Hi I get "Uncaught SyntaxError: Unexpected token ILLEGAL" error, when I run this code
str += "{'value': "+ response_imdb[count] +",
'color':#"+ colorValue +",
'label': "+ response_labels[count] +"
}";
Thanks.

1If you copy/pasted that code from somewhere, the problem is likely to be a stray invisible character somewhere in the text. Try typing the text in by hand. edit or the newline; gee I'm blind sometimes :)– PointyCommented Dec 31, 2015 at 20:02

does it say the line and token?– user2486953Commented Dec 31, 2015 at 21:08

This question is similar to: How do I break a string across more than one line of code in JavaScript?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem.– dumbassCommented Jan 16 at 19:45

Here is another easy way.
str += JSON.stringify({
value: response_imdb[count],
color: '#' + colorValue,
label: response_labels[count]
});

It's a nice way to do it, but it doesn't really answer the question. Commented Dec 31, 2015 at 20:05

The answer was already posted by the time I posted the answer. I thought this was a good aside. Commented Dec 31, 2015 at 20:06
In JavaScript you cannot have multi-line strings (unless you add a backslash to the end of each line).
Make them multiple strings and concatenate them using +, like so:
str += "{'value': "+ response_imdb[count] +"," +
"'color':#"+ colorValue +"," +
"'label': "+ response_labels[count] +
"}";

Javascript doesn't allow line breaks in strings. You heave line breaks after ", at the end of each line. You should change it to:
str += "{'value': "+ response_imdb[count] +",\n"+
'color':#"+ colorValue +",\n"+
'label': "+ response_labels[count] +",\n"+
}";
But it's almost always wrong to try to create JSON strings by hand. Use a function for it, like JSON.stringify in Javascript, json_encode in PHP, etc.
There are some other problems there. If the string is going to be parsed as JSON, it the property names need to be in double quotes, not single quotes. And # + colorValue needs to be in quotes to be a string.
