Unraveling complex JSON structures with JavaScript - identifying troublesome characters

Currently, I am utilizing JSON in my JavaScript code. The JavaScript component receives the subsequent JSON message:

{"param1":1, "param2":{"aaa":1,"bbb":2,"ccc":3}, "param3":true}

Within my JavaScript implementation, I have formulated this script:

parsedArgs = JSON.parse(args);
alert(parsedArgs.param2);
parsedArgs.param2= JSON.parse(parsedArgs.param2);

Upon triggering the alert, I observe [Object object], however, attempting to use JSON.parse(parsedArgs.param2) results in a SyntaxError: invalid character.

I aspire to access the internal parameters of param2, yet the JSON parser is encountering issues. Could you kindly assist me? What could be causing this problem?

Regards,

javascriptjson

Answer №1

The issue lies in excessive parsing of your JSON string. The JSON.parse function is recursive, converting a string into a valid JavaScript object following the JSON format. Once you have parsed it with the initial JSON.parse, there is no need to parse the object's properties again as they are already parsed. You can directly access them using parsedArgs.param2.aaa, for instance.

Answer №2

quotation marks are absent from param2

{
    "param1": 1,
    "param2": {
        "aaa": 1,
        "bbb": 2,
        "ccc": 3
    },
    "param3": true
}
