在vue中引入Kindeditor 修改图片上传逻辑

项目背景：vue element

1. 下载Kindeditor

npm i kindeditor

2.在项目的组件中封装components/kindeditor/index.vue
参考 官方文档 内置参数 也可根据项目要求进行定制化
下面代码对图片上传进行了定制 摒弃了自带的 弹窗的样式 直接现在文件的形式，把上传的文件 转化成base64进行存储 还可加一些校验！！！

<template>
  <div class="kindeditor">
    <textarea :id="id" name="content" v-model="outContent" placeholder="请输入"></textarea>
    <input
      @change="selectedFile"
      style="visibility: hidden;height:0;"
      type="file"
      name
      id="inputFile"
    />
  </div>
</template>

      let reader = new FileReader();
      reader.onload = function (evt) {
        let base64 = evt.target.result;
        cb(base64);
      };
      reader.readAsDataURL(file);
    }
  }
}
</script>

3. 对自定义的组件进行二次封装 views/components/kindeditor.vue
   通过自定义属性 对kindeditor组件进行样式上的自定义
   对组件返回的base64图片格式进行显示内容的拼接(注意直接修改prorps里text的值 是不生效的 父组件无法捕捉到值) 可参考文档

<template>
  <div id="app">
     <editor id="editor_id" :height="height" :width="width" :content.sync="text" :items="items"
            :afterChange="afterChange"
            @base64Flie="base64Flie"
            :loadStyleMode="false"
            @on-content-change="onContentChange"></editor>
    <!-- <div> editorTextCopy: {{ editorTextCopy }} </div> -->
 
  </div>
</template>
 
<script>
import editor from '@/components/kindeditor/index.vue'
 
export default {
  name: 'kindeditor',
  components: {
    editor
  },
  props:{
    height: {
      type: String,
      default: '500px'
    },
    width: {
      type: String,
      default: '700px'
    },
    text: {
      type: String,
      default: ''
    },

  },
  data () {
    return {
      editorText: '直接初始化值', // 双向同步的变量
      editorTextCopy: '' , // content-change 事件回掉改变的对象
      items: [
          'justifyleft', 'justifycenter', 'justifyright','justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript',
          'superscript',  'quickformat', 'selectall', 
          '|', 'fullscreen',
          'formatblock', 'fontname', 'fontsize', 
          '|', 'image', 'forecolor', 'hilitecolor', 'bold',
          'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', 
        ]
    }
  },
    methods: {
    onContentChange (val) {
      this.editorTextCopy = val;
      // window.console.log(this.editorTextCopy)
      this.$emit('update:text',this.editorTextCopy)
    },
    afterChange (e) {
      console.log(e)
    },
    base64Flie (base64) {
      this.text+=`<img src="${base64}" alt="">`
	  //注意
      this.$emit('update:text',this.text)
    }
  }
}
</script>

4. 在表单中使用 封装好的组件 kindeditor

<template>
  <div>
  <el-form ref="formData" :model="formData" label-width="100px" @submit.native.prevent>
  <el-row :gutter="3">
  <el-col :span="24">
  <el-form-item label="内容" prop="news_content" placeholder="内容" 
  :rules="[
  { required: true, message:'请输入'}
  ]">
  <kindeditor ref="news_content" :text.sync='formData.news_content' :width="'100%'"/>
  </el-form-item>
  </el-col>
  </el-row>
  </el-form>
  </div>
</template>
<script>
import kindeditor from './kindeditor.vue'
export default {
  props: {
    formData: {
      type: Object,
      default: () => {
        return {}
      }
    },
  },
  components:{
    kindeditor
  },
}

遇到的问题
1.打包上线 在点击上传图片时 会加载 refresh.png align_top.gif align_left.gif align_right.gif加载 错误的情况？
可通过修改pluginsPath的值
也可对 源码kindeditor-all.js 7221 7225 7226 7227进行注释 (在不影响需求的前提下 已解决问题优先)
碰到背景图片加载问题 修改打包文件目录
