基于Vue實現(xiàn)微信小程序的圖文編輯器
由于微信小程序不能使用常規(guī)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(shù)據(jù)(轉成字符串,傳入后臺存入數(shù)據(jù)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(shù)據(jù)\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"}]
