JavaScript - Location

The window.location object contains many properties and methods and can be used to get the current page address (URL) and to redirect the browser to a new page.

The window.location object can be written without the window prefix. Some examples:

• window.location.href returns the href (URL) of the current page
• window.location.hostname returns the domain name of the web host (ip or url)
• window.location.pathname returns the path and filename of the current page
• window.location.protocol returns the web protocol used (http:// or https://)
• window.location.assign(url) loads a new document (takes url)

let output = "";
let Location =
{
    Href: window.location.href,
    HostName: window.location.hostname,
    PathName: window.location.pathname,
    Protocol: window.location.protocol,
    Assign: window.location.assign
}

output += "href: " + Location.Href + "<br />";
output += "hostname: " + Location.HostName + "<br />";
output += "pathname: " + Location.PathName + "<br />";
output += "protocol: " + Location.Protocol + "<br />";
output += "assign: " + Location.Assign + "<br />";

document.getElementById("demo1").innerHTML = output;

Here is a simple example on how to use assign to send the user to another URL.

function GetOuttaHere()
{
    window.location.assign("http://www.google.com");
}
