json error JSON.parse: unexpected end of data error

Question

The following string is returned as response from a web request:

[[1367366400000,6435.00],[1370044800000,349004.49],[1372636800000,1178831.00], [1375315200000,2906943.00],[1377993600000,3571615.00],[1380585600000,3852076.00], [1383264000000,3656850.00],[1385856000000,306884.00]]

now when I try to

var data = $.parseJSON(data);

It is giving me an error:

JSON.parse: unexpected end of data error

I also tried:

var data = $.parseJSON(JSON.stringify(data));

It does not give any error, but it also does not convert the text to JSON object.

The given response from your web request already evaluates as valid javascript. You could pass it to a variable directly, but you need to evaluate it. var data=eval('[[13...'); — SQRCAT

because the response is not JSON at all, it's a simple array and use eval() to parse it in a new variable.

var myVar=null;
eval('myVar=' + response );
if(myVar)
    console.log(myVar);

I don't know who downvoted this and why - it is generally valid. Using eval() may not be considered good practice but its still a valid choice?

I don'r care of downvote, yes ! you could check for count of [ and compare theme to count of ] if if first character is: ([) and last character is: (]) and every brace has a match one for closing brace, that's a good choice
