Javascript 无法解析 JSON 字符串

Question

我试图解析这个 JSON 字符串:

{"query": "my schedule today","type": "timeline","title": "Today events:","time":["2015-07-06\n20:30:00"],"summary":["Weekly meeting + Show & Tell (Hangout)"],"description":["Weekly Bullets (20 minutes): "]}

这是一个有效的 JSON(在 jsonformatter.curiousconcept.com 上检查过)。但是，我收到错误:

SyntaxError: Unexpected token

在(文件 angular.js)中:

function fromJson(json) {
    return isString(json)
        ? JSON.parse(json)
        : json;
}

有人有想法吗？

Answer 1

问题出在文本中的\n，需要转义为\\n

var json = '{"query": "my schedule today","type": "timeline","title": "Today events:","time":["2015-07-06\\n20:30:00"],"summary":["Weekly meeting + Show & Tell (Hangout)"],"description":["Weekly Bullets (20 minutes): "]}'

console.log(JSON.parse(json))
snippet.log(JSON.stringify(JSON.parse(json)))

<!-- Provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->

如果您正在使用的字符串是外部调用的结果，并且您无法手动将 \n 更改为 \\n，那么这可以是通过简单的替换实现:

json = json.replace(/\\n/g, "\\\n");
