Code inside while loop not being executed JavaScript

阅读更多关于 Code inside while loop not being executed JavaScript

问题 I am working with this while loop and it is not working. I decided to use the Google Chrome debugger and I saw that the code inside is not being executed. All the time it checks the condition, starts the first line of the code inside, and goes back again to check the condition. It is a NodeJS server and I am using the Spotify API. app.get('/process', ensureAuthenticated, function (req, res) { let init_array = text.split(" "); let modtext = init_array; while (init_array.length != 0) {

Spotify Clear Playlist Drag and Drop

阅读更多关于 Spotify Clear Playlist Drag and Drop

问题 When you drag/drop an Artist into my app in the sidebar, I build a temporary playlist. Every time I drag a new Artist into my app, it builds a new list after the previous, WITHOUT clearing out the old one. (Note there is some code missing from here that is probably not needed). My question: how do I clear out or remove the current built playlist THEN build a new one, every time I drag/drop an Artist into my app? I suspect it would need to be called inside getRelated()? models.application

Custom Web Player for Spotify

问题 As far as I know, it is not possible to develop a Web app (outside spotify.com) providing a custom Web player which plays Spotify songs, am I right? The only option still seems to be the spotify play button, which is very limited though. I have just seen, however, this example 1) http://static.echonest.com/enspex/web/ChillRadio/ this one 2) http://lab.possan.se/thirtify/ and this one 3) https://developer.spotify.com/web-api/code-examples/ (see "Play something" snippet) that seems to use a

问题 I registered my app on Spotify. I made sure I had the URI added to my registered app. But still every time I run this code I keep getting the same error. I am also running this in the background so I know it's not that. What am I doing wrong? Also I tried switching /spotify with /provider_cb . var client_id = '<my_client_id>'; var redirectUri = chrome.identity.getRedirectURL() + "/spotify"; chrome.identity.launchWebAuthFlow({ "url": "https://accounts.spotify.com/authorize?client_id="+client

Spotify API Create Temp Playlist Not Loading

阅读更多关于 Spotify API Create Temp Playlist Not Loading

问题 I'm making a little app that displays a list of the top first song of an artist's related artists. When I try and load my app for the first time, it shows nothing. But, when I "Reload Application" everything seems to work. When I constantly start "Reloading" it keeps adding more of the same tracks to the list as well. How do I stop it from continually appending more tracks to the list as well as tighten up the code so that it works on load? require([ '$api/models', '$views/list#List', '$api

问题 I am trying to add a "save as playlist" button to my app API 1.0. Can someone help me figure out what is wrong here? var player_obj = models.Album.fromURI('spotify:album:7o7UHh5PfO1kY4YoxqrwN7'); player_obj.load('tracks').done(function(a){ var saved_playlist = new models.Playlist.create(player_obj.name); console.log(saved_playlist); a.tracks.snapshot().done(function(snapshot){ for (var i = 0, l = snapshot.length; i < l; i++) { var track = snapshot.get(i); saved_playlist.add(track); } }); });

Get play count of a track from Spotify API

阅读更多关于 Get play count of a track from Spotify API

问题 Is it possible to get the play count of a song (for the current user)? I only found Toplist and the Track class, but neither tells me how often a user listened to a song. 回答1: As far as I know there is no way to retrieve that data at the moment. 回答2: This is not possible through the Spotify API right now. The Last.fm API does offer information similar to this, as a potential work-around. 回答3: Marked as not right now on the Spotify support site. http://community.spotify.com/t5/Spotify-Ideas
