How to set a parameter in a URL?

Question

JavaScript

Good afternoon
I have a page with a conditional button. And I want to formulate a URL so that when you click on it, the page is loaded and the button is pressed (or the function that clicks on it is executed). How can this be done?

Answer 1

google window.location.hash
with it, you can read the parameter btn from the url of the view,
then it remains only at the time of page load to check whether there is such a parameter or not and do the necessary actions, something like this

window.addEventListener('load', function() {
    if (location.hash=='#btn') {
         console.log('Press btn');
    }
})

and you can dynamically generate a link like this
let url = document.location.href + '#btn';
