由于微信小程序不能使用常规的图文编辑器(比如百度的UEditor )编辑新闻内容之类的，所以用vue写了个针对小程序用的图文编辑器。效果如下
多图上传图片用到了 ajaxfileupload.js （不知道哪位仁兄写的，拿来用了，很好用）
最终形成一串Json数据（转成字符串，传入后台存入数据库，小程序端用JSON.parse 转成JSON ，按照后台一样的方式渲染即可【小程序端代码还没写，后面再贴出来吧】）
json格式如
[{"mytype":1,"content":"测试数据\n\n11111\n\n","font":{"size":0,"weight":1,"del":1,"line":0,"center":1,"color":"#ED1C24","bgcolor":"#fff","showcolor":0}},{"mytype":3,"content":""},{"mytype":2,"content":"/upload/dyProductImgs/20180725/9841925131090216.jpg_E500_100.jpg","loading":1,"groupid":"627459ec-d372-e372-218e-b93b83cb2d02"},{"mytype":2,"content":"/upload/dyProductImgs/20180725/1574162212592205.jpg_E500_100.jpg","loading":1,"groupid":"627459ec-d372-e372-218e-b93b83cb2d02"},{"mytype":2,"content":"/upload/dyProductImgs/20180725/8745023656415428.jpg_E500_100.jpg","loading":1,"groupid":"627459ec-d372-e372-218e-b93b83cb2d02"},{"mytype":2,"content":"/upload/dyProductImgs/20180725/7027501123579481.jpg_E500_100.jpg","loading":1,"groupid":"627459ec-d372-e372-218e-b93b83cb2d02"}]
