document.getElementById to include href - href

Question

<script type="text/javascript">
document.getElementById("IDOFELEMENT");
</script>
What is the correct way to turn this into a link?
Can I write
<script type="text/javascript">
document.getElementById("IDOFELEMENT").href("http://www.address.com");
</script>
Many thanks.

Answer 1

javascript:
// this changes the href value<br>
document.getElementById("IDOFELEMENT").href = "http://www.address.com";
and the html:
<a href="www.toBeChanged.com" id="IDOFELEMENT">To Website< /a>

Answer 2

You should specify what kind of element is IDOFELEMENT. But you can't convert it to a link by just adding a href attribute, it only works if IDOFELEMENT
is an hyperlink like <a id="IDOFELEMENT">stuff</a>
Simplest way is to add an onclick event to the element that changes the url to desired address:
<script type="text/javascript">
var element = document.getElementById("IDOFELEMENT");
element.setAttribute('onclick', 'window.location.href=\'http://address.com\'');
</script>
Or if you wanna wrap it with a hyperlink:
<script type="text/javascript">
var element = document.getElementById("IDOFELEMENT");
var parent = element.parentNode;
var link = document.createElement('a');
link.href = 'http://www.address.com';
link.appendChild(element.cloneNode(true));
parent.replaceChild(link, element);
</script>
I hope this helps you.

I came accross the issue - Javascript error: Cannot read property 'parentNode' of null.
I discovered this was due to executing this code while the DOM is not ready.
window.onload solved the issue for me.
<script>
window.onload = function() {
var element = document.getElementById("IDOFELEMENT");
var parent = element.parentNode;
var link = document.createElement('a');
link.href = 'http://www.google.com';
link.appendChild(element.cloneNode(true));
parent.replaceChild(link, element);
};
</script>

You just need to wrap your element in an anchor tag as follows...
<a href="http://www.address.com">
<div id="IDOFELEMENT">
... content ...
</div>
</a>
