show more/Less text with just HTML and JavaScript

I am needing to create a show more/less text function, but with just JavaScript and HTML.. I can't use any additional libraries such as jQuery and it can't be done with CSS. The sample code I have added displays the 'more' text, but not the 'less'.

If someone could point me in the right direction, it would be much appreciated.

I've spent the majority of the day frying my brain over this, as its clearly not the modern way to do it, however, my HTML is:

<html>
<head>
<script type="text/javascript" src="moreless.js"></script>
</head>

<body>
Lorem ipsum dolor sit amet
<p>

<p id="textarea"><!-- This is where I want to additional text--></div>
</p>

<a onclick="showtext('text')" href="javascript:void(0);">See More</a>
<p>
Here is some more text 
</body>
</html>

and my JavaScript is (moreless.js):

function showtext()
{
var text="Here is some text that I want added to the HTML file";
document.getElementById("textarea").innerHTML=text;
}

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.

The missing piece you've been looking for is to create an if statement. This allows for you to toggle your text.

More on if statements here.

JSFiddle: http://jsfiddle.net/8u2jF/

Javascript:

var status = "less";

function toggleText()
{
    var text="Here is some text that I want added to the HTML file";

    if (status == "less") {
        document.getElementById("textArea").innerHTML=text;
        document.getElementById("toggleButton").innerText = "See Less";
        status = "more";
    } else if (status == "more") {
        document.getElementById("textArea").innerHTML = "";
        document.getElementById("toggleButton").innerText = "See More";
        status = "less"
    }
}
