在Ajax中获取json数组

Question

I'm trying to display some data from the ajax response as below.

$.post(
            '/tests/elementary/'+($(this).attr('data-test-id'))+'/get-details', // location of your php script
            {
            }, // any data you want to send to the script
            function( data ) {  // a function to deal with the returned information
                if(data.taken =='false'){
                    alert('ok')
                }
                else {

                    $('#test_name').empty().append(data.information);
                    $('#test_point').empty().append(data.details['score']);
                    $('#test_date').empty().append(data.updated_at);


                    for(var i=0;i<data.testlog.length;i++) {
                        var temp = data.testlog[i];
                        $("#test_details_body").append("<tr> <td>"+ (i+1) +"</td> <td>"+temp['operand1']+' '+temp['operator']+' '+temp['operand2']+"</td><td>"+temp['user_answer']+"<td>"+temp['correct'] +"</td><tr>")
                    }



                }
            });
        });

But I'm getting Uncaught SyntaxError: Unexpected token o error.

response:

{
    "success":"true",
    "taken":"true",
    "details":"{\"id\":2,\"user_id\":1,\"test_id\":9,\"token\":\"682c5de08481081b940364416cdce99d\",\"score\":80,\"attempts\":2,\"created_at\":\"2015-02-16 02:09:12\",\"updated_at\":\"2015-02-16 02:09:12\",\"course_id\":7}",

    ]
}

php script for fetching data

public function getTestDetails($id){

        $exists = Testresult::where('user_id', Auth::id())->where('test_id', $id)->first();

        if($exists==null){
            return Response::json(["success"=>"true", "taken"=>"false"]);
        }
        else{

            $updated_at = date("d-M-Y H:m:s", strtotime($exists->updated_at));
            $testLog = Testlog::where('token', $exists->token)->get();

            $info = Test::where('id', $id)->pluck('name');
            return Response::json(["success"=>"true", "taken"=>"true",
                                    "details"=>"$exists",
                                    "information"=>$info,
                                    "updated_at"=>$updated_at,
                                    "testlog"=>$testLog]);
        }


    }

Am I doing it right?

Answer 1

It doesn't look like data.testlog needs to be parsed you could do this

var testlog = data.testlog
for(var i = 0; i < testlog.length; i++){
    var temp = testlog[i]
    $('#test_details_body').append('<tr><td>' + (i+1) + '</td><td>' + temp.operand1 + ' ' + temp.operator + ' ' + temp.operand2 + '</td><td>' + temp.user_answer + '<td>' + temp.correct + '</td><tr>')
}

Also I changed a couple things in your code (spacing, using single rather than double quotes, and using dot notation for call values from an object.)
