var app = getApp();//获取全局变量 app.js内部数据

Page({

data: {

},

onLoad: function (options) {

var inTheatersUrl = app.globalData.doubanBase +"/v2/movie/in_theaters"+"?start0&count=3";

var comingSoonUrl = app.globalData.doubanBase + "/v2/movie/coming_soon" + "?start0&count=3";

var top250Url = app.globalData.doubanBase + "/v2/movie/top250" + "?start0&count=3";

this.getMovieListData(inTheatersUrl,"inTheaters");

this.getMovieListData(comingSoonUrl,"comingSoon");

this.getMovieListData(top250Url,"top250")

},

getMovieListData: function (url, settedKey){

var that = this;

wx.request({

url: url,

data: {},

method: "GET",

header: {

"Content-Type": "json"

},

success(res) {

that.processDoubanData(res.data, settedKey)

}

})

},

// 处理电影返回的数据

processDoubanData: function (moviesDouban, settedKey){

var movies = [];

for(var idx in moviesDouban.subjects){

var subject = moviesDouban.subjects[idx];

var title = subject.title;

if(title.length>=6){

title = title.substring(0,6)+"..."

};

var temp = { //定义空对象 push到空数组

title: title,

average:subject.rating.average,//评分

coverageUrl:subject.images.large,//海报图片

movieId:subject.id

}

movies.push(temp)

}

var readyData = {};

readyData[settedKey] = {

movies:movies

}

this.setData(readyData)

console.log(readyData)

},

})

版本不会有问题的，贴代码看下。没报错多半是 你在wxml里的解析有问题。

  processDoubanData: function (moviesDouban, settedKey){
      var movies = [];
      for(var idx in moviesDouban.subjects){
        var subject = moviesDouban.subjects[idx];
        var title = subject.title;
        if(title.length>=6){
          title = title.substring(0,6)+"..."
        };
       var temp = { //定义空对象 push到空数组
         title: title,
        average:subject.rating.average,//评分
        coverageUrl:subject.images.large,//海报图片
        movieId:subject.id
       }
        movies.push(temp)
      }
      var readyData = {};
      readyData[settedKey] = {
        movies:movies
      }
      this.setData(readyData)
      console.log(readyData)
    },
