微信小程序实战–集阅读与电影于一体的小程序项目(五)
21.电影页面数据绑定
movies.js
var app = getApp();
Page({
data: {
inTheaters: {},
comingSoon: {},
top250: {},
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options) {
var baseUrl = app.globalData.g_baseUrl;
var inTheatersUrl = baseUrl +"/v2/movie/in_theaters" + "?start=0&count=3";
var comingSoonUrl = baseUrl + "/v2/movie/coming_soon" + "?start=0&count=3";
var top250Url = baseUrl + "/v2/movie/top250" + "?start=0&count=3";
this.getMovieList(inTheatersUrl, "inTheaters")
this.getMovieList(comingSoonUrl, "comingSoon");
this.getMovieList(top250Url, "top250");
},
getMovieList(url, setKey) {
var that = this
wx.request({
url: url,
data: {},
method: 'GET',
header: {
'content-type': 'json' // 默认值 application/json
},
success: function (res) {
console.log(res)
that.processDoubanDate(res.data, setKey)
}
})
},
processDoubanDate: function (moviesDouban, setKey) {
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 = {
title: title,
average: subject.rating.average,
coverageUrl: subject.images.large,
movieId: subject.id
}
movies.push(temp)
}
var readyData = {};
readyData[setKey] = {
movies: movies
}
this.setData(readyData);
}
})
movies.wxml
<import src="movie-list/movie-list-template.wxml" />
<view class="container">
<view class="movies-template">
<template is="movielistTemplate" data="{{...inTheaters}}" />
</view>
<view class="movies-template">
<template is="movielistTemplate" data="{{...comingSoon}}" />
</view>
<view class="movies-template">
<template is="movielistTemplate" data="{{...top250}}" />
</view>
</view>
movie-list-template.wxml
<import src="../movie/movie-template.wxml" />
<template name="movielistTemplate">
<view class="movie-lsit-container">
<view class="inner-container">
<view class="movie-head">
<text class="slogan">正在热映</text>
<view class="more">
<text class="more-text">更多</text>
<image class="more-img" src="/images/icon/arrow-right.png"></image>
</view>
</view>
<view class="movies-container">
<block wx:for="{{movies}}" wx:for-item="movie">
<template is="movieTemplate" data="{{...movie}}" />
</block>
</view>
</view>
</view>
</template>
movie-template.wxml
<import src="../stars/stars-template.wxml" />
<template name="movieTemplate">
<view class="movie-container">

22.星星评分组件的实现
utils/util.js
function convertToStarArray(stars) {
var num = stars.toString().substring(0, 1)
var array = []
for (var i = 1; i <= 5; i++) {
if (i <= num) {
array.push(1)
}
else {
array.push(0)
}
}
return array;
}
module.exports = {
convertToStarArray: convertToStarArray,
};
movies.js
var util = require('../../utils/util.js')
var temp = {
stars: util.convertToStarArray(subject.rating.stars),
title: title,
average: subject.rating.average,
coverageUrl: subject.images.large,
movieId: subject.id,
}
movie.wxml
<import src="../stars/stars-template.wxml" />
<template name="movieTemplate">
<view class="movie-container">
<image class="movie-img" src='{{coverageUrl}}'></image>
<text class="movie-title">{{title}}</text>
<template is="starsTemplate" data="{{stars:stars,score:average}}" />
</view>
</template>
stars-template.wxml
<template name="starsTemplate">
<view class="stars-container">
<view class='stars'>
<block wx:for="{{stars}}" wx:for-item="i">
<image wx:if="{{i}}" src='/images/icon/star.png'></image>
<image wx:else src='/images/icon/none-star.png'></image>
</block>
</view>
<text class="star-score ">{{average}}</text>
</view>
</template>
23.更换电影分类标题
movies.js
this.getMovieList(inTheatersUrl, "inTheaters", "正在热映")
this.getMovieList(comingSoonUrl, "comingSoon", "即将上映");
this.getMovieList(top250Url, "top250", "豆瓣Top250");
getMovieList(url, setKey, categoryTitle) {
.
.
.
success: function (res) {
console.log(res)
that.processDoubanDate(res.data, setKey,categoryTitle)
}
})
},
processDoubanDate: function (moviesDouban, setKey,categoryTitle) {
.
.
.
readyData[setKey] = {
movies: movies,
categoryTitle: categoryTitle
}
this.setData(readyData);
}
movie-list-template.wxml
<text class="slogan">{{categoryTitle}}</text>
