vue使用引用库 vue使用引用库中的方法附源码
后青春的晴诗 人气:0想了解vue使用引用库中的方法附源码的相关内容吗,后青春的晴诗在本文为您仔细讲解vue使用引用库的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:vue使用引用库,vue引用库,下面大家一起来学习吧。
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('') } }
