Question

I have a json like

 var jsonObject = {
    "key": [
        {
        "key1": "value1",
        "info": "info"},
    {
        "key2": "value2",
        "info": "info"}
    ]
};​  

I need to retrieve the key and value from this but dynamically, assuming that I don’t know the JSON since it will be generated from the web service..

If you need to process the JSON object in JavaScript, you’ll need a recursive function like this:

function processObject(jsonObject) {
  for (var property in jsonObject) {
    if (jsonObject.hasOwnProperty(property)) {
      console.log(property+'='+jsonObject[property]);
      if (typeof (jsonObject[property]) == 'object') {
        processObject(jsonObject[property]);
      }
    }
  }
}

Replace the console.log with whatever you want to do to the data.
