Javascript Course


The location object is part of the window object (but also of the document object), and provides access to the current URL and its components. It can be accessed through the window.location property (or document.location).

window.location (or document.location ) returns the full URL address. But if you assign it a value (a string with a URL address) will load the page from that URL (makes redirect to that address).

- Example, it displays the full address of the page, and after five seconds it redirects to another address (in iframe if the script is into an <iframe>).
document.write('<p>Current address:<br>'+window.location+'<br><br>- After 5 seconds redirects to: //gamv.eu</p>');
window.setTimeout(()=>{window.location ='//gamv.eu';}, 5000);
This object has properties and methods that can be called with the syntax:
window.location.property_name
window.location.methodName()
