Could someone explain why the window.onload function is not functioning as expected on my other Vue page?

I am facing an issue with my two pages or "views" that have identical JS code. Both pages have a window.onload function where I perform some actions:

console.log("loading")

window.onload = function() {
console.log("loaded")
// do stuff
}

The problem is that window.onload is being skipped and not executed at all on one of the pages, never reaching the console.log("loaded") statement.

Interestingly, window.onload works perfectly fine on the main page (Index.vue) but fails to execute when navigating to the secondary page (About.vue). I suspect it might be related to how Vue.js loads components using the router. Can anyone help me identify the issue?

Answer №1

Indeed, once you navigate, the code will not run again because the DOM has already been loaded. Feel free to execute your functions without relying on window.load.

To guarantee that the component is fully mounted on the DOM, consider utilizing the mounted lifecycle hook in Vue.
