previous_pages.js

This JavaScript library builds an array of the page title and URL of every page that's visited with the library included. This can be useful for things like dynamic back buttons, analytics, 404 pages etc.

Functions

• get_previous_page(int index) - Returns the previous page, or the previous page with the given index.
• get_previous_pages() - Returns all previous pages.
• clear_previous_pages() - Removes the previous_pages cookie.

Example Usage

var previous_page = get_previous_page();
console.log('Title: '+previous_page.title+' URL: '+previous_page.url);

Notes

Out of the box, this library gets the page title, and takes the part before |. If this doesn't suit your needs, change the following:

var new_page = {
  url: window.location.href,
  title: document.title.split(' | ')[0], // <-------
};

The array we store as a cookie is limited to 20 items to stop the cookie from becoming huge.
