Question

Here is my JSON which I need to parse:

{"opcode":"groupdetails",
 "status":"success",
 "data":[{"Group ID":5,"Group Name":"data structure","Group Subject":"computer science","Role Type":"Teacher"},{"Group ID":4,"Group Name":"information technology","Group Subject":"computer science","Role Type":"Student"},{"Group ID":6,"Group Name":"data mining","Group Subject":"computer science","Role Type":"Parent"},{"Group ID":7,"Group Name":"dccn","Group Subject":"computer science","Role Type":"Teacher"}]}

I have tried and implemented the solution provided here and this is the implementation of JS that was defined in there solution, which parses only the JSON array

for (var i = 0; i < data.data.length; i++) 
 {
    var object = data.data[i];
     for (property in object) 
     {
        var value = object[property];
        alert(property + "=" + value);
     }
 }

the outer JSON data is returned from server and yes I have tried parsing using the following code and there is no result:

for (var i = 0; i < data.length; i++) 
{
 var object = data[i];
 for (property in object) 
 {
    var value = object[property];
    alert(property + "=" + value);
 }
}

How can I parse the entire JSON using a single method instead of parsing the JSON array separately?

Try this:

for(var key in data) {
    if(typeof data[key] === "object") {
        for(var i = 0; i < data[key].length; i++) {
            for(var property in data[key][i]) {
                 alert(property + " = " + data[key][i][property]);
            }
        }
    } else if(typeof data[key] === "string") {
        alert(key + " = " + data[key]);
    }
}
