Following is my controller which returns String

@RequestMapping("/hello1")  
    public @ResponseBody  
        String hello1() {  
           String jsonString = "[{\"deviceId\": \"  e71b0be12218393e121cb728595af68995889fb9\",\"deviceName\": \"  Xcaliber?s iPad3\",\"serialNumber\": \"  DMPH9E74DJ8R\",\"modelNumber\": \"  MC706\",\"productType\":\"  iPad3,1\",\"deviceClass\": \"  iPad\"},{\"deviceId\": \"\", \"deviceName\": \"\",\"serialNumber\": \"\",\"modelNumber\": \"\",\"productType\": \"\",\"deviceClass\": \"\"}]";
return jsonString;
} 

I am getting this string as response in javascript. and I am trying follwing code in javascript

var deviceJsonDetails = $.parseJSON(response);
         for(var count = 0;count < response.length; count++){
                             var id = count+1;
                             alert(deviceJsonDetails[count].deviceId);
                             $("#deviceId"+id).html(deviceJsonDetails[count].deviceId);
                             $("#deviceName"+id).html(deviceJsonDetails[count].deviceName);
                             $("#serialNumber"+id).html(deviceJsonDetails[count].serialNumber);
                             $("#modelNumber"+id).html(deviceJsonDetails[count].modelNumber);
    }

But it is giving error on var deviceJsonDetails = $.parseJSON(response); Error: SyntaxError: JSON.parse: expected property name or '}'

Can you please tell me where is the fault or any alternate solution to parse same string in js?

• Check what server returning in HTTP response (Developer Tools in Chrome, Firebug Plugin in Firefox for example) and check if syntax is corrct by using JSONLint web site validator for example. – Serhiy Commented Nov 11, 2013 at 13:10

Check your JSON string in http://jsonlint./

The correct string that you need to parse should be: Remove the "\"

[
    {
        "deviceId": "e71b0be12218393e121cb728595af68995889fb9",
        "deviceName": "Xcaliber?siPad3",
        "serialNumber": "DMPH9E74DJ8R",
        "modelNumber": "MC706",
        "productType": "iPad3,1",
        "deviceClass": "iPad"
    },
    {
        "deviceId": "",
        "deviceName": "",
        "serialNumber": "",
        "modelNumber": "",
        "productType": "",
        "deviceClass": ""
    }
]
