JavaScript Automagically Hide And Show An HTML Tag (DIV, P, Whatever)

  • submit to reddit
        If you want to hide or show an HTML tag using JavaScript, you can use the function below. It also changes the name of the link.

Here's the HTML code:
<a href="javascript:viewMore('two');" id="xtwo">... more</a>
<p>I see one.</p>
<p id="two" style="display:none">I see two.</p>

Here's the JavaScript code:
function viewMore(div) {
	obj = document.getElementById(div);
	col = document.getElementById("x" + div);
	if ( == "none") { = "block";
		col.innerHTML = "... less";
	} else { = "none";
		col.innerHTML = "... more";
