在vue项目中使用codemirror插件实现代码编辑器功能

<template> <textarea ref="mycode" class="codesql" v-model="code" style="height:200px;width:600px;"></textarea></template><script>import "codemirror/theme/ambiance.css";import "codemirror/lib/codemirror.css";import "codemirror/addon/hint/show-hint.css";let CodeMirror = require("codemirror/lib/codemirror");require("codemirror/addon/edit/matchbrackets");require("codemirror/addon/selection/active-line");require("codemirror/mode/sql/sql");require("codemirror/addon/hint/show-hint");require("codemirror/addon/hint/sql-hint"); export default {   name: "codeMirror",  data () {   return {    code: '//按Ctrl键进行代码提示'   }  },  mounted () {   debugger   let mime = 'text/x-mariadb'   //let theme = 'ambiance'//设置主题，不设置的会使用默认主题   let editor = CodeMirror.fromTextArea(this.$refs.mycode, {    mode: mime,//选择对应代码编辑器的语言，我这边选的是数据库，根据个人情况自行设置即可    indentWithTabs: true,    smartIndent: true,    lineNumbers: true,    matchBrackets: true,    //theme: theme,    // autofocus: true,    extraKeys: {'Ctrl': 'autocomplete'},//自定义快捷键    hintOptions: {//自定义提示选项     tables: {      users: ['name', 'score', 'birthDate'],      countries: ['name', 'population', 'size']     }    }   })   //代码自动提示功能，记住使用cursorActivity事件不要使用change事件，这是一个坑，那样页面直接会卡死   editor.on('cursorActivity', function () {    editor.showHint()   })  } }</script><style>.codesql {  font-size: 11pt;  font-family: Consolas, Menlo, Monaco, Lucida Console, Liberation Mono, DejaVu Sans Mono, Bitstream Vera Sans Mono, Courier New, monospace, serif; }</style>
