You can start by simplifying this down to where the problem occurs, in bc_list...
您可以首先将其简化为问题发生的位置，在bc_list...
JSON.parse('{"bc_list": ["", "{\"257\":\"14\"}]"]}')
The issue is that your backslashes are being considered for the outer quotes on JSON.parse()instead of the inner data. You must escape the backslashes as well.
问题是您的反斜杠正在考虑用于外部引号JSON.parse()而不是内部数据。您还必须避开反斜杠。
JSON.parse('{"bc_list": ["", "{\"257\":\"14\"}]"]}')
Your whole line fixed becomes:
您的整行固定变为：
JSON.parse('{"start_date_time": ["2012-12-05 04:45:42.135000", "None"], "terminal_no": ["T1081", "None"], "master_doc_no": ["100008", "100008"], "notes": ["", ""], "doc_no": ["1000018", "1000019"], "location_code": ["1005", "1005"], "end_date_time": ["2012-12-05 05:27:04.529000", "None"], "doc_status": ["CC Ended", "Draft"], "bc_list": ["[{\"465\":\"85\"},{\"306\":\"6\"},{\"306\":\"47\"},{\"306\":\"366\"},{\"306\":\"634\"}]", "[{\"257\":\"14\"}]"]}')
Don't use JSON data within strings within JSON data. It's a mess.
不要在 JSON 数据的字符串中使用 JSON 数据。一团糟。

This normally means your you are missing an operator, or have an illegal operator, in a calculation.
这通常意味着您在计算中缺少运算符或使用非法运算符。
For example:
例如：
var a = 1000 * 1000; // correct
var b = 1000 1000; // incorrect
var c = 1234; // correct
var d = 1,234; // incorrect
vars b and d will result in:
vars b 和 d 将导致：
Uncaught SyntaxError: Unexpected number
