Switching link text and href without page refresh..

cgm225

I have a "pause" link that I want to read "play" after the javascript behavior has been paused. However, I want to do so without a page refresh. Restated, I want a play/pause toggle. Here is a example slideshow page of where I would like to use that type of functionality.

Any ideas?

Thank you all in advance!

Here is a sample that you can work into your current code to do this.

function showControl()
{
	var control = document.getElementById("control")
	var currentText = control.innerHTML;

if (currentText == "Play")
{
	control.innerHTML = "Pause";
}
else
{
	control.innerHTML = "Play";
}
}

</script>
<a href="#" id="control" onclick="showControl();">Play</a>

What function (similar to innerHTML) can be used to specify the href of an element?

Killzone_Kid

.getAttribute('href');
.setAttribute('href','your new link');

the link text you can access via .firstChild.nodeValue

@Killzone_Kid - thank you so much for your reply.

However, could you explain the .firstChild.nodeValue comment a little more because I don't completely follow what that is/does.

Thanks again!

What's between <a> and </a> is your text of the link which is also child to the <a> element. So .firstChild specifies you need to look for the first node right after <a> which is the text node with the text of the link and .nodeValue should get you the value. Well something like that.
