最近公司项目有个需求是，回显微信聊天记录。
内容显示微信正常聊天对话

在此今天说下回显微信常用表情

产品的预期

我的预期

[微笑]微笑[撇嘴]撇嘴哈哈哈哈哈哈[微笑][撇嘴][色][发呆][得意][流泪][害羞][闭嘴][睡]

然后查看了下接口数据，我尼玛，后台抓取到的表情直接显示为文本类型？？？
奈何网上没有现成的插件可以直接回显，只好自己手动封装手写。
经过一番研究，特此记录下。

先说下大致思路：

需要一张完整表情包的精灵图，
用正则去匹配[***]这种文本
再写个json对照表，匹配到的再用json去匹配对应的style样式。
利用background-position读取每个表情包对应在精灵图上的位置。

先献上一张完整的表情精灵图。

js代码部分

function encodeEmoji(str){
  let pattern = /\[.*?\]/g;
  let unicodeStr = str.replace(pattern,function (match) {
    if(emojiJson[match]){
      return `<span class="small qqface ${emojiJson[match]}"></span>`
    }else return match
  })
  return unicodeStr
}

json对照表
