一直想搞一个纯前端的markdown编辑器+解析器。
将个人博客zzzmh.cn 的文章语法用markdown实现。
既可以大幅节省写文章耗费时间，也能通用到简书或思否。
试了多个纯前端markdown库以后，感觉simpleMDE的用法最简单，效果也与简书等最为接近。

入门款demo
只需要引入CSS、JS、一个textarea标签即可。无其他依赖。

主要用到的配置
- 启用预览模式
- 启用自动保存(每秒保存到localstorage，防刷新后丢失)
- 启用代码高亮
- 启用自定义地址的font-awesome

稍微复制一些说明文档中主要的配置参数说明
(在下英语水平有限，翻译就免了，交给有道翻译吧)
autoDownloadFontAwesome: If set to true, force downloads Font Awesome (used for icons). If set to false, prevents downloading. Defaults to undefined, which will intelligently check whether Font Awesome has already been included, then download accordingly.
autofocus: If set to true, autofocuses the editor. Defaults to false.
autosave: Saves the text that's being written and will load it back in the future. It will forget the text when the form it's contained in is submitted.
- enabled: If set to
true, autosave the text. Defaults tofalse. - delay: Delay between saves, in milliseconds. Defaults to
10000(10s). - uniqueId: You must set a unique string identifier so that SimpleMDE can autosave. Something that separates this from other instances of SimpleMDE elsewhere on your website.
blockStyles: Customize how certain buttons that style blocks of text behave.
- bold Can be set to
**or__. Defaults to**. - code Can be set to
```or~~~. Defaults to```. - italic Can be set to
*or_. Defaults to*.
element: The DOM element for the textarea to use. Defaults to the first textarea on the page.
forceSync: If set to true, force text changes made in SimpleMDE to be immediately stored in original textarea. Defaults to false.
hideIcons: An array of icon names to hide. Can be used to hide specific icons shown by default without completely customizing the toolbar.
indentWithTabs: If set to false, indent using spaces instead of tabs. Defaults to true.
initialValue: If set, will customize the initial value of the editor.
insertTexts: Customize how certain buttons that insert text behave. Takes an array with two elements. The first element will be the text inserted before the cursor or highlight, and the second element will be inserted after. For example, this is the default link value: ["[", "](http://)"].
- horizontalRule
- image
- link
- table
lineWrapping: If set to false, disable line wrapping. Defaults to true.
parsingConfig: Adjust settings for parsing the Markdown during editing (not previewing).
- allowAtxHeaderWithoutSpace: If set to
true, will render headers without a space after the#. Defaults tofalse. - strikethrough: If set to
false, will not process GFM strikethrough syntax. Defaults totrue. - underscoresBreakWords: If set to
true, let underscores be a delimiter for separating words. Defaults tofalse.
placeholder: Custom placeholder that should be displayed
previewRender: Custom function for parsing the plaintext Markdown and returning HTML. Used when user previews.
promptURLs: If set to true, a JS alert window appears asking for the link or image URL. Defaults to false.
renderingConfig: Adjust settings for parsing the Markdown during previewing (not editing).
- singleLineBreaks: If set to
false, disable parsing GFM single line breaks. Defaults totrue. - codeSyntaxHighlighting: If set to
true, will highlight using highlight.js. Defaults tofalse. To use this feature you must include highlight.js on your page. For example, include the script and the CSS files like:
shortcuts: Keyboard shortcuts associated with this instance. Defaults to the array of shortcuts.
showIcons: An array of icon names to show. Can be used to show specific icons hidden by default without completely customizing the toolbar.
spellChecker: If set to false, disable the spell checker. Defaults to true.
status: If set to false, hide the status bar. Defaults to the array of built-in status bar items.
- Optionally, you can set an array of status bar items to include, and in what order. You can even define your own custom status bar items.
styleSelectedText: If set to false, remove the CodeMirror-selectedtext class from selected lines. Defaults to true.
tabSize: If set, customize the tab size. Defaults to 2.
toolbar: If set to false, hide the toolbar. Defaults to the array of icons.
toolbarTips: If set to false, disable toolbar button tips. Defaults to true.
顺便说下这个工具有什么用哈
一般个人建博客站，如果是不用hexo、wp的话，就需要自己写个后台新增编辑文章，这样一来可能每篇文章就都需要用html语法来写大量代码，消耗不少时间，还不能实时查看效果。用本工具既可以用在后台的文章编辑，也可以把编辑器配置成页面显示，直接渲染出html代码。从而大幅缩减开发时间和编辑文章的时间。写出来的内容语法和简书、思否等一致都是markdown，复制过来也完美兼容
