Question

I’ve generated some JSON and I’m trying to pull it into an object in JavaScript. I keep getting errors. Here’s what I have:

var data = '{'count' : 1, 'stack' : 'sometext\n\n'}'; var dataObj = eval('('+data+')'); 

This gives me an error:

unterminated string literal 

With JSON.parse(data), I see similar error messages: ‘Unexpected token ↵‘ in Chrome, and ‘unterminated string literal‘ in Firefox and IE.

When I take out the \n after sometext the error goes away in both cases. I can’t seem to figure out why the \n makes eval and JSON.parse fail.

This is what you want:

var data = '{"count" : 1, "stack" : "sometext\\n\\n"}'; 

You need to escape the \ in your string (turning it into a double-\), otherwise it will become a newline in the JSON source, not the JSON data.
