How to create an HTML back button
Insert the following HTML into your web page:
<form> <input type="button" value="Go back!" onclick="history.back()"> </form>
The result looks like the button below. If you click it, you go back to the previous page in your history.
The history.go() method tells the browser to go to a specific page in the user's browsing history. You can specify which history item by putting a number inside the parentheses. With computer programming, this is called an argument.
If you specify the number -1 as your argument, the browser goes back one page in the browser's history. Here's the same code as above, using history.go(-1) instead of history.back().
<form> <input type="button" value="No, really, go back!" onclick="history.go(-1)"> </form>
