Node.js JSON.stringify()导致& quot;在输出。不能用Jquery解析 [英] Node.js JSON.stringify() causing " in output. Can't parse with Jquery
问题描述
我使用Node.js(使用Express.js)将JSON数据对象从服务器传递到客户端视图。
I am using Node.js (with Express.js) to pass a JSON data object from the server to the client view.
当我呈现JSON对象直接到视图,我按预期得到页面上显示的JSON对象(这个WORKS):
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);
})
我的输出看起来像这样(更大,很多嵌套obj)
And my output looks like this (much bigger, many nested obj)
{"green":{"title":"green","pagesContaining": ""}}
当我尝试传递给我的玉视图像这样:
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
问题
当我将'tagsJSON'传递给视图时,输出包括html实体:
The problem
When I pass 'tagsJSON' to the view, the output includes the html entities:
var obj = jQuery.parseJSON( "{"name": 'value'}");
JQuery抛出错误,因为它不喜欢。如何让Node给我正确的引用,或者让jQuery接受这种格式?
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?
任何想法?
推荐答案
这是因为当你调用
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
旨在输出HTML ,所以它编码您的报价。您应该使用不会HTML转义的渲染器,或至少更改您的视图,以使您的参数不是HTML编码。
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
如果您不想要输出转义,在视图中使用!{tagsJSON}
。但是,当输出JSON时,不需要查看。你可以拿你的对象,调用 JSON.stringify
。我不使用JADE,所以我不知道是否有办法创建可以调用 JSON.stringify()
的视图,但这就是我所做的在JSP,速度,ASP,PHP和代码Igniter(不使用 JSON.stringify
,而是使用给定语言的JSON工具)
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)
