用于微信小程序的图文编辑器

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"}]

 现在增加上微信小程序端的代码 

js:（对从接口返回的数据进行处理）

 //将后台返回的数据转成JSON格式。
            ProductDesc = JSON.parse(ProductDesc);
            if (ProductDesc)
              for (var p = 0; p < ProductDesc.length; p++) {
                ProductDesc[p].style = "";
                //如果是文字类型，需要设置样式
                if (ProductDesc[p].mytype == 1 && ProductDesc[p].font) {
                  if (ProductDesc[p].font.del == 1) ProductDesc[p].style += "text-decoration:line-through;"
                  if (ProductDesc[p].font.line == 1) ProductDesc[p].style += "text-decoration:underline;"
                  if (ProductDesc[p].font.center == 1) ProductDesc[p].style += "text-align:center;"
                  if (ProductDesc[p].font.weight == 1) ProductDesc[p].style += "font-weight:bold;"
                  if (ProductDesc[p].font.color) ProductDesc[p].style += "color:" + ProductDesc[p].font.color + ';'
                  if (ProductDesc[p].font.size) ProductDesc[p].style += "font-size:" + (30 + 6 * ProductDesc[p].font.size) + 'rpx'
                }
              }

　　view：（按照预定格式展现视图）

 
          
            
              {{item.content}}
