Tips on extracting a value from a JSON response

After calling my controller, I receive the JSON result below

{"data":"Monday"}

The data retrieved can be any day of the week (Sunday, Monday, etc...)

If the call is successful, I intend to execute this in the AJAX call

success: function(Response){
        var myresponse = Response.data;
        alert(myresponse);
}

Unexpectedly, I am receiving 'undefined' instead.

Answer №1

If you're confident that the server is sending a JSON response, you have the option to utilize the Ext.JSON class for JSON decoding.

Using the decode() method, you can transform a string into an object, making it simple to retrieve the data.

For instance:

var jsonObject = Ext.JSON.decode(Response.responseText);
var myData = jsonObject.data; 

Answer №2

When loading this particular string with jQuery, the easiest option would be to utilize $.getJSON. This function seamlessly parses the string and delivers the object as the result to the 'success' function.

Answer №3

experiment with utilizing a

console.log(Response);

for the purpose of examining the contents within Response

Answer №4

The system may interpret your input as a string. To handle this, you can use the following approach:

success: function(Result){
        alert(typeof Result);
        var myResult = Result.data;
        alert(myResult);
}

If it indicates that Result is a string, ensure that your framework recognizes that the data received is in JSON format. In jQuery, you can use $.getJSON() function for this purpose.
