Introduction
This tip teaches you how to allow your readers to jump back to their previous pages from the current page.

Is there a magic button that can be placed anywhere in your HTML document, so that your readers can jump back from the current page to the previously viewed page? Maybe you are not as lazy as I am, but it's not strange to think about it. When the page is very long, I hate to move the mouse over the "back" button of the browser.

<A href = "javascript: history. Go (-1 )"
Onmouseover = "self. Status = Document. referrer; return true"> go back </a>

You must pay attention to the following points:

• This technique is only valid in browsers that support JavaScript (such as Netscape Navigator.
• When you move the cursor over "back", the target URL is displayed in the status bar,However:
  • For some strange reason, this function is only valid when the page is linked from a hot link.
  • If you directly enter the URL or use JavaShowdocument ()To display the page.NoThe target URL is displayed in the status bar.
