vue+element-ui实现富文本(含有图片粘贴拖拽上传)

Just For Share | 仅仅分享

首先需要安装

• cnpm i vue-quill-editor -D 富文本编辑器
• cnpm install quill-image-resize-module --save 照片缩小放大
• cnpm install --save quill-image-drop-module 照片拖拽
• cnpm install --save quill-image-paste-module 照片拖拽

特别注意会出现以下错误

安装好上述之后会出现下面错误

Cannot read property ‘imports’ of undefined"

解决

找到webpack.base.conf.js，然后添加下面代码
const webpack = require('webpack')
 plugins: [
new webpack.ProvidePlugin({
  'window.Quill': 'quill/dist/quill.js',
  'Quill': 'quill/dist/quill.js'
})
]

整体代码

包含以下的功能点

支持拖拽图片上传

image: function image() {
var self = this;
var fileInput = this.container.querySelector('input.ql-image[type=file]');
if (fileInput === null) {
  fileInput = document.createElement('input');
  fileInput.setAttribute('type', 'file');
  // 设置图片参数名
  if (uploadConfig.filename) {
    fileInput.setAttribute('name', uploadConfig.filename);
  }
  // 可设置上传图片的格式
  fileInput.setAttribute('accept', uploadConfig.accept);
  fileInput.classList.add('ql-image');
  let name = ''
  // 监听选择文件
  fileInput.addEventListener('change', function () {
    // 创建formData
    var formData = new FormData();
    name = fileInput.files[0].name
    formData.append("filename", name);
    formData.append("file", fileInput.files[0]);
    formData.append("path", "advice");
    // 图片上传
    var xhr = new XMLHttpRequest();
    xhr.open(uploadConfig.methods, uploadConfig.action, true);
    // 上传数据成功，会触发
    xhr.onload = function (e) {
      if (xhr.status === 200) {
        var res = JSON.parse(xhr.responseText);
        let length = self.quill.getSelection(true).index;
        //这里很重要，你图片上传成功后，img的src需要在这里添加，res.path就是你服务器返回的图片链接。
        let path = '/api/oa/loadFile?path=advice&filename=' + name
        self.quill.insertEmbed(length, 'image', path);
        self.quill.setSelection(length + 1)
      }
      fileInput.value = ''
    };
    // 开始上传数据
    xhr.upload.onloadstart = function (e) {
      fileInput.value = ''
    };
    // 当发生网络异常的时候会触发，如果上传数据的过程还未结束
    xhr.upload.onerror = function (e) {
    };
    // 上传数据完成（成功或者失败）时会触发
    xhr.upload.onloadend = function (e) {
      // console.log('上传结束')
    };
    xhr.send(formData)
  });
  this.container.appendChild(fileInput);
}
fileInput.click();

}

支持粘贴图片上传

  ImageExtend: {
loading: true,
name: 'file',
action: '/api/oa/uploadFile',
change: (xhr, FormData) => {
  var uuid = "cms"+this.guid();
  FormData.append('path', "advice")
  FormData.append('filename', uuid)
  this.fileName = uuid
},
response: (res) => {
  console.log(res, 'response')
  return "/api/oa/loadFile?path=advice&filename="+this.fileName
}
}

支持方法和缩小
