Question

I am currently practicing using Javascript/Dojo. However, I have an error that I am unable to solve:

Uncaught SyntaxError: Unexpected token o

I have made a quick snippet of my problem:

var data = {
    "list": {
        "1": {
            "Relevance": "Low",
            "id": 1,
            "Name": "Inorganic"
        },
        "2": {
            "Relevance": "Low",
            "id": 2,
            "Name": "Mobile"
        }
    }
}

var jsonData = JSON.parse(data);
alert(jsonData.list[1].Name);

It specifically targets the line with:

var jsonData = JSON.parse(data);

I would like to know why this is an error & how I would solve it.

Answer 1

You’re trying to parse a JavaScript object. JSON.parse is for parsing a JSON string representing a JavaScript-like object.

Just skip the parsing altogether:

alert(data.list[1].Name);
