我在JSON parse函数中使用转义引号时，遇到了一个常见的问题。如果存在转义引号，在本例中为“test”，则会导致以下错误
'SyntaxError: JSON Parse error: Unterminated string'.
var information = JSON.parse('[{"-1":"24","0":"","1":"","2":"","3":"0.0000","4":"","5":"0.00","6":"0.00","7":"1.00","8":"0","9":"false","10":"false","11":[""],"12":"","13":"","14":"test\""}]');
JSON Lint验证该JSON为有效的。

你需要像这样"test\\""多加一个转义符号
var information = JSON.parse('[{"-1":"24","0":"","1":"","2":"","3":"0.0000","4":"","5":"0.00","6":"0.00","7":"1.00","8":"0","9":"false","10":"false","11":[""],"12":"","13":"","14":"test\\""}]');
document.body.innerHTML = '<pre>' + JSON.stringify(information, null, 4) + '</pre>';第一个反斜杠转义javascript字符串文字中的第二个反斜杠。第二个反斜杠转义JSON字符串文字中的引号。
所以它被解析了两次，需要转义两次。
因此，即使它是有效的JSON，您也需要一个javascript字符串文本的转义符，来转义JSON中使用的转义符。
