For IEworks fine, in Chromeappears "Syntax error: unexpected number"and in Firefoxthe message is "SyntaxError: JSON.parse: expected ',' or '}' after property value in object"
对于IE工作正常，在Chrome 中出现"Syntax error: unexpected number"，在Firefox中消息是"SyntaxError: JSON.parse: expected ',' or '}' after property value in object"
In various online JSON parsers and validators the format of the response seems to be OK, but in firefox and chrome not works.
在各种在线 JSON 解析器和验证器中，响应的格式似乎没问题，但在 Firefox 和 chrome 中不起作用。
Any idea why this happens?
知道为什么会这样吗？

A number can't start with a not significative 0.
数字不能以不具有意义的 开头0。
This is invalid : "ti": 0000011410
这是无效的： "ti": 0000011410
From JSON.org:
来自JSON.org：
You should fix it at the source but if you can't, assuming your JSON is always similar to this one(no numbers in strings), then you might probably fix it with a regex :
你应该在源头修复它，但如果你不能，假设你的 JSON 总是类似于这个（字符串中没有数字），那么你可能会用正则表达式修复它：
var obj = JSON.parse(str.replace(/ 0+(?![\. }])/g, ' '));
You can't even here use the evil evalbecause "0000011410"would be parsed as a octal :
你甚至不能在这里使用 evileval因为"0000011410"会被解析为八进制：
console.log(eval('({"ti": 0000011410})'));
outputs
产出
{ti: 4872}
This probably explains why it was considered safer to forbid numbers starting with non significative 0in JSON.
这可能解释了为什么0在 JSON 中禁止以非意义开头的数字被认为更安全。

remove 0 in front of the number in the json
去掉json中数字前面的0
