vue使用引用库中的方法附源码,博智网带你了解详细信息。

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 : `${this.height}px`      }    }  },  mounted () {    this.initMonaco();  },  beforeDestroy() {    this.editor && this.editor.dispose();  },  render (h) {    return (      <p class="monaco_editor_container"     );  },  methods: {    initMonaco() {      const { value, language, theme, options } = this;      Object.assign(options, this._editorBeforeMount());      //编辑器初始化前      this.editor = monaco.editor[this.diffEditor ? 'createDiffEditor' : 'create'](this.$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>  <p>    <MonacoEditor ref="exampleEditor" width="100%" height="300" theme="vs-dark" language="javascript" :options="options" @change="codeInput" />  </p></template><script>import MonacoEditor from 'monaco-editor-vue'export default {  components: {    MonacoEditor  },  data() {    return {    }  },  beforeCreate() {  },  mounted() {  },  methods: {    this.$refs.exampleEditor._setValue('')  }}
