I am trying to parse it like this.

function SortByName(x,y) {        
  return ((x.LastName == y.LastName) ? 
      0 : ((x.LastName > y.LastName) ? 1 : -1 ));    
}   

function RenderPatientSearchData(PatientSearchResponse){
    var PatientSearchData = JSON.parse(PatientSearchResponse);
    var results = PatientSearchData['PatientSearchResult'];
    results.Patient.sort(SortByName);
    for (i = 0, len = results.PatientSearchResult.Patient.length; i < len; i++) {
        // some code here
    }
    //....
}

How can i append key,valu开发者_运维知识库e pair to my JSON. I want to append

Header:'somevalue'

how would i append a Header label to first items of each data. some like which will make me differentiate that these are A Names , these are B Names...

You can see a sample response of the data in this link... something like this

https://github.com/appcelerator/KitchenSink/raw/master/Resources/examples/table_view_headers.js

It's pretty simple if you want to add properties to a Javascript object (as opposed to manipulating a JSON string). Wherever you want to add 'Header': 'somevalue' just do:

PatientSearchData.Header = 'somevalue';
