monaco-editor-vue的官方源码如下
index.js
import * as monaco from 'monaco-editor/esm/vs/editor/editor.api'; function noop() { } export { monaco }; export default { name: 'monacoeditor', props: { diffeditor: { type: boolean, default: false }, //是否使用diff模式 width: {type: [string, number], default: '100%'}, height: {type: [string, number], default: '100%'}, original: string, //只有在diff模式下有效 value: string, language: {type: string, default: 'javascript'}, theme: {type: string, default: 'vs'}, options: {type: object, default() {return {};}}, editormounted: {type: function, default: noop}, editorbeforemount: {type: function, default: noop} }, watch: { options: { deep: true, handler(options) { this.editor && this.editor.updateoptions(options); } }, value() { this.editor && this.value !== this._getvalue() && this._setvalue(this.value); }, language() { if(!this.editor) return; if(this.diffeditor){ //diff模式下更新language const { original, modified } = this.editor.getmodel(); monaco.editor.setmodellanguage(original, this.language); monaco.editor.setmodellanguage(modified, this.language); }else monaco.editor.setmodellanguage(this.editor.getmodel(), this.language); }, theme() { this.editor && monaco.editor.settheme(this.theme); }, style() { this.editor && this.$nexttick(() => { this.editor.layout(); }); } }, computed: { style() { return { width: !/^\d+$/.test(this.width) ? this.width : `${this.width}px`, height: !/^\d+$/.test(this.height) ? this.height : `${this.height}px` } } }, mounted () { this.initmonaco(); }, beforedestroy() { this.editor && this.editor.dispose(); }, render (h) { return ( <div class="monaco_editor_container" style={this.style}></div> ); }, methods: { initmonaco() { const { value, language, theme, options } = this; object.assign(options, this._editorbeforemount()); //编辑器初始化前 this.editor = monaco.editor[this.diffeditor ? 'creatediffeditor' : 'create'](this.$el, { value: value, language: language, theme: theme, ...options }); this.diffeditor && this._setmodel(this.value, this.original); this._editormounted(this.editor); //编辑器初始化后 }, _geteditor() { if(!this.editor) return null; return this.diffeditor ? this.editor.modifiededitor : this.editor; }, _setmodel(value, original) { //diff模式下设置model const { language } = this; const originalmodel = monaco.editor.createmodel(original, language); const modifiedmodel = monaco.editor.createmodel(value, language); this.editor.setmodel({ original: originalmodel, modified: modifiedmodel }); }, _setvalue(value) { let editor = this._geteditor(); if(editor) return editor.setvalue(value); }, _getvalue() { let editor = this._geteditor(); if(!editor) return ''; return editor.getvalue(); }, _editorbeforemount() { const options = this.editorbeforemount(monaco); return options || {}; }, _editormounted(editor) { this.editormounted(editor, monaco); if(this.diffeditor){ editor.ondidupdatediff((event) => { const value = this._getvalue(); this._emitchange(value, event); }); }else{ editor.ondidchangemodelcontent(event => { const value = this._getvalue(); this._emitchange(value, event); }); } }, _emitchange(value, event) { this.$emit('change', value, event); this.$emit('input', value); } } }
使用了vue想使用如上库中的_getvalue
方法怎么调呢?
定义ref=“”,使用this.$refs.exampleeditor._setvalue('')
参考如下代码
test.vue
<template> <div> <monacoeditor ref="exampleeditor" width="100%" height="300" theme="vs-dark" language="javascript" :options="options" @change="codeinput" /> </div> </template> <script> import monacoeditor from 'monaco-editor-vue' export default { components: { monacoeditor }, data() { return { } }, beforecreate() { }, mounted() { }, methods: { this.$refs.exampleeditor._setvalue('') } }
