    editor() {
      // get current editor object
      return this.$refs.myEditor.editor
    }
  },
  mounted() {
    // use editor object...
    this.editor.focus()
    console.log('this is current editor object', this.editor)
  }

## Using Language Modes and Addons

CodeMirror 中包含了许多的语言模式

默认情况下所有的语言模式和插件在默认的情况下没有加载， 启用它们：

 - 安装 `vue-codemirror-lite`
 - require `vue-codemirror-lite` 后 require 一个语言模式或者插件
 - 在 options 对象中配置 mode 选项

```html
<template>
  <codemirror :options="{
    mode: 'javascript',
    extraKeys: {'Ctrl-Space': 'autocomplete'}
  }"></codemirror>
</template>

<script>
  import { codemirror } from 'vue-codemirror-lite'
  require('codemirror/mode/javascript/javascript')
  require('codemirror/mode/vue/vue')

  require('codemirror/addon/hint/show-hint.js')
  require('codemirror/addon/hint/show-hint.css')
  require('codemirror/addon/hint/javascript-hint.js')

  export default {
    ...
  }
</script>
```
