播放不了
改成不加引号的 this.data.local_database[0].music.url 这个不行 还是无法播放
var post_play = require('../../../data/post-data.js');
var app = getApp();
// 获取本地数据
Page({
data: {
},
onLoad: function (option) {
var postId = option.id;
// 从yuyin传递来id值
this.data.currentPostId = postId;
var xiangqing = post_play.post_list[postId];
// 得到id文章值
this.setData({
xiangqing: xiangqing
});
},
onMusicTap: function (event) {
var currentPostId = this.data.currentPostId;
var postData = post_play.post_list[currentPostId];
var isPlayingMusic = this.data.isPlayingMusic;
if (isPlayingMusic) {
wx.pauseBackgroundAudio();
this.setData({
isPlayingMusic: false
})
app.globalData.g_isPlayingMusic = false;
}
else {
wx.playBackgroundAudio({
dataUrl: postData.music.url,
title: postData.music.title,
coverImgUrl: postData.music.coverImg,
})
this.setData({
isPlayingMusic: true
})
app.globalData.g_currentMusicPostId = this.data.currentPostId;
app.globalData.g_isPlayingMusic = true;
}
}
})
当我把
onMusicTap: function (event) {
var currentPostId = this.data.currentPostId;
var postData = post_play.post_list[currentPostId];
中的xiangqing改成postData后 问题就解决了
可以播放吗？
谢谢
改成不加引号的 this.data.local_database[0].music.url 试试
如果dataUrl没有引号 就会报错
报错如下
thirdScriptError

是一个地址
dataUrl是一个字符串？
