上一个和下一个按钮

Question

My website has previous and next buttons. When the page loads id like the previous button to be invisible.(on the first panel) After the user clicks the next button (to go to 2nd panel), id like the previous button to appear.

Is there some javascript that will do this?

Answer 1

Add a CSS display: none; to the Previous button then add an onclick event to the button:

<input id="next" type="button" name="next" onclick="document.getElementById('previous').style.display = 'block';
" />

Where #previous = the ID of your previous button.
