Invoke the REST API by utilizing Ajax through invoking a function

Question

Invoke the REST API by utilizing Ajax through invoking a function

I have a task that involves calling a REST API and getting the response. Currently, I am able to achieve this by directly making the AJAX call, which works perfectly fine. However, I now need to refactor this process into a function where I can pass two parameters that will be used in the URL. The goal is to return the response from this function so that it can be utilized in other classes.

function fetchData(param1, param2) {
  $.ajax({
    url: "BaseURL" + param1 + "/" + param2
  }).then(function(data) {
    if (data.test == null)
      self.prop1(data.test);
    if (data.test2 !== null)
      self.prop2(data.test2);
    if (data.test3 !== null)
      self.prop3(data.test3)
  });
}

Can you please provide any suggestions on how to approach this? Let me know if you require any additional information from my end.

It is recommended to construct the URL outside of the function for better organization:

// Declare the URL components
var BaseURL = 'www.baseurl.com';
var param1 = '<param1>';
var param2 = '<param2>';
var URL = `${BaseURL}${param1}/${param2}`

// Function to handle AJAX POST request
function AJAXPost(RequestType, formData, URL){
    $.ajax({
      url: URL,
      type: RequestType,
      data: formData
      // Test for success or error
    })
}

A convenient way to fetch data is by defining a function that takes parameters and a callback for handling the retrieved information

function fetchData(param1, param2, callback) {
  $.ajax({
    url: "BaseURL"+param1+"/" + param2
  }).then(function(data) {
    callback(data);
  });
}

Alternatively, you can use async/await for asynchronous operations

const fetchDataAsync = async (param1, param2) => {
  try {
    let data = await $.ajax({url: `BaseURL${param1}/${param2}`});
    return data;
  } catch(e) {
    console.error(e);
  }
}
