微信小程序实现留言功能

主要的wxss代码(用于点赞的展示,实现小手、空心小手)

.nodzimg2 {
 background: url(空心);
 background-size: 100%;
}
 
.dzimg2 {
 background: url(实心);
 background-size: 100%;
}

js

var liuynfun = function (that) {
 wx.request({
  url: getApp().data.host + '...',
  method: "POST",
  data: {
   "column": "Routine",
   "row_id": that.data.url
  },
  header: {
   'content-type': 'application/x-www-form-urlencoded'
  },
  success: function (res) {
   if (res.data.list != "") {
    //第一行留言
    for (var i in res.data.list) {
     res.data.list[i].lldzView = false;
     if (res.data.list[i].like_user != null) {
      if (res.data.list[i].like_user.indexOf(wx.getStorageSync('user_id')) != "-1") {
       res.data.list[i].lldzView = true
      }
     }
     // 第二行留言
     if (res.data.list[i]._child){
      for (var j in res.data.list[i]._child){
       res.data.list[i]._child[j].cnmView=false
       if (res.data.list[i]._child[j].like_user != null) {
        if (res.data.list[i]._child[j].like_user.indexOf(wx.getStorageSync('user_id')) != "-1") {
         res.data.list[i]._child[j].cnmView = true
        }
       }
      }
     }
    }
 
   }
   that.setData({
    yanlist: res.data
   })
  }
 })
