小程序 editor（富文本编辑器的使用）

wxml的引用：

<editor id="editora" read-only="true" bindready="ready"></editor>

id：命名，为了在js中使用该组件
read-only：设置编辑器是否为只读
bindready：编辑器初始化完成时触发
editor官方链接

js事件：

ready: function () {
    let editor = null
    const query = wx.createSelectorQuery()
    query.select('#editora').context((res) => {
      editor = res.context
    }).exec()
    APP.request.get(APP.api.business, {
      m: "getNewsById",
      id: this.options.id,
    }, (data) => {
      this.setData({
        detail: data
      })

      editor.setContents({
        html: data.content
      })
    });
  },

js思路解析：

1. 设置一个空对象，用于后续存储；
2. 返回一个 SelectorQuery对象实例；
3. 获取对象的内容，填充到之前的空对象中；
4. 通过接口获取数据（可忽略）；
5. setContents：初始化编辑器内容，html和delta同时存在时仅delta生效
