thirdScriptError:Cannot read property ‘songlist’ of undefined;at api request success callback function
TypeError: Cannot read property ‘songlist’ of undefined.

这是我练习的list.js源代码：

// pages/list/list.js

var config = require('../../config.js');

var formatSeconds = function(value) {

var time = parseFloat(value);

var m = Math.floor(time / 60);

var s = time - m * 60;

return [m, s].map(formatNumber).join(':');

function FormatNumber(n) {

n = n.toString()

return n[1] ? n : '0' + n

}

Page({

data: {

board: '',

songlist: [],

loading: false,

},

onLoad: function(options) {

var self = this;

var topid = options.type;

this.setData({

loading: true

})

wx: wx.request({

url: config.config.hotUrl,

data: {

topid: topid

},

success: function(e) {

//var songlist=songlist;

//var self = this;

if (e.statusCode == 200) {

var songlist = e.data.showapi_res_body_pagebean.songlist;

for (var i = 0; i < songlist.length; i++) {

songlist[i].seconds = formatSeconds(songlist[i].seconds);

}

self.setData({ //估计是这里出bug

board: e.data.showapi_res_body_pagebean.songlist[0].albumpic_big,

songlist: songlist,/** 定位？**/

loading: false

});

wx.setStorageSync('songlist', songlist);

}

});

}

})
