nuxt中富文本编辑器【vue-quill-editor】的集成

百度搜一下“VUE 富文本编辑器”,五花八门,N多种,推荐比较多的是集成百度的UEditor,然后是vue-quill-editor。后者是专门为vue提供的,结合起来更顺手。试了试UEditor,然后放弃了,虽然功能丰富,但是确实略麻烦。vue-quill-editor简单轻巧又开源,可自己随意订制,因此选了后者。下面简单说一下怎么使用。

先上最终效果,如图:

1、组件编写

1.Quilleditor组件
在components/common下创建Quilleditor.vue,主要代码如下:

<template>
  <div>
    <quill-editor v-model="content"
                  ref="myTextEditor"
                  :options="editorOption"
                  @change="onChange"
                  style="width: 80%;height: 500px;padding-left: 10%;padding-right: 10%"
    >
      <div id="toolbar" slot="toolbar">
        <span class="ql-formats"><button type="button" class="ql-bold"></button></span>

            this.content = newVal
          }
        }
      }
    }
  }
</script>

2.CropUpload组件--图片裁剪

<template>
  <vue-crop @crop-upload-success="uploadSuccess"
            v-model="show"
            :width="width"
            :height="height"
            :url="uploadUrl"
            :field="fileName"
            img-format="png"></vue-crop>
</template>

<script>
  import VueCrop from 'vue-image-crop-upload'

  export default {
    props: {
      value: {
        type: Boolean
      },
      width: {
        type: Number,
        default: 200
      },
      height: {
        type: Number,
        default: 200
      },
      uploadUrl: {
        type: String
      },
      fileName: {
        type: String
      },
    },
    data () {
      return {
        show: false,
      }
    },
    mounted () {
      this.show = this.value
    },
    components: {
      VueCrop
    },
    methods: {
      uploadSuccess (res, field) {
        this.$emit('uploadSuccess', res)
      },
    },
    watch: {
      value (newv) {
        this.show = newv
      },
      show (newv) {
        if (!this.show){
          this.$emit('input', false)
        }
      }
    }
  }
</script>
<style>
</style>

2、插件js编写

  • 在plugins下创建nuxt-quill-plugin.js
import Vue from 'vue'
import VueQuillEditor from 'vue-quill-editor'
Vue.use(VueQuillEditor)

if (process.browser) {
  const VueQuillEditor = require('vue-quill-editor/ssr')
  Vue.use(VueQuillEditor)
}
  • 然后在nuxt.config.js中引入该插件
  plugins: ['~plugins/element-ui',
    {src: '~plugins/nuxt-quill-plugin.js', ssr: false}]

所有配置完以后,你会发现出现的效果有可能如下:

img_ea24b49d5bb4899868f714bf23437ac7.png
window is not defined

这坑爹玩意,是因为nuxt默认首页服务端渲染,其他页面客户端渲染,而window对象只在客户端存在,因此最好不要让带富文本的页面出现在首页使用。当然这不是终极解决办法,不过vue-quill-editor同样支持服务端渲染,稍候再做研究。
