The elements within the array have not been defined

Why is the results array showing as undefined?

I am having trouble displaying the objects inside the results array. I have attempted to do so with console.log(data.results[0].bodyColor) but encountered an error. When I try accessing (data.results), it returns undefined. Even trying (data.results[0]) triggers an error message. It's perplexing why the array appears as undefined when I can clearly see it in my console. How can I print out the value of AirBagLocFront from this array?

Answer №1

There seems to be a minor error in your code. The correct term is Results, not results. Additionally, the variable Results is an array that contains a single object. To navigate through this data structure efficiently, you can utilize a for...in loop. Below is a functional code snippet:

$.ajax({
  url: "https://vpic.nhtsa.dot.gov/api/vehicles/DecodeVINValuesBatch/",
  type: "POST",
  cache: true,
  data: {
    format: "json",
    data: "WBAPK5C52AA599960;"
  },
  dataType: "json",
  success: function(data) {
    var result = data.Results[0];
    for (var property in result) {
      if (result.hasOwnProperty(property)) {
        console.log(property + ' - ' + (result[property] ? result[property] : 'N/A'));
      }
    }
  }
});
