小程序 页面到详情的id传递

比如电影列表页跳转到电影详情页

在movie.js获取movieId;
 processDoubanData: function (moviesDouban, settedKey, categoryTitle) {
    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) + "...";
      }
      // [1,1,1,1,1] [1,1,1,0,0]
      var temp = {
        stars: util.convertToStarsArray(subject.rating.stars),
        title: title,
        average: subject.rating.average,
        coverageUrl: subject.images.large,
        movieId: subject.id
      }
      movies.push(temp)
    }
    var readyData = {};
    readyData[settedKey] = {
      categoryTitle: categoryTitle,
      movies: movies
    }
    this.setData(readyData);
  }

　　

在列表页模板上添加点击事件，绑定movieId，就获取了movieId,因为模板不能引入js，所以在列表页js地方写点击事件
<template name="movieTemplate">
    <view class="movie-container" catchtap="onMovieTap" data-movieId="{{movieId}}">
        <image class="movie-img" src="{{coverageUrl}}"></image>
        <text class="movie-title">{{title}}</text>
        <template is="starsTemplate" data="{{stars:stars, score: average}}" />
    </view>
</template>

 onMovieTap:function(event){
    var movieId = event.currentTarget.dataset.movieid;
    wx.navigateTo({
      url: "movie-detail/movie-detail?id="+movieId
    })
  },

在movie-detail.js
onLoad:function(options){
     var movieId = options.id;  

     var url = app.globalData.doubanBase +"/v2/movie/subject/" + movieId;

}
