JSON Parse不工作，解析二维数组

Question

I am trying to parse this LOCAL XMLhttprequest, I am getting back the right response text and displaying it in safari. When I make an object to JSON.parse() the responsetext,I am getting errors like "unidentified token '"' " or "expected '}' " no matter how I change the .txt file, it will not parse into an object for me

I have tried to change the .txt to the right JSON format with no luck

{playerGrid: [["3","2","2","2","2","2","2","3","3","3"], ["3","2","2","2","2","2","2","2","2","2"], ["3","2","2","2","2","2","2","2","2","3"],["3","2","2","2","2","2","2","2","2","3"], ["4","2","2","2","2","3","2","2","2","3"], ["2","2","2","2","7","3","2","2","2","3"], ["2","2","2","2","7","2","2","2","2","2"], ["2","2","2","3","3","3","2","2","2","2"], ["2","2","2,"2","2","2","2","2","2","2"], ["2","2","2","2","2","2","2","2","2","2"]],
computerGrid: [["2","2","2","7","4","9","9","2","2","2"], ["2","9","2","2","2","2","2","2","2","2"], ["2","9","2","2","2","2","2","2","2","2"], ["2","9","2","2","9","9","2","2,"2","2"], ["2","2","2","2","2","2","2","2","2","2"], ["9","9","9","9","9","2","2","2","2","2"], ["2","2","2","2","7","2","2","2","9","2"], ["2","2","2","2","2","2","2","2","9","2"], ["2","2","2","2","2","2","2","2","9","2"], ["2","2","2","2","2","2","2","2","9","2"]]};

here is my JOSN .txt

function fileRequest()
{

  var localRequest = new XMLHttpRequest();

  localRequest.open("GET", "sampleJSON.txt", false);

  localRequest.send(null);

  document.getElementById("jsonDiv").innerHTML = localRequest.responseText;

  var jsonObject = JSON.parse(localRequest.response);

  document.getElementById("jsonParsed").innerHTML = jsonObject.computerGrid;

}

here is my simple function, I first display the response, and then it errors when I am trying to parse the data. Thanks

I expect an object that I can .computerGrid or .playerGrid.

Answer 1

You have some errors in your json, just search by "2, , there are 2 occurences, it should be "2", .
You are missing a closing " .

Also, in order to the JSON to be valid, it should look like this:

{"playerGrid":[["3","2","2","2","2","2","2","3","3","3"],["3","2","2","2","2","2","2","2","2","2"],["3","2","2","2","2","2","2","2","2","3"],["3","2","2","2","2","2","2","2","2","3"],["4","2","2","2","2","3","2","2","2","3"],["2","2","2","2","7","3","2","2","2","3"],["2","2","2","2","7","2","2","2","2","2"],["2","2","2","3","3","3","2","2","2","2"],["2","2","2","2","2","2","2","2","2","2"],["2","2","2","2","2","2","2","2","2","2"]],"computerGrid":[["2","2","2","7","4","9","9","2","2","2"],["2","9","2","2","2","2","2","2","2","2"],["2","9","2","2","2","2","2","2","2","2"],["2","9","2","2","9","9","2","2","2","2"],["2","2","2","2","2","2","2","2","2","2"],["9","9","9","9","9","2","2","2","2","2"],["2","2","2","2","7","2","2","2","9","2"],["2","2","2","2","2","2","2","2","9","2"],["2","2","2","2","2","2","2","2","9","2"],["2","2","2","2","2","2","2","2","9","2"]]}

Keys, playerGrid and computerGrid must be between " .

Answer 2

1. Use JSON.parse(localRequest.responseText)

2. Your JSON is incorrect, you are missing quotes around some numbers like "2,

3. Object Keys "playerGrid" and "computerGrid" must be quoted too

 let d = `{ "playerGrid": [ ["3","2","2","2","2","2","2","3","3","3"], ["3","2","2","2","2","2","2","2","2","2"], ["3","2","2","2","2","2","2","2","2","3"], ["3","2","2","2","2","2","2","2","2","3"], ["4","2","2","2","2","3","2","2","2","3"], ["2","2","2","2","7","3","2","2","2","3"], ["2","2","2","2","7","2","2","2","2","2"], ["2","2","2","3","3","3","2","2","2","2"], ["2","2","2","2","2","2","2","2","2","2"], ["2","2","2","2","2","2","2","2","2","2"]], "computerGrid": [ ["2","2","2","7","4","9","9","2","2","2"], ["2","9","2","2","2","2","2","2","2","2"], ["2","9","2","2","2","2","2","2","2","2"], ["2","9","2","2","9","9","2","2","2","2"], ["2","2","2","2","2","2","2","2","2","2"], ["9","9","9","9","9","2","2","2","2","2"], ["2","2","2","2","7","2","2","2","9","2"], ["2","2","2","2","2","2","2","2","9","2"], ["2","2","2","2","2","2","2","2","9","2"], ["2","2","2","2","2","2","2","2","9","2"]] }`; console.log(JSON.parse(d)) 

PS: you can always validate your json with codebeautify.org/jsonvalidator
