「小程序JAVA实战」小程序的横向视频和页面拦截（59）

 

详情页面横竖屏的控制

如果视频的宽度大于高度，video的填充模式就修改为正常的情况。不进行填充

 

var videoUtils = require('../../utils/videoUtils.js')
const app = getApp()
Page({

  data: {
    cover:'cover',
    videoContext:"",
    videoInfo:{},
    videId:'',
    src:''
  },


  showSearch:function(){
    wx.navigateTo({
      url: '../videoSearch/videoSearch',
    })
  },
  onLoad:function(params){
    var me = this;
    me.videoContext = wx.createVideoContext('myVideo', me);
    var videoInfo = JSON.parse(params.videoInfo);
    var videoWidth = videoInfo.videoWidth;
    var videoHeight = videoInfo.videoHeight;
    var cover = 'cover';
    if (videoWidth > videoHeight){
      cover = '';
    }
    me.setData({
      videId: videoInfo.id,
      src: app.serverUrl + videoInfo.videoPath,
      videoInfo: videoInfo,
      cover: cover
    })


  },
  showIndex:function(){
    wx.redirectTo({
      url: '../index/index',
    })
  },

  onShow:function(){
    var me = this;
    me.videoContext.play();
  },
  onHide:function(){
    var me = this;
    me.videoContext.pause();
  },
  upload:function(){
    videoUtils.uploadVideo();
  },
  showMine: function () {
    var me = this;
    var userInfo = app.getGlobalUserInfo();
    if (userInfo.id == '' || userInfo.id == undefined){
      wx.navigateTo({
        url: '../userLogin/userLogin',
      })
    }else{
      wx.navigateTo({
        url: '../mine/mine',
      })
    }


  },
})

详情跳转到个人页面

判断缓存中是否存在用户信息，存在跳转到个人信息页面，不存在，跳转到登录页面

PS：小程序一般的开发思路就是尽量前端能办的少麻烦后端，减少交互。这样用户体验就上去了。
