Can you please let me know if it's possible to store an ajax function/call for future reuse?

While developing a web app using JavaScript and PHP, I've noticed that I keep rewriting the same ajax calls repeatedly. Is there a way to create a reusable function or variable for these calls, with or without parameters?

I'm fairly new to JavaScript, so please bear with me as I am still learning.

Instead of coding like this:

  $("body").on("click", ".all-forms-link", function() {
         $.ajax({ 
            url: "forms.php", 
            type: "post", 
            data: {formsPage: 1}, 
            success: function(data) {
                     stage.html(data)
             }

          }); 
     }); 
     //similar code repeated multiple times

We can approach it in a more organized manner, like shown below:

      function loadForms() {
            $.ajax({ 
            url: "forms.php", 
            type: "post", 
            data: {formsPage: 1}, 
            success: function(data) {
                     stage.html(data)
                                     }
                   }); 
                             }

  body.on("click", ".all-forms-link", function() {
        loadForms(); //or something similar
   }); 

Answer №1

Absolutely. If you define a named function like this:

function foo(){
   . . .
}

You can use that function by its name wherever a function is required.

Therefore, your code could be simplified further as shown below:

function loadForms() {
  console.log("AJAX Call Initiated!");
  $.ajax({ 
    url: "forms.php", 
    type: "post", 
    data: {formsPage: 1}, 
    success: function(data) {
      stage.html(data)
    }
  }); 
}

// Simply refer to your function's name (without adding parenthesis 
// because we are not executing it here, just referencing it) where a function is expected.
$(document).on("click", ".all-forms-link", loadForms);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="all-forms-link">Click me</div>
