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

基于Vue实现微信小程序的图文编辑器

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"}] 

 html代码

<div class="editor-box vue-container">
 <div class="vuefor" v-for="i in editorData.length+1" v-on:click="hidecolorbox(i-1)">
  <div class="tool-box">

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
