Question

I got a JSON file with value’s that got a whitespace in them. like so:

"Project 3":6

I If try to do something in D3.js with the data like so

var meanProject3 = d3.mean(data, function(d) {return d.project 3 });
console.log(meanProject3);

i got the following error:

Uncaught SyntaxError: Unexpected token } 

If i try it with nodes that don’t have whitespace it works fine.
I can’t edit the json file. Is there any other way to make this work?

Answer 1

You can’t use dot notation when the property name has special characters such as white space. Try:

return d['Project 3']

Note that property names are case-sensitive.
