JSON Javascript逃脱

问题描述

所以我下面有一些我的动态JSON示例，我正在做的就是正确地转义所有内容，以便JSON.parse或Jquery.parseJSON正确处理它，由于某种原因它当前不是。我已经尝试更换所有引号，但它没有解决任何问题...

So i have some of my example dynamic JSON below, what i'm having trouble doing is escaping everything properly so that it is properly processed by JSON.parse or Jquery.parseJSON, which for some reason it currently isnt. I've tried replacing all quotes but it doesn't solve anything...

推荐答案

在JSON内部，字符串中的引号需要使用反斜杠进行转义： {key：prop with \quote} 。

Inside JSON, quotes within strings need to be escaped with a backslash: {"key": "prop with \" quote"}.

在JavaScript中，字符串文字中的引号和反斜杠需要使用反斜杠进行转义：string with \\ \\\backslash和\quote。

Inside JavaScript, quotes and backslashes within string literals need to be escaped with a backslash: "string with \\backslash and \" quote".

如果你真的需要在JS字符串文字中使用JSON（没有理由要做到这一点），你需要双重逃避它们： json ={\key：\prop with \\\quote and \\\\
linebreak \ }。对于Windows Phone周围的报价，你还没有这样做。

If you really would need to use JSON in JS string literals (there is no reason to do that), you would need to double-escape them: json = "{\"key":\"prop with \\\" quote and \\n linebreak\"}". You haven't done so for the quotes around "Windows Phone".

但是，在处理这些问题时你一定做错了。通常你从ajax调用中获取JSON字符串等，你可以将它们作为字符串值获取。如果你想将一些服务器创建的JSON直接回显到js脚本中，你不需要将它包装在一个字符串文字中 - 它已经是有效的Object Literal语法。

However, you must've done something wrong when dealing with such problems. Usually you get JSON strings from ajax calls and such, where you get them already as a string value. If you want to echo some sever-created JSON directly into a js script, you don't need to wrap it in a string literal - it is already [nearly] valid Object Literal syntax.
