Retrieve values from a JSON

I want to extract the tenantId value from the below given json

{
  "ClientAccounts":{
   "@tenantId":"entpriseDemo",
   "clientAccount":[
    {
     "guid":"447a0bac-51e0-4f5f-b504-97dca5825530",
     "totalValueFormatted":"$1,100,000"
    }
   ]
  }
}

This is my javascript function for calling an ajax request and the success function code

$.ajax({
      url: "$clientAccountsURL",
      cache: false,
      dataType: "json", // set to json or xml
      success: function(data){

        alert(data.ClientAccounts.tenantId);


    } 
});

When I'm alerting the value of tenantId in the success function it's returning me undefined value though i checked on the firebug its available in the json array.

Is there any another way to retrieve the value of tenantId.

You can use either object notation or and associative array notation:

In your case, use associative array notation:

alert(data.ClientAccounts["@tenantId"]);

Since the property name contains an @ you will have to access the property using the associative array syntax.

data.ClientAccounts["@tenantId"];

You should be able to access it by using it like an associative array:

data.ClientAccounts['@tenantId']

Use the square brackets notation

data.ClientAccounts['@tenantId']

From this mdn article:

An object property name can be any valid JavaScript string, or anything that can be converted to a string, including the empty string. However, any property name that is not a valid JavaScript identifier (for example, a property name that has a space or a hyphen, or that starts with a number) can only be accessed using the square bracket notation.
