Retrieving JSON data using a jQuery AJAX call

I'm struggling with parsing JSON data from a PHP file to jQuery. I've been searching for the right method, but it's been challenging. Any assistance would be greatly appreciated. It must be done within a function.

Currently, I have reached this point:

$.ajax({

    url: "Scripts/Interactions.php",
    type: "POST",
    dataType: "json",
    success: function(data){
        $.each(data, function(i, grab){
        alert(grab.AgentFullName);

        })

    }

})

While this is functional, there is an issue where it displays 'Undefined' before the first row, regardless of the column suggested.

Here is a snippet of my JSON Output data. It mainly consists of random Ipsum Lorem text as I am still early in the development stages. I have validated the data using online JSON format checkers and it has returned as valid.

Thank you in advance for any assistance!

Answer №1

The issue lies in the fact that the first element in your array is a string, not an object. This is why you're receiving undefined when trying to access grab.AgentFullName—the string "results" does not have this property.

To correct this, you can update your array like so:

[
   {
      "InteractionID":"1",
      "AgentFullName":"Peter Germein",
      "InteractTopics":"Behaviour, Attendance, Attitude, Performance, Closing",
      "InteractDiscussion":"Cras at nisl lorem, a lacin...",
      "InteractAction":"Morbi quis nunc in odio eg...",
      "InteractNotes":"Quisque et ante ut nis..."
   },

Alternatively, if you intended to structure your data differently, consider the following format:

{
   "results": [
   {
      "InteractionID":"1",
      "AgentFullName":"Peter Germein",
      "InteractTopics":"Behaviour, Attendance, Attitude, Performance, Closing",
      "InteractDiscussion":"Cras at nisl lorem, a lacin...",
      "InteractAction":"Morbi quis nunc in odio eg...",
      "InteractNotes":"Quisque et ante ut nis..."
   },  
   {
      "InteractionID":"2",
      "AgentFullName":"Peter Germein",
      "InteractTopics":"Behaviour, Attendance, Attitude, Performance, Closing",
      "InteractDiscussion":"....",
      "InteractAction":"Morbi quis nunc in ...",
      "InteractNotes":"Quisque et ante ut nisi ..."
   },

This structure would require parsing data as follows:

$.each(data.results, function(i, grab){
   alert(grab.AgentFullName);
})

Answer №2

[
   "outcomes",
   {
      "ID":"1",
      "RepresentativeName":"Peter Germein",

Noticing the start of your json, it might be better to use "outcomes": rather than "outcomes",
