JSON解析-名称内的单引号 [英] JSON parse - single quote inside name

问题描述

在Django模板中，我已打印出如下数据:

In Django template I have printed out data like this:

P.place = '{{place.json|safe}}';

然后在JavaScript文件中像这样对它进行解析:

Then in JavaScript file I'm paring it like that:

place = JSON.parse(P.place);

一切都适合这样的数据:

Everything is fine for data like that:

{"category": "Cars", "name": "Z"}

因为字符串看起来像这样:

Because string looks like that:

P.place = '{"category": "Cars", "name": "Z"}'

因此，我可以使用JSON.parse方法witch接受字符串作为输入来解析它.

So, I can parse it using JSON.parse method witch accept strings as input.

问题是当我得到这样的数据时:

Problem is when I get data like that:

{"category": "Cars", "name": "Wojtek's Z"}

因为JSON解析器的输入字符串如下所示:

Because than input string for JSON parser looks like that:

'{"category": "Cars", "name": "Wojtek'

我无法在JSON字符串中转义单引号，因为这样JSON字符串将变为无效.基于相同的原因，我无法用双引号替换周围的引号，并且无法在JSON字符串中转义双引号.

I cannot escape single quote inside JSON string, because then JSON string become invalid. From the same reason I cannot replace surrounding quotes by double and escape double quotes inside JSON string.

我的解决方案如下:

在HTML模板中:

P.place = {{place.json|safe}};

然后用JavaScript

Then in JavaScript

var place = JSON.stringify(P.place);
place = JSON.parse(place);

它可以工作，但不是IMHO的最佳解决方案.

It works, but it is not optimal solution IMHO.

如何用更切肉的方式解决这个问题?

推荐答案

我可以想到两种可能性:

I can think of two possibilities:

创建类型为application/json的脚本元素，将模板数据注入其中，然后读取其数据，例如.

Create a script element of type application/json, inject your template data into it, then read its data, eg.

<script id="place-json" type="application/json">
  {{place.json|safe}}
</script>
<script type="application/javascript">
  P.place = $('#place-json').text();
</script>

或者，在注入字符串之前手动转义单引号，例如.

Or, manually escape the single quotes before injecting the string, eg.

simplejson.dumps(yourdata).replace("'", r"\'")
