转义JSON字符串中的双引号

Question

我在这里有一个真正的大脑块，看起来太简单了。如何在单引号的JSON字符串中转义双引号字符串：

var json = '{ "quote": ""Hello World", he said." }';
var obj = JSON.parse(json);

我试过了：

• '{ "quote": "\"Hello World\", he said." }'
• '{ "quote": "\\\"Hello World\\\", he said." }'
• '{ "quote": """Hello World"", he said." }'

每个都会导致各种语法错误。预期产出是：

var obj = {
  "quote": "\"Hello World\", he said."
};

Answer 1

我可能错了......但是因为你希望输出是

"quote": "\"Hello World\", he said."

你应该通过像这样嘲笑它来尝试它：

'{ "quote": "\\"Hello World\\", he said." }'

Answer 2

如果你想要

{ "quote": "\"Hello World\", he said." }

然后注意你只需要转义反斜杠，因为"在单引号中没有特殊含义：

'{ "quote": "\\"Hello World\\", he said." }'

Answer 3

我试过

var json = '{ "quote": "\\"Hello World\\", he said." }';

作品。
