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

express, jquery, json, node.js, pug

Solution

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)

Problem

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?
