String Replace in a URL

Question

I need to replace the URL in the DIV with ID "___gcse_1". I created a new function, replace_url (), but adding the domain in full does not work, as there are syntax problems. my code below:

async function sostituisco_url() {

  var str = document.getElementById("___gcse_1").innerHTML;
  var res = str.replace(/www.sitoweb.it//gi, "nuova_url");

  document.getElementById("___gcse_1").innerHTML = res;
}

window.onload = sostituisco_url;

That seems like a bad way of doing it... You're destroying the entire DOM and rebuilding it, all to change... what, a link's URL? You'd be better off selecting the link and changing its .href — Niet the Dark Absol

You might need to escape the last / in your regex, such as /www.sitoweb.it\//gi. But above advice is a far better idea — Cid

Why? AFAIK forward slashes have no special meaning in regular expressions, except in Perl, where they may delimit the regex. But this isn't a Perl question.

in javascript they have no meaning in The Regular Expression but it is a key charecter and its indicates start point and end point of a regular expr in a string. you noticed that in the example above after indication the end of regular expression with "/" i use "g" for global and "i" for in-case-sensitive those are not as part of The regular Expression.

Cool, thanks for clarifying. Maybe edit this into your answer?

Please try this. str.replace(/www.sitoweb.it//gi, "nuova_url");
