Onclick javascript to make browser go back to previous page?

Add this in your input element

<input
    action="action"
    onclick="window.history.go(-1); return false;"
    type="submit"
    value="Cancel"
/>

history.back()

or

history.go(-1)

Put this to the button onclick handle. It should look like this:

<input name="action" onclick="history.back()" type="submit" value="Cancel"/>
