Codemirror在Vue里面使用

codemirror

1.首先先安装好依赖包

npm install codemirror
yarn add codemirror

2.引入性对应的依赖包

import 'codemirror/theme/ambiance.css';
import 'codemirror/lib/codemirror.css';
import 'codemirror/addon/hint/show-hint.css';

const CodeMirror = require('codemirror');
require('codemirror/addon/edit/matchbrackets');
require('codemirror/addon/selection/active-line');
require('codemirror/mode/javascript/javascript');
require('codemirror/addon/hint/show-hint');
require('codemirror/keymap/sublime.js');
require('codemirror/addon/selection/active-line.js');
require('codemirror/addon/edit/matchbrackets.js');
require('codemirror/addon/display/autorefresh.js');

3.挂载textarea标签

<textarea ref="mycode" class="textarea" v-model="textarea">textarea>

4.实例CodeMirror

    mounted() {
     
		this.editorText = CodeMirror.fromTextArea(this.$refs.mycode, {
     
            mode: {
      name: 'javascript', globalVars: true },
            indentWithTabs: true,
            smartIndent: true,
            lineNumbers: true,
            matchBrackets: true,
            autoRefresh: 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'],
                },
            },
        });
        // 可选,挂载一下监听事项
        this.editorText.on('change', (cm: any) => {
     
            this.code = cm.getValue(); // 这里要用多一个载体去获取值,不然会重复赋值卡顿
        });
	}

刷新等问题

注意要注册一个刷新事件,方便调用

    refresh() {
     
        this.$nextTick(() => {
     
            this.editorText.refresh();
        });
    }

手动set值进去后要刷新

	setValue(value:string){
     
		this.cminstance.setValue(this.textarea);
        this.refresh();
	}

讲一下依赖包的引入

因为官方文档是全英文,而且写的十分零散

https://codemirror.net/

如果是更换语言的话可以在node_modules 里面找

对应修改位置

小聪也是刚刚开始接触这个插件,还在研究,之后有新的收获就会更新到这篇文章

更换主题

theme:更换主题,主题包在

更改引用的css样式

下面是例子:

material-darker

3024-day

剩下的下面就在theme里面同名更换就好了
