How to get the previous page URL using JavaScript? [duplicate]

How do I get the URL of previous page in JavaScript?

Say, I go from page A to B, and use browser back button to go back to page A.

I've tried to use history.previous, but I'm can't get it to work.

Solution 1:

You can use the following to get the previous URL.

var oldURL = document.referrer;
alert(oldURL);

Solution 2:

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

Solution 3:

You want in page A to know the URL of page B?

Or to know in page B the URL of page A?

In Page B: document.referrer if set. As already shown here: How to get the previous URL in JavaScript?

In page A you would need to read a cookie or local/sessionStorage you set in page B, assuming the same domains
