Tips for ensuring that an Ajax request successfully executes when a page loads

I have a question about implementing an AJAX request in my code. Currently, I have the text on the screen updating when a dropdown input is selected using 'onchange'. However, I also want this same behavior to occur on page load, but I am struggling to find the correct syntax.

$(document).on('change','#standalone-invoice-billpayer', function (evt) {
       updateCardDetailsText(evt)
    });

Currently, clicking on the dropdown triggers the function with the AJAX request, which works perfectly. But now I want this same functionality to happen automatically on page load. I am working with Ruby on Rails and would appreciate any assistance or guidance. Thank you!

Answer №1

To ensure functionality with Turbolinks, it is necessary to include an event listener for the turbolinks:load event. Adding a listener for the jQuery.ready event will only trigger once on the initial page load and not when the page is replaced by Turbolinks.

Turbolinks initiates a sequence of events during navigation. Among these, the turbolinks:load event holds particular importance as it triggers upon the initial page load and after each visit using Turbolinks.
- https://github.com/turbolinks/turbolinks#observing-navigation-events

document.addEventListener("turbolinks:load", function(evt) {
  updateCardDetailsText(evt);
});

If you are not utilizing Turbolinks, you can simply use jQuery.ready:

// shortcut for jQuery.ready(function(){ ... });
$(function(){
  updateCardDetailsText(evt);
});

You also have the option to trigger the ajax call immediately upon script loading and then manipulate the DOM once it is ready:

jQuery.getJSON('/foo.json').done(function(data){
  $(function(){
    modify_the_dom_with(data);
  });
});

This approach can greatly optimize performance, especially for elements loaded via ajax, resulting in a more responsive user experience.

Answer №2

Activate the change event on the specified element within the code:

$(function() {
    $(document).on('change','#standalone-invoice-billpayer', function (evt) {
       updateCardDetailsText(evt)
    });
    $("#standalone-invoice-billpayer").change();
});

By using .change(), the event handler will be triggered, subsequently executing updateCardDetailsText().

Answer №3

Understanding the correct way to trigger an event is crucial, but keep in mind that the evt value will simply adopt the default value set in the element "#standalone-invoice-billpayer"

$(document).on("turbolinks:load",function() {

 $("#standalone-invoice-billpayer").trigger('change');

});
