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   })  } })}
