Howdy,
The requirements for proper JSON syntax are strict, and not the same as
JavaScript Object literals. The names of properties must be quoted with
double quotes, so you might prefer to use single quotes for the outermost
string quoting and double quotes inside. E.g.
var haha =
'{' +
' "cols":[{"id": "task", ...}]' +
'}';
