Question

I have this example where I am trying to access json value, but it does not even produces any alert. What is the problem?

My JSON

{
 "response": [
{
  "id": "0",
  "elementName": "osname",
  "isEqual": true,
  "isPrasentinXml1": true,
  "isPrasentinXml2": true,
  "attribute": [
    {
      "name": "osname",
      "firstValue": "Linux\u000a",
      "secondValue": "SunOs\u000a"
    }
  ]
},
{
  "id": "1",
  "elementName": "hostname",
  "isEqual": false,
  "isPrasentinXml1": true,
  "isPrasentinXml2": true,
  "attribute": [
    {
      "name": "hostname",
      "firstValue": "estilo\u000a",
      "secondValue": "buckeye.informatica.com\u000a"
    }
  ]
}
]
}

I want to fetch Linux\u000a and SunOs\u000a, so i wrote

alert(compareData.response[0].attribute[0].firstValue+", "+compareData.response[0].attribute[0].secondValue);

Note: compareData Is where my data is in actual code

Your error was that you have quotes around your JSON and it was treated as a string. Also you forgot to replace compareData variable name with jsonobj in the second alert. Try the fiddle below, it seems it is what you want.

EDIT:

If your JSON is really represented by the string take a look at Michael Sagalovich solution.
