Okay someone made the buttons for my spoiler code but actually now that I have this, I don't know what to do next. As in make it hide and show stuffs just like a spoiler code but with these buttons.

CODE
<input value="Show" style="margin: 0px; padding: 0px; width: 45px; font-size: 10px;" onclick="if (this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display != '') { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = '';this.innerText = ''; this.value = 'Hide'; } else { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = 'none'; this.innerText = ''; this.value = 'Show'; }" type="button">


Anyone with java knowledge please help.
