Javascript无法解析JSON字符串

Question

I was trying to parse this JSON string:

{"query": "my schedule today","type": "timeline","title": "Today events:","time":["2015-07-06\\n20:30:00"],"summary":["Weekly meeting + Show & Tell (Hangout)"],"description":["Weekly Bullets (20 minutes): "]}

This is a valid JSON (checked on jsonformatter.curiousconcept.com). However, I received erorr:

SyntaxError: Unexpected token

in (file angular.js):

function fromJson(json) {
    return isString(json)
        ? JSON.parse(json)
        : json;
}

Anyone has ideas?

Answer 1

The problem is the \\n in the text, you need to escape it to \\\\n

 var json = '{"query": "my schedule today","type": "timeline","title": "Today events:","time":["2015-07-06\\\\n20:30:00"],"summary":["Weekly meeting + Show & Tell (Hangout)"],"description":["Weekly Bullets (20 minutes): "]}' console.log(JSON.parse(json)) snippet.log(JSON.stringify(JSON.parse(json))) 

 <!-- Provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 --> <script src="http://tjcrowder.github.io/simple-snippets-console/snippet.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> 

If the string you are working with is the result of an external call and you can't change the \\n to \\\\n manually, then this can be achieved with a simple replace:

json = json.replace(/\\n/g, "\\\n");

Answer 2

Here you are, a \\n token in your string, let remove it:

 var data = '{"query": "my schedule today","type": "timeline","title": "Today events:","time":["2015-07-06\\n20:30:00"],"summary":["Weekly meeting + Show & Tell (Hangout)"],"description":["Weekly Bullets (20 minutes): "]}'.replace('\\n', ''); var data = JSON.parse(data); alert(data.query); 

Hope this helps.
