Redirect using url parameters

Question

This one is a redirect code, I used it without url parameters, but now I need it to work according to the parameters and I could not, I am very new in javascript, could someone explain to me what I am doing wrong in my code?
If ver is equal to 1, do nothing, otherwise run window.location.replace("https://www.google.com");

var url = new URL(window.location);
var ver = url.searchParams.get("ver");

document.onload = function() {

   if(ver == 1) {
      return false;
   }

   else {
      window.location.replace("https://www.google.com");
   }
}

Answer 1

The event onload shall not apply to document, but to the object window.

Change to:

window.onload = function() {...

Now, wouldn’t it be more interesting to check whether ver is different from 1, since the else will consider any value other than 1?

if(ver != 1) {
  window.location.replace("https://www.google.com");
}
