Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. 'Name' is the name of the icon, referenced in the JS. 'Action' is either a function or a URL to open. 'Class' is the class given to the icon. 'Tooltip' is the small tooltip that appears via the `title='` attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a keybind assigned to it (i.e. with the value of `action` set to `bold` and that of `tooltip` set to `Bold`, the final text the user will see would be 'Bold (Ctrl-B)').

Additionally, you can add a separator between any icons by adding `'|'` to the toolbar array.

Name | Action | Tooltip<br>Class

:--- | :----- | :--------------

bold | toggleBold | Bold<br>fa fa-bold

italic | toggleItalic | Italic<br>fa fa-italic

strikethrough | toggleStrikethrough | Strikethrough<br>fa fa-strikethrough

Customize the toolbar using the `toolbar` option like:

export default {

data () {

return {

configs: {

toolbar: ['bold', 'italic', 'heading', '|', 'quote']

}

}

}

}

export default {

data () {

return {

configs: {

toolbar: [{

name: 'bold',

action: SimpleMDE.toggleBold,

className: 'fa fa-bold',

title: 'Bold'

},

{

name: 'custom',

action: function customFunction(editor){

// Add your own code

},

className: 'fa fa-star',

title: 'Custom Button'

},

'|' // Separator

...

]

}

}

}

}

simplemde带有预定义键盘快捷键的数组，可以用一个配置选项改变。默认的列表如下：

快捷键 | 操作

:------- | :-----

*Cmd-'* | 'toggleBlockquote'

*Cmd-B* | '加粗'

*Cmd-E* | 'cleanBlock'

*Cmd-H* | '降低标题级别'

*Cmd-I* | '斜体'

*Cmd-K* | '插入链接'

*Cmd-L* | '插入无序列表'

*Cmd-P* | '预览'

*Cmd-Alt-C* | '插入代码块'

*Cmd-Alt-I* | '插入图片'

*Cmd-Alt-L* | '插入有序列表'

*Shift-Cmd-H* | '提高标题级别'

*F9* | '全屏预览'

*F11* | '全屏'

可以只修改部分快捷键，其他保持不变：

export default {

data () {

return {

configs: {

shortcuts: {

'toggleOrderedList': 'Ctrl-Alt-K', // 改变插入有序列表的快捷

'toggleCodeBlock': null, // 不绑定插入代码块的快捷键

'drawTable': 'Cmd-Alt-T' // 绑定没有预设快捷键的操作，插入表格

}

}

}

}

}

快捷键会在平台之间自动转换。如果你定义一个快捷键为“Cmd-B”，在PC机上的快捷键将更改为“Ctrl-B”。反之亦然。

可以绑定的操作列表与[工具栏按钮](#toolbar-icons)的内置操作列表相同。

改变最小高度:

.markdown-editor .CodeMirror, .markdown-editor .CodeMirror-scroll {

min-height: 200px;

}

设置高度为一个固定值:

.markdown-editor .CodeMirror {

height: 300px;

}
