Question

function (data) {
    //add values based on activity type
    //data = JSON.parse(data);
    //alert(abc.Phone1);

    alert(data.myName)

    alert(data.toString());
    if (activityType == "Phone") {
    }
    return;

},

As you can see this callback function of $.ajax taking JSON data from controller.

For example:

[{"name":"myName" ,"address": "myAddress" }]

In this case my first alert giving me undefined and second/third alert popup comes up with:

[{"name":"myName" ,"address": "myAddress" }]

How can I access value by name so that my first alert filled out with myName which is value of name?

Answer 1

In stead of parsing JSON you can do like followng:

$.ajax({
  ..
  dataType: 'json' // using json, jquery will make parse for  you
});

To access a property of your JSON do following:

data[0].name;

data[0].address;

---

Why you need data[0] because data is an array, so to its content retrieve you need data[0] (first element), which gives you an object {"name":"myName" ,"address": "myAddress" }.

And to access property of an object rule is:

Object.property

or sometimes

Object["property"] // in some case

So you need

data[0].name and so on to get what you want.

If you not

set dataType: json then you need to parse them using $.parseJSON() and to retrieve data like above.
