由于微信小程序不能使用常規的圖文編輯器(比如百度的UEditor?)編輯新聞內容之類的，所以用vue寫了個針對小程序用的圖文編輯器。效果如下

?

多圖上傳圖片用到了??ajaxfileupload.js （不知道哪位仁兄寫的，拿來用了，很好用）

?

最終形成一串Json數據（轉成字符串，傳入后臺存入數據庫，小程序端用JSON.parse 轉成JSON ，按照后臺一樣的方式渲染即可【小程序端代碼還沒寫，后面再貼出來吧】）

json格式如

[{"mytype":1,"content":"測試數據\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"}]
