How can I get greasemonkey to call a function on a page after it loads

Question

I have a very simple greasemonkey script that I want to call an already existing javascript function on the page. I\'ve read the documentation and nothing seems to work

Answer 1

You could try using javascript event listeners.

These execute code on response to object events occurring (such as page load)

For example, to execute code on page load:

window.addEventListener('load', function () 
{
    /* code goes here */
}
