如何解析JSON对象中的JSON字符串

[英]How to parse JSON string within a JSON object

There is a JSON string in a JSON object JSON对象中有一个JSON字符串

{
 "abc": "{\n  \"_count\": 10,\n  \"_start\": 0,\n  \"_total\": 60\n }",
"success": true
}

I want to get the the the value of abc as JSON object in javascript. 我想在javascript中将abc的值作为JSON对象获取。

You would use something like this: 您将使用以下内容:

var obj = JSON.parse(JSON.parse(the_string).abc);

NOTE: Your JSON is invalid. 注意:您的JSON无效。 Please correct it. 请更正。 It should be somewhat like the below: 它应该类似于以下内容:

{
 "abc": "{\n  \"_count\": 10,\n  \"_start\": 0,\n  \"_total\": 60\n}",
"success": true
}

If your object is in a variable called obj then obj.abc will return the string value. 如果您的对象位于名为obj的变量中,则obj.abc将返回字符串值。 As this is a JSON string encoding a JavaScript object you need to use JSON.parse to convert it : var abc = JSON.parse (obj.abc); 由于这是一个编码JavaScript对象的JSON字符串,因此您需要使用JSON.parse进行转换: var abc = JSON.parse (obj.abc); . You now have access to the field vaues abc._count , abc._start and abc._total . 现在,您可以访问字段vaues abc._countabc._startabc._total

You can do something like this 你可以做这样的事情

var json = '{"abc": {"_count": 10,"_start": 0, "_total": 60 },"success": true}';
var obj = JSON.parse(json);
console.log(obj.success);
console.log(obj.abc['_count']);
