Dynamically loading external JavaScript for an Angular component and triggering the window load event

I am currently dealing with an external javascript file that I only want to be included on a specific component, so the approach I'm taking involves dynamically loading it. I came across this answer that explains exactly how to achieve this.

The problem arises because the javascript file I'm working with executes some tasks when the window is fully loaded:

$(window).on('load', function() {
    //Some logic
});

Considering that I am loading this script dynamically for a particular component, the logic inside it never runs as the load event has already fired before the script gets loaded. Is there a way for me to trigger this logic after successfully loading the script?

Answer №1

If you encounter issues with firing the window.load event, try triggering it after loading the script. Keep in mind that some scripts might be affected if they are bound to this event and expect it to happen multiple times.

const evt = document.createEvent('Event');  
evt.initEvent('load', true, true);  
window.dispatchEvent(evt);

Another approach could be to carefully recreate the code executed after the window loads, since you seem familiar with how the script functions. This may help minimize any negative impacts caused by re-triggering the load event.

Both solutions may be considered temporary fixes. It might be advisable to explore using a different component that is not reliant on other frameworks or specifically designed for use with Angular.
