21.影片页面数据绑定

movies.js

var app = getApp();
Page({
  data: {
    inTheaters: {},
    comingSoon: {},
    top250: {},

      success: function (res) {

      var temp = {

      movies.push(temp)

23.更动电影分类标题

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);

  }

功能传递的四个参数到了那些分界面了

Page({ /** * 页面的初始数据 */ data: { name: '王小婷', age: '22' }, buttonListener: function () { var that = this wx.navigateTo({ url: '/pages/navigator/navigator?nameData='   that.data.name   '&ageData='   that.data.age }) }})
Page({ data: { }, //事件处理函数 bindViewTap: function() { wx.navigateTo({ url: '../navigator/navigator?title=我来到了这个神奇的界面并且认识了一个萌妹子&&what=wangting' // url: '../logs/logs' }) }, //事件处理函数 onLoad: function

效果:

<view><text>我的姓名是:{{name}}</text></view><view><text>我的年龄是:{{age}}</text></view>

navigator.wxml

navigator.wxml

要把参数字传送递给navigator分界面

只带叁个参数跳转:

index.wxml

<view> <text>姓名:{{name}}</text></view><button bindtap='buttonListener'>携参数跳转界面</button>

index.js

Page({ data: { name: '王小婷' }, buttonListener: function () { var that = this wx.navigateTo({ url: '/pages/navigator/navigator?nameData='   that.data.name }) }})

navigator.wxml

<view><text>我的姓名是:{{name}}</text></view>

navigator.js

Page({ data: { name: null }, onLoad: function  { var that = this that.setData({ name: options.nameData, }) }})

原来的作品我:祈澈姑娘。 技巧博客:

index.wxml

<view> <text>姓名:{{name}}</text></view><view> <text>年龄:{{age}}</text></view><button bindtap='buttonListener'>携参数跳转界面</button>

Page({ data: { }, //事件处理函数 onLoad: function

通过js里面包车型地铁绑定的函数事件来跳转index.wxml

<view bindtap="bindViewTap" > 我要绑定事件带着两个参数跳转界面</view>

再来三个demo:便于通晓和施行index.wxml

Page({ /** * 页面的初始数据 */ data: { name: null, age: null }, /** * 生命周期函数--监听页面加载 */ onLoad: function  { var that = this that.setData({ name: options.nameData, age: options.ageData }) }})

Wechat小程序 页面跳转 传递参数的这几个知识点大家在开荒进程之中会平常遭遇,记录一下,尽管很简短,不过对于刚同志刚接触的人的话,看文书档案不比看demo来的快和方便。先看一下合法给出的文书档案:
