Hotlst.biz improves script loading: moving away from $.getScript
The Hotlst.biz team has optimized JavaScript performance on the platform by replacing $.getScript with dynamic creation of <script> elements using plain JavaScript.
Previously, scripts were loaded like this:
Code: JavaScript
$(function(){
if ($(".hotengine-shop-products-add-count-spinner").length){
if(typeof $hotengine_shop_product_count_spinner == "undefined"){
$.getScript("/templates/scripts/hotengine-script-shop-product-count-spinner.js?v33").fail(function(jqxhr, settings, exception) { console.error("Failed to load script: ", exception);
});
}
}
});Now, a different approach is used:
Code: JavaScript
$(function(){
if ($(".hotengine-shop-products-add-count-spinner").length){
if (typeof $hotengine_shop_product_count_spinner == "undefined"){
const s = document.createElement("script");
s.async = true;
s.src = "/templates/scripts/hotengine-script-shop-product-count-spinner.js?v34";
s.onerror = (e) => { console.error(`Failed to load script: ${s.src}`, e); };
document.head.appendChild(s);
}
}
});Why this is recommended:
- No jQuery required, fewer dependencies.
- Control over duplicate loading: script is inserted only once.
- Asynchronous loading improves performance without blocking the page.
- Simple and predictable error handling via
onerror. - Code is more modern and compatible with plain JavaScript.
