我把文本框封装成了一个组件，方便项目调用。

<!-- editor.vue -->
<template>
    <div>
        <div ref="editor" style="text-align:left">
        </div>
    </div>
</template>

<script>
    import E from 'wangeditor'
    export default {
      name: 'editor',
      data () {
        return {
          editor: null,
        }
      },
      props: {
        value: {
          default: ""
        }
      },
      mounted() {;
        this.editor = new E(this.$refs.editor)
        this.editor.customConfig.onchange = (html) => { // 获取内容
          this.$emit("input", html);
        }
        this.editor.create();
        this.editor.txt.html(this.value); // 设置内容
      }
    }
</script>

<style scoped>
</style>

在别的vue文件中引用：

<!--  template -->
<Editor v-model="content"/>
// js 
components: {
    Editor: resolve => resolve(require('./component/editor/editor.vue'))          
},
