Callback functions and ready-made scripts

☰

Example of callback functions after JavaScript execution

The site uses many functions, after which you may need to execute your own scripts. For this purpose, we have added a set of callback functions that are called after script execution, with a preliminary check of their existence.
For example, after adding a product to the cart, the function callback_hotengine_cart_plus_after is called, if it exists

Code: JavaScript

if(typeof(callback_hotengine_cart_plus_after) === "function"){ 
callback_hotengine_cart_plus_after(); 
}

To run your own script of the function callback_hotengine_cart_plus_after, you need to create it.

Code: JavaScript

window.callback_hotengine_cart_plus_after = function(){
  // your script
};
