JSON from EJS to JSON object in JS

Question

I am using EJS with Node.JS, and am passing a JSON object into it, but need to have access to it as a usable object in the page. I am getting the unexpected token o error from this:

var initData=JSON.parse(<%-JSON.stringify(list)%>);

I cant figure out whats wrong here.

This is what it looks like in the file when rendered:

var initData=JSON.parse([{"title":"South Hills Health System - University Health Center","adr":"200 Lothrop St,15213","coords":"40.441875,-79.960813","images":[],"tags":[],"_id":"51c0e9798384f40000000017"},{"title":"Bombay Food Market","adr":"4605 Centre Avenue, Pittsburgh, PA 15213, USA","coords":null,"images":[],"tags":["indian","groceries","ethnic","store"],"_id":"51c0519e02b7cbec73000002"}]);

try this:

var initData = JSON.parse('<%-JSON.stringify(list)%>');

OR:

var initData = <%-JSON.stringify(list)%>;

first one worked perfectly! could you explain why the single quotes makes it work though?

@GeorgeL JSON.parse takes STRING as parameter and look at your output, you are passing array in JSON.parse. single quotes does this: JSON.parse('[{ "title": "..." }]') instead of this: JSON.parse([{ "title": "..." }])

why is initData an object instead of a string? we stringified it

@OMGPOP I wonder the same and I guess it's related to the <%- operator somehow. <%= would fail I think.

Be careful, this method does not work for arbitrary objects. For example, regexes end up as empty objects. { a: /bcd/ } will output { a: {} }. This is because regexes have serialization issues - stackoverflow.com/questions/12075927/serialization-of-regexp. I don't know if other types have this problem.
