Convert Array als String-Array in JavaScript

Question

Ich habe eine string Variable songs, mit folgendem Inhalt von einem Streaming-Protokolldatei:

[{'url':'https://open.spotify.com/track/0TLAptKgYxe7F0KewWH6X6','title':'I Need A Forest Fire','album':'The Colour In Anything','artist':'James Blake, Bon Iver','coverUrl':'https://i.scdn.co/image/7b8f132a8a91d46cce43b42bd0916f16708c8358','date':'May 21, 2016 at 04:41PM'}, 
{'url':'https://open.spotify.com/track/3cBV8V9zlYNraydyF8NpBY','title':'Dress','album':'Sylvan Esso','artist':'Sylvan Esso','coverUrl':'https://i.scdn.co/image/d64189ee29314326a188f1a334dfd20c085dfb7e','date':'May 22, 2016 at 06:53PM'}, 
{'url':'https://open.spotify.com/track/6W3CjUdc26sI1Y7cmelM5A','title':'Stutter','album':'Good Future','artist':'EMEFE','coverUrl':'https://i.scdn.co/image/10669383f3ca6f90b6692e2da9b6601f020078ff','date':'May 23, 2016 at 12:57AM'}, 
{'url':'https://open.spotify.com/track/1GxNPd5r7D1zChEMuMhue0','title':'Only','album':'Dawn','artist':'RY X','coverUrl':'https://i.scdn.co/image/281bc0be895562e7146b361931330ec5a586d1ba','date':'May 24, 2016 at 01:55AM'}] 

Wie kann ich wandeln es in einem tatsächlichen Array in JavaScript? Ich habe versucht JSON.parse(), aber es ist fehlgeschlagen. Liegt es daran, dass die Werte in einfachen Anführungszeichen stehen und nicht in Anführungszeichen? (Ich habe keine Kontrolle über die Streaming-Datendatei.)

Answer 1

Sie verwenden können eval()

var songs = `[{'url':'https://open.spotify.com/track/0TLAptKgYxe7F0KewWH6X6','title':'I Need A Forest Fire','album':'The Colour In Anything','artist':'James Blake, Bon Iver','coverUrl':'https://i.scdn.co/image/7b8f132a8a91d46cce43b42bd0916f16708c8358','date':'May 21, 2016 at 04:41PM'}, 
 
{'url':'https://open.spotify.com/track/3cBV8V9zlYNraydyF8NpBY','title':'Dress','album':'Sylvan Esso','artist':'Sylvan Esso','coverUrl':'https://i.scdn.co/image/d64189ee29314326a188f1a334dfd20c085dfb7e','date':'May 22, 2016 at 06:53PM'}, 
 
{'url':'https://open.spotify.com/track/6W3CjUdc26sI1Y7cmelM5A','title':'Stutter','album':'Good Future','artist':'EMEFE','coverUrl':'https://i.scdn.co/image/10669383f3ca6f90b6692e2da9b6601f020078ff','date':'May 23, 2016 at 12:57AM'}, 
 
{'url':'https://open.spotify.com/track/1GxNPd5r7D1zChEMuMhue0','title':'Only','album':'Dawn','artist':'RY X','coverUrl':'https://i.scdn.co/image/281bc0be895562e7146b361931330ec5a586d1ba','date':'May 24, 2016 at 01:55AM'}]`; 
 

 
var res = eval(songs); 
 

 
console.log(res);

Siehe die folgende Frage: Why is using the JavaScript eval function a bad idea?

Oder ersetzen Sie alle einzelnen Anführungszeichen durch doppelte und dann parsen es JSON.parse()

var songs = `[{'url':'https://open.spotify.com/track/0TLAptKgYxe7F0KewWH6X6','title':'I Need A Forest Fire','album':'The Colour In Anything','artist':'James Blake, Bon Iver','coverUrl':'https://i.scdn.co/image/7b8f132a8a91d46cce43b42bd0916f16708c8358','date':'May 21, 2016 at 04:41PM'}, 
 
{'url':'https://open.spotify.com/track/3cBV8V9zlYNraydyF8NpBY','title':'Dress','album':'Sylvan Esso','artist':'Sylvan Esso','coverUrl':'https://i.scdn.co/image/d64189ee29314326a188f1a334dfd20c085dfb7e','date':'May 22, 2016 at 06:53PM'},

var res = JSON.parse(songs.replace(/'/g, '"')); 
 

 
console.log(res);

Answer 2

mit Hilfe von Javascript eval wird die Arbeit machen.

var str = "[{'url':'https://open.spotify.com/track/0TLAptKgYxe7F0KewWH6X6','title':'I Need A Forest Fire','album':'The Colour In Anything','artist':'James Blake, Bon Iver','coverUrl':'https://i.scdn.co/image/7b8f132a8a91d46cce43b42bd0916f16708c8358','date':'May 21, 2016 at 04:41PM'},{'url':'https://open.spotify.com/track/3cBV8V9zlYNraydyF8NpBY','title':'Dress','album':'Sylvan Esso','artist':'Sylvan Esso','coverUrl':'https://i.scdn.co/image/d64189ee29314326a188f1a334dfd20c085dfb7e','date':'May 22, 2016 at 06:53PM'},{'url':'https://open.spotify.com/track/6W3CjUdc26sI1Y7cmelM5A','title':'Stutter','album':'Good Future','artist':'EMEFE','coverUrl':'https://i.scdn.co/image/10669383f3ca6f90b6692e2da9b6601f020078ff','date':'May 23, 2016 at 12:57AM'},{'url':'https://open.spotify.com/track/1GxNPd5r7D1zChEMuMhue0','title':'Only','album':'Dawn','artist':'RY X','coverUrl':'https://i.scdn.co/image/281bc0be895562e7146b361931330ec5a586d1ba','date':'May 24, 2016 at 01:55AM'}]" 
eval(str) 

Eine andere Art und Weise tun

var f = new Function('return ' + str); 
var arr = f(); 

du wie diese SO thread für den Unterschied zwischen eval und new Function überprüfen

Answer 3

Ersetzen Sie alle Apostrophe mit Doppel und verwenden JSON.parse() :

var str = "[{'url':'https://open.spotify.com/track/0TLAptKgYxe7F0KewWH6X6','title':'I Need A Forest \ Fire','album':'The Colour In Anything','artist':'James Blake, Bon\ Iver','coverUrl':'https://i.scdn.co/image/7b8f132a8a91d46cce43b42bd0916f16708c8358','date':'May 21, 2016 at 04:41PM'}, \ 
{'url':'https://open.spotify.com/track/3cBV8V9zlYNraydyF8NpBY','title':'Dress','album':'Sylvan Esso','artist':'Sylvan Esso','coverUrl':'https://i.scdn.co/image/d64189ee29314326a188f1a334dfd20c085dfb7e','date':'May 22, 2016 at 06:53PM'}, \ 
{'url':'https://open.spotify.com/track/6W3CjUdc26sI1Y7cmelM5A','title':'Stutter','album':'Good Future','artist':'EMEFE','coverUrl':'https://i.scdn.co/image/10669383f3ca6f90b6692e2da9b6601f020078ff','date':'May 23, 2016 at 12:57AM'}, \ 
{'url':'https://open.spotify.com/track/1GxNPd5r7D1zChEMuMhue0','title':'Only','album':'Dawn','artist':'RY X','coverUrl':'https://i.scdn.co/image/281bc0be895562e7146b361931330ec5a586d1ba','date':'May 24, 2016 at 01:55AM'}]"; 

str = str.replace(/'/g, '"'); 
var strJson = JSON.parse(str); 
console.log(strJson);
