configuring it at the project entry point, such as in main.js
for projects created with Vite. Avoid calling config
within components!
Customize new extensions based on theme and default extensions f codeMirror.
Example: Editor does not render the line number of textarea by default, this extension needs to be manually added
import { config } from 'md-editor-v3';
import { lineNumbers } from '@codemirror/view';
config({
codeMirrorExtensions(_theme, extensions) {
return [...extensions, lineNumbers()];
}
});
Customize extensions, attributes of markdown-it
, etc.
type MarkdownItConfig = (
md: markdownit,
options: {
editorId: string;
}
) => void;
Example: Use markdown-it-anchor
to render a hyperlink symbol to the right of the title
import { config } from 'md-editor-v3';
import ancher from 'markdown-it-anchor';
config({
markdownItConfig(mdit) {
mdit.use(ancher, {
permalink: true
});
}
});
Select and add built-in plugins to markdown-it
.
type MarkdownItPlugins = (
plugins: Array<MarkdownItConfigPlugin>,
options: {
editorId: string;
}
) => Array<MarkdownItConfigPlugin>;
Example: Modify the class name of the image.
import { config } from 'md-editor-v3';
config({
markdownItPlugins(plugins) {
return plugins.map((p) => {
if (p.type === 'image') {
return {
...p,
options: {
...p.options,
classes: 'my-class'
}
};
}
return p;
});
}
});
Add more languages, reset mermaid
template or delay rendering time:
import { config } from 'md-editor-v3';
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,
// for modal component
zIndex: 2000
}
});
Config some dependency libraries, like highlight..
import { config } from 'md-editor-v3';
config({
editorExtensions: { iconfont: 'https://xxx.cc' }
});
『EditorExtensions』
export interface EditorExtensions {
highlight?: {
instance?: any;
js?: string;
css?: {
[key: string]: {
light: string;
dark: string;
};
};
};
prettier?: {
standaloneJs?: string;
parserMarkdownJs?: string;
};
cropper?: {
instance?: any;
js?: string;
css?: string;
};
iconfont?: string;
screenfull?: {
instance?: any;
js?: string;
};
mermaid?: {
instance?: any;
js?: string;
};
katex?: {
instance?: any;
js?: string;
css?: string;
};
}
Synchronously add attributes to the CDN link tags, consistent with the type of editorExtensions
, with a value type of HTMLElementTagNameMap['tagName']
.
import { config, editorExtensionsAttrs } from 'md-editor-v3';
config({
editorExtensionsAttrs
});
Do not attempt to define the src \ onload \ id of the script and rel \ href \ id of the link in editorExtensionsAttrs, as they will be overwritten by default values
Set the way to display icons:
svg
: with symbolclass
: with font-class
If the icon is customized through the attribute customIcon
, the customized icon will be used first.
Configure mermaid
, Details
import { config } from 'md-editor-v3';
config({
mermaidConfig(base: any) {
return {
...base,
logLevel: 'error'
};
}
});
Configure katex
, Details
import { config } from 'md-editor-v3';
config({
katexConfig(base: any) {
return {
...base,
strict: false
};
}
});
Pay attention: shortcut keys are only available when the textarea has received focus!
