Question

I want to replace “http://” “https://” “www.” and also explode the url on “/”.

For example: http://www.google.com/whatever should return google.com

I was doing as much as I knew how on this function:

// Change site's title
function changeTitle(url) { 
    var title = url.replace("http://", ""); // 1
    title = title.replace("https://", ""); // 2
    title = title.replace("www.", ""); // 3
    document.title = title; 
}

But I want to do all the process on a separate function, e.g: function cleanUrl(url). I tried this and variants but couldn’t make it work:

// Clean URL
function cleanUrl(url) { 
    var title = url.replace("http://", ""); 
    title = title.replace("https://", ""); 
    title = title.replace("www.", ""); 
}

// Change site's title
function changeTitle(url) { 
    cleanUrl(url);
    document.title = title; 
}

How do I do it? Also I’m not exploding the url since I didn’t know how.

Answer 1

// Clean URL
function cleanUrl(url) {
    var title = url.replace("http://", "");
    title = title.replace("https://", "");
    title = title.replace("www.", "");
    var exploded = title.split('/');
    title = exploded[0];
    return title;
}

// Change site's title
function changeTitle(url) {
    title = cleanUrl(url);
    document.title = title;
}
