JSON Stringify Ouput to Multiple Lines
提问by Joey N
I'm writing a simple JS app that takes in a JSON file, displays the information to the user and allows them to modify it, and then allows them to re-export the JSON. However, the JSON that is being brought in is multi-line; each key/value is on its own line. When I use .stringifyto output the JSON, it all appears on one line. Is there any way for the stringify method to separate the lines?

],
"lvl2":[

]}
}
But when I output, it all shows:

You can use the spaceparameter of the stringify method. From the official page, here is the relevant excerpt:
您可以使用stringify 方法的space参数。从官方页面，这里是相关的摘录：
JSON.stringify({ a: 2 }, null, " "); // '{\n "a": 2\n}'

you can also use.
你也可以使用。
var json = JSON.stringify({ uno: 1, dos : {"s":"dd","t":"tt"} }, null, '\t');
console.log(json);

没关系
JSON.stringify(JSON variable, null, "\t");
