JSON.parse（）无法正常工作

Question

in my server (python/django) side,

I have an array like this:

comments = [['rwerw', '215', '/news/215/'], ['wrwerwer', '215', '/news/215/'], ['Woinfoqf', '215', '/news/215/'], ['Good', '215', '/news/215/'], ["He's good", '215', '/news/215/']]

which I pass through to my ajax call as a string:

...

return JsonResponse({'comments': str(comments)})

I then use JSON.parse() to turn it back into an array object.

console.log(data.comments); // logs the json
var comments = JSON.parse(data.comments); // error 

However for some reason JSON.parse() is not working. When I use it I get the following error:

Error:

SyntaxError: JSON.parse: unexpected character at line 1 column 3 of the JSON data
.success 
n.Callbacks/i 
n.Callbacks/j.fireWith 
z 
.send/c/<

Any idea what the problem is?

您无需将注释列表转换为字符串-使其成为列表，并让JSONResponse正确地将整个字典转储为JSON：

return JsonResponse({'comments': comments})
