JSON.stringify doesn't escape?

问题

I'm using `JSON.stringify? to stringify an object, but the quotes are not escaped? Am I misunderstanding that it's suppose to escape the quotes?

This is outputted into the template without any of the quotes being escaped:

{"console":{"free":false}}

回答1:

The quotes around property names are not supposed to be escaped, only quotes inside strings. Your JSON is fine :)

回答2:

It doesn't escape characters, no, there's encodeURIComponent for that, and you can use them together, as in encodeURIComponent(JSON.stringify(obj))

回答3:

stringify the object twice does the trick

console.log(JSON.stringify(JSON.stringify({"console":{"free":false}})));
// "{\"console\":{\"free\":false}}"

回答4:

Without the offending code to inspect, I'm wondering if something else is happening. As a test...

<div id="test"/>

var ex = {'test':'This is "text".'};

$('#test').text(JSON.stringify(ex));

Outputs: {"test":"This is \"text\"."} (< Note the escaped double quotes)
