Node.js JSON.stringify() causing " in output. Can't parse with Jquery

Question

I am using Node.js (with Express.js) to pass a JSON data object from the server to the client view.

When I render the JSON object directly to the view I get the JSON object shown on the page as expected (this WORKS):

pageprovider.findAllTag( function(error, pages){     res.send(pages); }) 

And my output looks like this (much bigger, many nested obj)

{"green":{"title":"green","pagesContaining": ""}} 

When I try to pass it to my Jade View like this:

pageprovider.findAllTag( function(error, tagsJSONObj){         //res.send(pages);      pageprovider.findAll( function(error, pages){         res.render('search_tags.jade', { locals: {             title: 'Search by Tags',             'pages': pages,             tagsJSON: JSON.stringify(tagsJSONObj) //pass the tags data as a JSON obj             }         });     }) //pageprovider.findAll }) //pageprovider.findAllTag

The problem
When I pass 'tagsJSON' to the view, the output includes the html entities:

var obj = jQuery.parseJSON( "{"name": 'value'}"); 

JQuery throws an error because it doesn't like '"'. How can I get Node to give me the proper quote, or get jQuery to accept this format?

Any thoughts?

Answer 1

It's because when you call

    res.render('search_tags.jade', { locals: {         title: 'Search by Tags',         'pages': pages,         tagsJSON: JSON.stringify(tagsJSONObj) //pass the tags data as a JSON obj         }     }); 

search_tags.jade is meant to output HTML, so it encodes your quotes. You should use a renderer that doesn't HTML escape, or at least change your view so that your params aren't HTML encoded

If you don't want something in the output escaped, use !{tagsJSON} within the view. However, when outputting JSON, there's no need for a view. you can just take your object, call JSON.stringify. I don't use JADE so I'm not sure if there is a way to create view that can just call JSON.stringify(), but that's what I've done in JSP, velocity, ASP, PHP and Code Igniter (not using JSON.stringify, instead it uses a JSON tool for the given language)

in ejs, its <%- tagsJSON %>

          ^ <---- Note the "-"
