In my @products table displayed on index.html.erb, clicking on any product triggers an AJAX request to load the _show.html.erb partial. However, I'm wondering if there's a way to automatically have the first product load on the page without requiring a click for the AJAX request.
Currently, when the initial page loads, the area where the partial should render remains blank until a product is clicked. I want the first product to be loaded upon opening index.html.erb.
In response to your inquiry, I have 2 different strategies that can be implemented.
Strategy 1:
Utilize the document.ready function to make an AJAX call for displaying the first product. This way, the call will be triggered without requiring an explicit click, creating a lazy loading effect.
Strategy 2:
Simply update your index code and use partial rendering to display the first product in the designated area where you anticipate _show.html.erb to appear. The approach could look something like this:
<%= render :partial => "show", :locals => { :product => @products.first }%>
# PRODUCT TABLE
<%- @products.each do |product| %>
<% PRODUCT ROWS %>
<% end %>
Please note: the syntax for rendering partials may differ depending on the context.
After some trial and error, I finally found a solution to my problem. By observing that the AJAX request functioned correctly when manually clicking on the product link, which triggered the display of the 'show' partial, I was able to replicate this behavior by including a script tag on the 'index' page. This script tag allowed me to programmatically issue a click event on the first product, ensuring that the 'index' page did not load with an empty product list.
<script type="text/javascript">
setTimeout(function() { $("#js-products a")[0].click(); }, 3000 );
</script>
