vue element el-dialog中引入ueditor

今天引入ueditor遇到报错：Uncaught TypeError: Cannot read property ‘offsetWidth‘ of null

原因是dialog还没初始化完成，导致获取不到offsetWidth，解决方案如下：

<template>

  <el-dialog
    :title="!dataForm.id ? '新增' : '修改'"
    top="5px"
    :close-on-click-modal="false"
    :visible.sync="visible">
    <el-form :model="dataForm" :rules="dataRule" ref="dataForm" @keyup.enter.native="dataFormSubmit()" label-width="80px">

    <el-form-item label="标题" prop="title">
      <el-input v-model="dataForm.title" placeholder="标题"></el-input>
    </el-form-item>
    <el-form-item label="内容" prop="content">

      <script :id="ueId" class="ueditor-box" type="text/plain" style="width: 500px; height: 260px;"></script>

    </el-form-item>
 
    </el-form>
    <span slot="footer" class="dialog-footer">
      <el-button @click="visible = false">取消</el-button>
      <el-button type="primary" @click="dataFormSubmit()">确定</el-button>
    </span>
  </el-dialog>
</template>

<script>
  import ueditor from 'ueditor'
  export default {
    data () {
      return {
        visible: false,
        dataForm: {
          id: 0,
          title: '',
          content: ''
        },
        dataRule: {
          title: [
            { required: true, message: '标题不能为空', trigger: 'blur' }
          ]
  
        },
        ue: null,
        ueId: `J_ueditorBox_${new Date().getTime()}`,
      }
    },
    methods: {
      //初始化
      init (id) {
        this.dataForm.id = id || 0
        this.visible = true
        this.$nextTick(() => {
          this.$refs['dataForm'].resetFields()
         //解决办法：等dialog渲染完成再获取editor
          this.ue = ueditor.getEditor(this.ueId, {
            // serverUrl: '', // 服务器统一请求接口路径
            zIndex: 3000
          })
          if (this.dataForm.id) {
            this.$http({
              url: this.$http.adornUrl(`/sys/sysnotify/info/${this.dataForm.id}`),
              method: 'get',
              params: this.$http.adornParams()
            }).then(({data}) => {
              if (data && data.code === 0) {
                this.dataForm.title = data.sysNotify.title
                this.dataForm.content = data.sysNotify.content
                //ueditor回显
                ue.addListener('ready',function () {
                  ue.execCommand('insertHtml',data.sysNotify.content);
                });
              }
            })
          }
      
        })
      },
      // 表单提交
      dataFormSubmit () {
        this.$refs['dataForm'].validate((valid) => {
          if (valid) {
            this.$http({
              url: this.$http.adornUrl(`/sys/sysnotify/${!this.dataForm.id ? 'save' : 'update'}`),
              method: 'post',
              data: this.$http.adornData({
                'id': this.dataForm.id || undefined,
                'title': this.dataForm.title,
                'content': this.ue.getContent()
              })
            }).then(({data}) => {
              if (data && data.code === 0) {
                this.$message({
                  message: '操作成功',
                  type: 'success',
                  duration: 1500,
                  onClose: () => {
                    this.visible = false
                    this.$emit('refreshDataList')
                  }
                })
              } else {
                this.$message.error(data.msg)
              }
            })
          }
        })
      }
    }
  }
</script>

ueditor是通过插件方式引入
