json convert javascript array

Question

I have json message in this format

{"id":21,"image":"binary64image","pdate":"2014-01-27"},
{"id":22,"image":"binary64image","pdate":"2014-01-27"},
{"id":21,"image":"binary64image","pdate":"2014-01-27"}

and I want to convert this into javascript array, I have tried

        var txt = '{ "potholes" : [' + data + ']}';
        var jsonObj = eval("(" + txt + ")");            
        alert(jsonObj.potholes[1].id);

and

        var potholes = JSON.parse(data);
        alert(potholes[1].id);

neither worked. The data is there as it is in a success to an ajax call which returns json object.

You can convert your JSON response in JavaScript array like below :

var data = '{"id":21,"image":"binary64image","pdate":"2014-01-27"},{"id":22,"image":"binary64image","pdate":"2014-01-27"},{"id":21,"image":"binary64image","pdate":"2014-01-27"}';
var result = eval("["+data+"]");  //convert your response into JavaScript array

for(var i in result) // read your array value
    alert("id : "+result[i].id+" --> image : "+result[i].image+" --> pdate : "+result[i].pdate);

You should convert your input data to an array ( fiddle ):

var input = '{"id":21,"image":"binary64image","pdate":"2014-01-27"},{"id":22,"image":"binary64image","pdate":"2014-01-27"},{"id":21,"image":"binary64image","pdate":"2014-01-27"}',
    inputArr = '[' + input + ']',
    arr = JSON.parse(inputArr);
for (var i in arr)
    console.log(arr[i].id);
