求解：我这排序好像没反应

var app = getApp()

Page({

data: {

tabTxt: ['品牌', '价格', '销量'],//分类

tab: [true, true, true],

pinpaiList: [{ 'id': '1', 'title': '万科' }, { 'id': '1', 'title': '碧桂园' }],

pinpai_id: 0,//品牌

pinpai_txt: '',

jiage_id: 0,//价格

jiage_txt: '',

xiaoliang_id: 0,//销量

xiaoliang_txt: '',

},

onLoad: function (options) {

var that = this

wx.request({

url: 'http://192.168.1.103/json/shuju.json',

method: 'get',

headers: {

'Content-Type': 'json'

},

success: function (res) {

console.log(res);

that.setData({

dataList: res.data

})

}

})

},

// 选项卡

filterTab: function (e) {

var data = [true, true, true], index = e.currentTarget.dataset.index;

data[index] = !this.data.tab[index];

this.setData({

tab: data

})

},

//筛选项点击操作

filter: function (e) {

var self = this,

id = e.currentTarget.dataset.id,

txt = e.currentTarget.dataset.txt,

tabTxt = this.data.tabTxt;

switch (e.currentTarget.dataset.index) {

case '0':

tabTxt[0] = txt;

self.setData({

tab: [true, true, true],

tabTxt: tabTxt,

pinpai_id: id,

pinpai_txt: txt

});

break;

case '1':

tabTxt[1] = txt;

self.setData({

tabTxt: tabTxt,

jiage_txt: txt

});

break;

case '2':

break;

}

//数据筛选

self.getDataList();

},

//加载数据

getDataList: function () {

//调用数据接口，获取数据

var that = this

wx.request({
